Princess Cut Diamonds

The Princess Cut Diamond is a brilliant style diamond shape with sharp, uncut corners. It is typically cut square although there are sometimes princess cut diamonds that have a rectangular shape.

The princess cut is the most important new cut or shape for diamonds since the invention or perfection of the modern brilliant cut over 60 years ago. The princess cut diamond is effectively a square version of the round brilliant cut, and is known technically as a square modified brilliant cut.

The princess cut was originally created by Israel Itzkowitz in 1979 at Ambar Diamonds in Los Angeles. After three years of optical research the princess cut was developed. It was a square diamond from the girdle up that had faceting similar to that of a round brilliant cut diamond from the girdle down. This accounts for the fire and brilliance seen in princess cut diamonds.

Princess cut diamonds are the most popular non-round diamond. They have a beautiful brilliance and a modern square shape that accentuates a diamond’s fire rather than its luster. Princess cut diamonds have become a favourite diamond choice for engagement rings.

The princess cut diamond is usually less expensive than a round brilliant cut diamond of the same carat weight because a diamond cutter usually does not need to shave off as much diamond weight from the rough diamond. This ability to retain more crystal weight makes this shape popular amongst diamond cutters and therefore less expensive than round brilliant cut diamonds.

The princess cut diamond is normally close to a square with a + or – 10% deviation, but it may come in more elongated versions. Try to avoid extremely thin girdles which are prone to chipping when being set. For a princess cut diamond that is square, a length to width ratio between 1:0 – 1:10 is best, if you prefer a more rectangular shape then a length to width ratio above 1:11 is best.

Diamond Imports has an exceptional range of Princess Cut Diamonds. A Princess Cut Diamond generally has 76 facets, giving it more brilliance and fire than the round brilliant. Princess cut diamonds are the most popular non-round diamond. They have a beautiful brilliance and a modern square shape that accentuates a diamond’s fire rather than its luster. Princess cut diamonds have become a favourite diamond choice for engagement rings.

Diamonds: Diamond Buying Advice

When you start to think about buying a diamond, you naturally will want the best diamond that you can afford and a beautiful stone you will treasure forever. Diamonds can be found in a range of shapes, sizes, qualities & colours. If you are about to buy a diamond for an engagement ring, you may want to consider spending the commonly accepted guideline of two months’ salary. However you should spend as much as you can comfortably afford. Buying a diamond is not like buying a car which will depreciate over time, they endure generations and are passed down in your family as an heirloom. Remember, diamonds ARE forever.

When buying diamonds, make sure you buy the best quality diamond that is within your budget. Do not buy a diamond just because it has been “discounted”or the diamond dealer is offering a “special price”. These “sale” prices and deals are nothing more than marketing hype and will not result in any real savings to the price of a diamond. The price of diamonds is controlled by international market conditions and the availability. Unlike other jewellery items, diamonds do not go on sale because they do not have huge profit margins or over inflated prices.

Do not confuse a diamonds carat weight with the size of a diamond. Two diamonds that have the same carat weight could have very different diameter measurements and appearance in actual size. A poorly cut 1.00ct diamond may look like a 0.75ct diamond from the top because they have the same diameter measurements even though their carat weights are different.

Diamonds are sold by their carat weight. A diamond cutter always tries to retain as much carat weight and as few inclusions when cutting a diamond. Sometimes the cut of a diamond might be sacrificed in order to produce a diamond with a higher carat weight. Diamonds that have a higher cut quality – excellent, ideal and very good cut diamonds – will sparkle with far more brilliance and fire than poorly cut diamonds which have a lower cut grade.

The value of a diamond is determined by its exact quality as defined by the 4C’s: Cut, Colour, Clarity and Carat-Weight. It is the sparkle or brilliance that gives a diamond its unique quality. Many people become overwhelmed when they start searching for a diamond. It seems that the fear of either buying a diamond that is not very good quality or paying too much can cause people to go on a quest to become a diamond expert overnight. Getting knowledge and educated about diamonds and the 4C’s – Cut, Colour, Clarity & Carat Weight – is a big first step towards buying the right diamond.

Before you start diamond shopping, it is best to have an understanding of what you are buying and the process behind buying a diamond. Today on the internet there is no shortage of information available, especially when it comes to learning about diamonds. Here are a few important steps when embarking on the purchase of a diamond –

Gain a basic understanding of the qualities of a fine diamond.

Learn about diamonds, do your homework before you start looking. There are many good websites that offer comprehensive Diamond Education sections where you are able to learn about diamonds and The 4C’s – cut, colour, clarity and carat weight. These are the criteria that diamonds are graded and valued upon.

Set a personal budget.

