DIAMOND CERTIFICATION

Perhaps the 5th ‘C’ when purchasing a diamond is the CERTIFICATE or diamond report. This important document validates the diamond’s characteristics. A diamond certificate from a ‘no name’ laboratory or jewellery shop is not worth the paper it’s written on, insist on quality grading documents. The world’s foremost diamond report and the leaders in diamond research are the inventors of the 4C’s; the GIA (Gemological Institute of America). There are other laboratories that also use the GIA methods and/or have a very good reputation, they are:

The diamond grading laboratories listed above are the largest, probably the strictest and certainly the most well known of the international gemological centres. There are subtle differences in grading techniques but the overall consensus is usually very close between these institutions. Any other diamond report may warrant further analysis of the laboratories processes and ability to grade in a consistent and unbiased manner that represents a true and fair diamond report. Because the diamond certificate reports the characteristics we have discussed above its vital and imperative it comes from a reputable source. A diamond valuation or appraisal is significantly different from a diamond report or certificate and should not be confused.

ALWAYS insist on a diamond certificate from a major laboratory!

Remember that when buying a diamond there are many characteristics that need to be balanced and reviewed in order to buy quality within your budget.

Every certificate from any lab. will carry its own disclaimer, this from an E.G.L certificate is typical:

‘This examination has been carried out using the current gemological procedures of E.G.L.
The report or seal expresses an opinion at the time of inspection of the stone, not a guarantee, valuation or appraisal. No representation or warranties as to accuracy are made. Diamond grading is not a science; It represents only the best professional opinion of this company [the EGL], which chooses its own standards or norms. A+/- 20% error of judgement is scientifically possible. E.G.L. is expressly held harmless by customers including, but without limitation for any claims or actions that may arise out of negligence in connection with preparation of this laboratory report or seal, or actions based upon the customer’s use of the certificate or seal’

DiamondGeezer.com stresses the following poignant points from this:-

  1. Diamond grading is not an exact science
  2. A certificate is not a guarantee, valuation or appraisal – It’s an assurance
  3. A certificate expresses a single opinion at the time of inspection of the stone
  4. One man’s VS is the next man’s Si
  5. Our advice, know where you are and insist on a certificate from the stricter labs and the GIA gets our strongest endorsement

Princess Cut. A Distinctive Choice

Though the Princess Cut is widely traced back to 1961 when London diamond cutter, Arpad Nagy, created a square cut that looked to compound the brilliance of the round brilliant cut, it was later in 1971, when the Barion Cut was renamed the Princess Cut, and later still in 1979 that the Quadrillion Cut was also merged into the Princess Cut approach.

The Princess cut is now second only to the round brilliant cut in popularity and is highly desirable and popular in pendants and engagement and eternity rings. The Princess cut weighs more than the round brilliant cut but there is a higher percentage of rough diamond. This reduces the price of the item but the diamond itself is distinctive and stands out.

The Princess Cut is an inverted pyramid shape, with 4 bevelled sides and enjoys the same high level of light dispersal as the round brilliant cut with facet levels of either 76 or 58. It’s square form also reduces the chances of shadowing and the bow tie effect and maximises the available light.

Another reason for its high popularity is that the Princess Cut creates an elongation to the finger, creating elegance and grace. Its distinctive style is perfect for non-traditional rings and items and, also for personalised designs and appears in many forms, other than wedding rings.

To talk to an expert about the most appropriate cut for you and possible design options speak to DiamondGeezer who will provide a series of Princess Cut inspirations. All designs are bespoke and rings are created by cutters with huge experience. The 30 day money back, or exchange, or tweaking service, is available on all items including personalised design so you can buy with full confidence.

All of DG Princess Cut diamonds are available in a range of styles, settings and pieces including pendants, necklaces and bracelets.

Asscher Cut Diamonds

The media has played a huge role in the increasing popularity of the Asscher Cut Diamond. Since the early episodes of US television hit Sex and the City, and celebrity engagements, such as Kate Hudson, the Asscher Cut diamond is now hugely back in fashion.

The Asscher Cut History

The Asscher Cut was produced in 1902 by the Asscher Brothers in Amsterdam and is a 58 faceted Cut. It was the first signature cut to be patented. The Royal Asscher Company was founded in 1954 and is still regarded as one of the world’s premier diamond cutters with a client list that includes royalty and A-list celebrities.
The Asscher cut is a stepped square cut, like the emerald cut, and has cropped corners. It is designed to focus the eye on the diamond, not the setting. Originally the designs matched the art deco style of pre First World War Europe but the appeal still lasts a century later and fulfils a retro demand for beautiful diamonds in a solid square format.

