Eternity Diamond’s certificate is issued following an unbiased and professional examination to authenticate a diamond’s attributes. The carat weight, colour and clarity are all recorded on the certificate and the natural inclusions are also indicated on a diagram of the diamond: this is called diamond plotting. The certificate also shows the diamonds exact measurements in both mm size and percentages.
A Diamond Certificate will also indicate the cut of the diamond. Cut is particularly important as it determines the brilliance and radiance of the stone.
The overall quality of cut is determined by the combination of ‘Cut Proportion’, ‘Cut Symmetry’ & ‘Polish’. Together the three describe the overall cut of the diamond.
– Proportion refers to the measurements of the facets, the number of facets & the diamonds overall dimensions.
– Symmetry refers to the alignment and balance of the facets.
– Polish refers to the overall finish of the surface of the diamond.
All Eternity Finely Cut Diamonds will show a minimum of ‘very good’ or ‘excellent’ in ‘cut proportion, ‘cut symmetry’ and ‘polish’.
All Eternity Hearts & Arrows Diamonds will display ‘excellent’ in all three areas. A diamond of this quality is sometimes referred to as ‘Triple Excellent’.
Are all Diamond Reports the same?
An unbiased, independent diamond certificate is the most important element when selecting a diamond. An Eternity Diamond certificate guarantees and stands behind the quality of the graded diamond giving you the confidence to make that very special diamond purchase.
Not all certificates are the same.
For example the Gemmological Institute of America (GIA) state the following on their report:
“This Report is not a guarantee, valuation or appraisal, and the laboratory providing this report (GIA) has made no representation or warranty regarding this Report, the diamond described herein or any inscription thereon”.
The GIA have many grading laboratories worldwide which makes consistent quality control difficult. We have seen this recently with a wide recall on incorrect GIA Diamond Reports. Coupled with the fact that the GIA will no longer provide you or your client with a reprint should your ‘Diamond Report’ be lost or damaged, the value of a GIA Report has become seriously degraded.
However, as some of our markets demand GIA certified goods we do have GIA certify a percentage of our Eternity Diamonds. All GIA certified diamonds are then independently recertified by the Australian Diamond Grading Laboratory in Australia to ensure they comply with our strict regulations of grading, and to offer our unique customer guarantee.
Certification or Branding?
Diamond certificates are great for documenting the colour, clarity and carat weight of your diamond. They are not so helpful when it comes to the effects of fluorescence on the look of the diamond or the type or placement of the internal inclusions. These characteristics are difficult to document and further adds to the risk of buying an unseen diamond online.
It is also important to understand the term ‘cutting to certificate specifications’. The majority of white diamonds are cut according to computer specifications. These specifications can be altered and set up to the user’s preference. It is considered normal for different gem labs to have different specifications or rather ‘wider set’ specifications that identify a stone as ‘excellent’ or ‘very good’ for example. In other words one laboratories ‘excellent’ may only be considered ‘very good’ by another.
This variation in specs from one lab to another can possibly degrade a diamond certificates usefulness in defining cut. ‘Cut’ is one of the most important elements in ensuring a high quality radiant diamond.
Diamonds that look good on paper but not when you see them are often referred to as ‘Certificate Pretty’ stones. This is where diamond branding becomes important. A branded diamond has its own built in quality control. With a minimum of VG for Finely Cut and EX for Hearts & Arrows, individually selected and independently graded, an Eternity Diamond is a no risk purchase and a guarantee of exceptional quality.