This will dictate a lot of the parameters for the diamond you are searching for. Then obtain a realistic idea of what diamonds cost and the various diamond prices. Round Brilliant Cut Diamonds are the most popular shape of diamond for engagement rings however they also are higher priced than a fancy shape diamond. Setting a personal budget will save you a lot of time and it will help you to not over extend yourself financially.

Decide on the diamond specifications.

What shape of Diamond do you prefer? Remember that diamonds are cut in many different shapes besides Round Brilliant and Princess Cuts. Fancy Shape diamonds such as Asscher, Cushion, Emerald, Oval, Pear, Marquise, Trilliant and Radiant Cut Diamonds all make unique engagement rings and create beautiful jewellery when set in individual designs. Once you have decided on the shape of the diamond you wish to buy then start deciding on your other preferences such as the carat size, the diamond colour, the diamond purity and the diamond cut quality.

Insist on a Diamond Certificate.

A diamond certificate or diamond grading report documents the complete quality and description of the diamond, it includes information on shape, carat weight, clarity, fluorescence, colour grade, measurements, proportions and finish grade. A diamond certificate also confirms that the diamond is natural and is not synthetic or man-made. Diamond Grading Laboratories such as GIA, AGS, HRD & DCLA are all internationally recognized and compliant grading laboratories.

View the diamond in person where possible.

Compare the quality of the diamond next to other diamonds before you purchase. Cut is the only factor that man can control. Cut refers not only to the shape and style of the diamond, but its proportions, symmetry, and finish or “make”. Cut determines the brilliance and fire of the diamond and is actually one of the most important aspects to consider when choosing your diamond.

We understand that when searching for the right diamond the task can at times be daunting and very confusing. Just comparing diamonds on price alone is not nearly good enough, you need to be able to compare the diamonds next to each other to see which diamond is the better quality and appeals to you the most.

Price of Diamonds

What Influences The Price of Diamonds?

Diamonds are cut in a range of shapes, sizes and qualities all of which influence the price. Diamonds that have an excellent or very good cut grade will reflect maximum fire, brilliance and sparkle and the price of these diamonds will be higher than diamonds with a good cut grade.

The Shape of Diamonds

Round Brilliant Cut Diamonds are the most popular diamonds for diamond engagement rings followed by Princess Cut Diamonds. Any diamond that is not Round in shape is known as a Fancy Shape Diamond. Asscher, Cushion, Emerald, Heart, Marquise, Oval, Pear, Princess, Radiant and Trilliant cut diamonds are all fancy shape diamonds.

Round Brilliant Cut Diamonds are the most expensive mainly because when cutting a Round Brilliant Cut diamond there is a greater loss in rough which has to be factored into the price. Another reason why Round Brilliant Cut diamonds are priced higher is because they take longer to polish and cut than other diamond shapes and the demand for Round Brilliant Cut diamonds is greater than all the other diamond shapes.

Clarity Influences Diamond Prices The Most

The clarity grade of a diamond influences the price obtained more than any of the other factors. Diamonds that have high clarity grades of VVS1 or VVS2 have extremely hard to find inclusions even with a jewellers 10x loupe. These diamonds are almost pure and rarer to find than diamonds with lower clarity grades such as SI1 or SI2 and therefore command a much higher price. The rarest of diamonds have an Internally Flawless Diamonds -IF or Loupe Clean clarity grade and these diamonds fetch premium prices.

Colour Influences Diamond Prices

Colour is another important factor that influences the price of a diamond. Diamonds are graded for their colour alphabetically starting at D colour going down to Z colour. Diamonds that are colourless or show the least amount of colour obtain the highest prices along with fancy coloured diamonds such as pink, red, green and blue diamonds. Diamonds that display the least amount of colour are known as exceptional white. Exceptional white diamonds includes D and E colour graded diamonds. Rare white is the next colour grade and this includes F and G colour diamonds. H colour diamonds are graded as white and I and J colour diamonds are known as slightly tinted white diamonds.

Cut Influences Sparkle, Shine & The Price of Diamonds

Did you know that if the diamond is poorly cut, the colour and clarity can not make up for it? The cut of a diamond is what makes a rough diamond sparkle and shine. If a diamond is poorly cut, the light that enters the diamond from above will leak out of the sides and bottom of the stone, and the diamond will not have the optimum amount of sparkle or fire—regardless of its colour or clarity.

Excellent and Ideal Cut Diamonds have been cut to precise standards to display the beauty of the diamond. Excellent and Ideal Cut Diamonds have perfection in proportion, symmetry and polish and they will always display the maximum brilliance, fire & scintillation.

Excellent and Ideal Cut Diamonds have properly proportioned facets, excellent symmetry & polish. Since 97.5% of a diamond’s brilliance is controlled by the quality of the cut Excellent and Ideal cut diamonds obtain higher prices. The Diamond Cut Grade is made up of three main controlling factors – Proportion, Symmetry and Polish. The light return of the diamond more commonly known as sparkle or brilliance is also an important factor but it is governed by the proportions and symmetry of the diamond cut.