High Fashion

The current fashion appeal seems to centre on the focus of the diamond and there is a retro feel to the cut. Simply put the diamond is the star, ensuring the piece is not too feminine or fancy. Though the retro art deco them is often copied the Asscher cut is widely regarded as the setting that encapsulated the art deco period of grace and elegance.

The Perfect Jeweller

DiamondGeezer.com has a range of Asscher cut diamonds and offer 30 day money back guarantee. With our various accreditations with the British Jewellers Association, Assay Assured and Trust Pilot mean that you know you are dealing with a genuine company.

Emerald Cut. Traditional, Elegant.

There are 11 different, main cuts of diamond. Each one has a different set of benefits and appeal, and history. Some are new inventions, others hugely traditional. The Emerald Cut was in existence 500 years ago, when diamonds were cut in the “table” shape.

The art Deco movement, in the early 1920s in Europe and USA, is associated with the cut, but the name stems from the gem stone cutting, of the actual Emerald, that suited the shape and consistency of the diamond. When Rennie Macintosh represented square and rectangular shapes in his designs the only jewel to be fashionable in the art deco years was the Emerald Cut.

Also known as the square emerald cut, the emerald cut is a broad, flat pane with truncated comers. It has the ultimate step cut too, when viewed from high. There are 57 facets and the large number can increase the stone clarity, create a natural feel to the piece and helps create an elongation of the finger enabling elegance and grace.

The large number of facets also, more recently, allow for gem stones to be set alongside the diamond creating a distinctive piece with a range of colours and effects.

The emerald cut is popular amongst those looking for a vintage, art deco feel and a distinctive, square look.

Cushion Cut a Modern Choice

Many people see the popular cushion cut as a modern, technological advance. In fact the opposite is true. The vast majority of cut diamonds in the 19th century were cushion cuts and though replaced by the more technical cutting inventions the Cushion cut still appeals to those looking for a vintage or antique style.

Also known as the ‘Pillow’ or ‘Candlelight Cut’, the cushion cut was named as the rounded corners on the square or rectangular diamond resembled a cushion. The larger number of facets in the cushion cut allows for a high level of light dispersal and can give an appealing crushed ice look, which is widely sought after as an effect. The high number of facets also provides a wide spectrum of possible colours.

The cushion modified brilliant cut is created by adding an extra row of facets to the structure and this style has been known to reduce the shadowing from inclusions or flaws within the diamond itself.

Many of the world’s most famous diamonds and gems are cut in the cushion style to produce stunning colours and scintillating sparkle. For instance the Hope diamond, Regal diamond, Tiffany diamond and the Logan Sapphire are all cushion cuts. Indeed Tiffany have a cushion cut focus in their signature wedding ring range.

Many specialist designers can create great pieces from cushion cuts. Speak to a jewellery designer, such as online specialist DiamondGeezer.com for advice on the best cut for you.

Heart Shape for Romance

Of all diamond cuts and shapes the heart shape cut is the most symbolic. Though often associated with pendants and necklaces the heart shape cut is still rare in diamond design, making it all the more special for the recipient or wearer.

With an unknown history the heart shape cut came into fashion in the seventeenth century. A famous portrait of The Gonzaga Princess, by Frans Poubos in 1605 showed a prominent heart shape jewel at the centre of a cluster of precious stones. Later, in 1655, Jean-Baptiste Tavernier, a French author, documented seeing a 36 carat heart shape cut diamond in India.

In many cases the diamond was always seen as a heart shape, symbolising the romance of the object and gift.

Modern heart shape cuts are very fashionable and are seen in all forms of jewellery, including pendants, bracelets, necklaces and rings, especially engagement rings.

With a facet number of between 56 and 58 the sparkle of the diamond is directly linked to the quality of the curved cut and finish and designers have to be aware of the narrow “corners” of the cut, as well as the need to reduce the chance of the bow tie effect, or shadowing of the diamond.

For more information on the best cut for your diamond contact a design expert such as DiamondGeezer.com who provide a full design and manufacture service with a 30 day money back, or exchange guarantee, even on designed pieces.

Diamond Polish

DIAMOND POLISH

  • Diamond Polish and Symmetry are the two least respected attributes of a diamond – even by many jewellers who rarely make reference to them when presenting a diamond.
  • Quality of polish has a profound effect on sparkle.
  • The grading system appears to be a vague list of adjectives but is in fact a series of precise quality tags:
    • Ex = Excellent, ID = Ideal [Different terms used by different labs, they are the same quality]
    • VG = Very Good
    • G = Good
    • F = Fair
    • P = Poor
  • These quality codes define the finished surface of the diamonds facets.
  • Diamond polish can be compared to sanding wood, cutting meat or painting; there is a general direction and texture to be observed for excellence.
  • Expect to pay substantially more for a diamond with a quality polish.