Diamonds with a Very Good cut grade reflect most of the light that enters them, dispersing a good deal of brilliance. Very Good cut diamonds have proportions which often overlap and are comparable to Excellent cut diamonds but just differ slightly in one area or measurement. Very Good cut diamonds are also highly valued.

Diamonds are Sold By Carat Weight

Carat is a unit of measure not size. Two diamonds that have the same carat weight may appear to be different sizes depending on how the diamond is cut. Some diamonds will have extra weight on the bottom part of the diamond, the pavilion, or a thick girdle and therefore will appear smaller visually.

Diamonds are sold by their carat weight. The heavier a diamond weighs once it is cut the higher the price per carat. A diamond cutter always try to retain as much carat weight and as few inclusions when cutting a diamond in order to obtain the best possible price per carat. Sometimes the cut of a diamond might be sacrificed in order to produce a diamond with a higher carat weight. Hundreds of tons of rock and ore must be processed to uncover a single one-carat gem quality diamond.

4C’s – Cut, Colour, Clarity & Carat

After diamonds have been sorted into their different shapes they are then assessed with what is known as The 4C’s- The Cut, Colour, Clarity and Carat weight. These individual factors are all combined resulting in the price of the diamond. The price of diamonds is also influenced by international market conditions such as exchange rates, supply and demand, fashion trends as well as inflation.

Diamonds, just like your marriage, are an investment, and have been an investment device for several thousand years. Diamonds are a symbol of love and commitment so buying the perfect diamond for an engagement ring or that special occasion is a crucially important decision.

What Diamonds Cost

What Do Diamonds Cost?

Guys who are ready to ask for a woman’s hand in marriage will inevitably attempt to figure out how much money they should spend on a diamond engagement ring, what the diamond will cost them and whether they will be able to afford a diamond engagement ring for their fiance. Most people have heard the expression that diamond engagement rings cost two months’ salary.

Where did the two months of salary idea come from?

The origin of the two months’ salary began with DeBeers, the largest diamond producer and diamond marketer in the world. In 1947, DeBeers decided to promote diamonds following the depressed wartime market. DeBeers launched a marketing campaign with a New York advertising firm. A copywriter penned the famous slogan “A diamond is forever” that is now synonymous with Diamonds.

De Beers wanted to bring diamonds to the masses, make them seem more affordable, rather than have them just for sold to the wealthy and select few. Accordingly, the price of a diamond for an engagement ring was set at approximately two months of salary.

This was a concept that everyone could understand, it was aimed at the groom-to-be and therefore made buying a diamond for an engagement ring achievable no matter whatever his salary was. No longer did people think of diamonds as being something which they could never afford, they now had a figure to relate to in simple terms – two months salary.

The two months salary became the norm and in the mind of the groom it was the predetermined acceptable price for a diamond engagement ring. As a general guide usually grooms spend bewteen 10 – 20% of their annual salary on a diamond engagement ring.

At Diamond Imports – www.diamondimports.com.au – we have an exceptional range of certified loose diamonds that create stunning diamond engagement rings.

GCAL Earns ISO Laboratory Accreditation

RAPAPORT… New York (April 24, 2008)– After a rigid auditing period, Gem Certification and Assurance Lab (GCAL) was awarded ISO 17025:2005 accreditation, meaning that it conforms to recognized international standards for accurate and reliable grading. Specifically, this recognition means that GCAL’s lab is rated among the most technically competent in the world.

Laboratory Accreditation Bureau (LAB), the firm that performs certification assessment, provides third party attestation of technical confidence. “Laboratory tests are supposed to be repeatable and verifiable—we should all be doing it the same way,” explains Jason Stine, Testing Program Manager for LAB. Currently, GCAL is the only diamond grading lab in North America to earn this prestigious certification, and it is one of only three diamond grading labs in the world that is ISO 17025:2005 accredited.

This coveted certification stands for reassurance and minimal risk. An accredited lab offers several distinctions for its customers including accurate grading the first time/less retesting, enhancing consumer confidence, and making goods more easily accepted overseas. Because ISO is internationally recognized, exporters don’t have to retest for most other markets: Over 40 laboratory accreditation bodies have signed a multilateral recognition statement called the ILAC Arrangement, which greatly enhances the acceptance of data across the borders of member countries.

GCAL will continue to be tested periodically to ensure compliance with all regulations and standards. According to Donald A. Palmieri, president of GCAL, ISO accreditation is a tremendous milestone in the company’s growth and expansion. “We are very proud to be the first lab in this country to conform to ISO laboratory standards, and we see it as a testament to offering the most reliable and accurate grading in the industry. Our customers expect more from GCAL, and we want to live up to that expectation regardless of the time, effort or cost it takes to be the best.”

Dazzling Cushion Cut Diamond 39.34 carats D Colour, Internally Flawless, Type IIa

What: An Unmounted, Cushion-Cut Diamond

Weight: 39.34 carats D color, Internally Flawless, Type IIa
Where: Christie’s, New York Jewels–The New York Sale April 16, 2008
How Much: Pre-Sale Estimate:USD$6 million to USD$8 million
Final Selling Price: USD$6,873,000
***

An extremely rare diamond of 39.34 carats was the clear-cut winner at the Christie’s jewelry auction this week. The cushion-cut gem sold for $6,873,000 ($175,000 per carat) to a private collector from the Middle East.
A stunner in every way, the gem meets the criteria for a near-perfect stone. The sophistication of the stone is reserved for the finest diamonds, reminiscent of important stones found in the fabled mines of India’s Golconda region and several other mines in Brazil and South Africa.
The gem has perfect symmetry with a cut so precise it can stand completely balanced on its pointed end or cutlet. In addition, the diamond has no traces of colorant nitrogen, the characteristic that gives the stone such transparency and sparkle. Only 2% of all diamonds lack this chemical.
“The old-world charm of this beautiful gem, along with a softness to its cut and its superb brilliance, ranks it among some of the most sensational diamonds to have appeared for sale at Christie’s, such as the historical Polar Star, to [which] it bears a striking resemblance,” said Rahul Kadakia, head of Jewelry Americas at Christie’s.
The Polar Star diamond is one of the most famous diamonds in the world, having been owned by Russian royalty until its sale to the House of Cartier in the 1920s, and later selling at Christie’s Geneva in 1980 for $5.1 million, a huge sum at the time.
Artfact Analysis:
Christie’s sold $50 million worth of fine jewelry on April 16, making it the most valuable jewelry auction ever held in the U.S. Ten jewels sold for over $1 million each, and diamonds stole the show across the board.
The sale of this diamond bolstered overall confidence in the global trade for high-end gems. Last week, there was a moment of concern when Sotheby’s failed to sell a 75.22-carat, “D” flawless white diamond in Asia, though the gem was sold to a private buyer after the auction for an undisclosed sum. The pre-auction estimate was $10 million to $12 million, and the final price was likely not far off the asking price.
The next comparable diamond to hit the auction block is Christie’s 101-carat, near flawless, golf-ball-sized diamond, scheduled for sale in Hong Kong next month. The asking price will be around $6 million. There is every indication that the sale will be a success.
Last year, Sotheby’s sold a stunning 84-carat white diamond for $16.2 million to Guess! Jeans founder George Marciano, who named it the “Chloe Diamond” after his 12-year-old daughter.
The diamond was the second most expensive stone or piece of jewelry ever sold at auction, falling just short of the $16.5 million fetched by a 100-carat diamond at the same Sotheby’s
branch in Geneva in May 1995. Source : Nina West, Artfact.com/Forbes.com/Christies

Type of Diamonds

Natural diamonds are classified by the type and quantity of impurities found within them.

Type Ia – This is the most common type of natural diamond, containing up to 0.3% nitrogen.Clustered nitrogen atoms. Colourless to Yellow. 98% of all diamonds are Type Ia.

Type Ib – Very few natural diamonds are this type (~0.1%), but nearly all synthetic industrial diamonds are. Type Ib diamonds contain up to 500 ppm nitrogen. These diamonds about 0.1% prevalent.Isolated Nitrogen Atoms. Orange, Orange Yellow to Brown.Depending on the precise concentration and spread of the nitrogen atoms, these diamonds can appear deep yellow (“canary”), orange, brown or greenish.

Type IIa – This type is very rare in nature. Type IIa diamonds contain so little nitrogen that it isn’t readily detected using infrared or ultraviolet absorption methods. No specific colour centre.Yellow, Brown , Pink and Purple Type IIa diamonds have been documented. These diamonds are 1% to 2% prevalent.These diamonds can be considered as the “purest of the pure” – they contain no, or minuscule amounts of impurities, are usually colourless, highly transparent and can be a higher colour grade than D.Diamond Imports recently sold a round brilliant 1.36 carat D IF Ex/ Ex Type IIa.

Type IIb – This type is the rarest in nature. Type IIb diamonds contain no measurable amounts of nitrogen (even lower than type IIa) that the crystal is a p-type semiconductor.These diamonds contain no nitrogen – but they contain boron, which absorbs red, orange and yellow light. These diamonds therefore usually appear to be blue, although they can also be grey or nearly colorless. All naturally blue diamonds belong to Type IIb, which makes up 0.1% of all diamonds.
