Myths, Facts, and Realities

DUBAI, UAE, November 13 — Gemological Science International (GSI) is pleased to announce that they will be presenting a seminar entitled “Man-Made Diamonds – Myths and the Facts – Realities” to interested parties at the DMCC Dubai on 20th November Monday at 9.00 a.m. The presenters are Ms. Seema Athavale, Chief Gemologist – GSI, and Mr. Nicholas Del Re, Chief Information officer –  GSI. The seminar is intended to educate the audience as to the growth of man-made diamond manufacturing and to discuss ways in which this interacts with the other components of the trade, in particular, the natural diamond jewelry industry, and how these interactions can be successfully managed.

The reality is that synthetic diamonds are rapidly coming of age quality-wise in comparison to even the best natural stones. As a result, increasing numbers of man-made stones are mixing with natural products in the supply chain. Where this is being done in an aboveboard manner is not a problem, but there is a rising amount of synthetic diamond being surreptitiously introduced into certain product lines such as diamond-set jewelry where it is not economical to test every single stone.


Although not yet of serious proportions, the continued introduction of synthetic diamonds into the retail jewelry trade, if allowed to continue on an undisclosed basis, is likely to lead to one or more severe crises bringing about a potential public collapse in confidence as to the value and ability to resell these mixed sets. While there has always been some small measure of various forms of undisclosed diamonds in industry, the traditional tracking methods have, thus far, proven sufficient to maintain a general belief in diamonds as both an object of rare beauty and as an investment. It is clear, however, that new procedures in verification as to the origin and type of diamond are going to be needed.

In particular, everyone in the industry needs to start pro-actively cooperating on finding new policies and procedures that will prevent this topic from becoming a subject of general public awareness. With the possible exception of various criminal enterprises, it is in nobody’s interest to degrade standards and deceive the public as to the value of their purchases.

As a certified full-service lab for the global diamond and colored stone trade, GSI believes it is important for everyone in the industry to understand what new tools for verification are currently available and which ones are nearing the end of their beta testing phase. While new administrative and tracking procedures are certainly a part of the solution, greatly improved test equipment would go far in finishing the job as well and highly skilled research and development will be needed, but the industry needs to be made aware of what tools are available and how important it is for them to be deployed on an essentially universal basis.


The final consumer of all diamond products must rest fully assured that the items they purchase are accurately labeled and graded. The only way to achieve this is through an industry-wide commitment to the proper classification of man-made stones and impossible-to-evade safeguards that will catch any and all attempts at circumventing these procedures. Seminar attendees will leave with a superior understanding of all these underlying factors as well as get an early look at all of the new verification measures designed to provide accurate and swift classification in a low-cost manner.

GSI is headquartered in New York, NY. It has 13 laboratories on four continents and in a number of countries: the United States, India, Dubai, Israel, Belgium, Hong Kong, and Botswana. This makes GSI one of the largest independent gemological organizations in the world.

Is there a difference between grading reports issued by different GSI laboratories?

What does it mean when a sales associate tells me my diamond is “GSI Certified” or is accompanied by a “GSI Certificate”?

The phrases “GSI Certificate” and “GSI Certified” are industry shorthand for GSI grading or identification reports. What this means to you is that expert gemologists and trained professionals meticulously evaluated the item. When your diamond, jewelry or gemstone is accompanied by a GSI grading report, you can be completely confident in the accuracy and objectivity of the evaluation.

Where can I find “GSI Certified Diamonds”?

GSI diamond grading and identification reports can be found in jewelry stores worldwide and online. Insist on a GSI grading report when shopping for a diamond, jewelry or gemstone.

What are the 4Cs

A beautiful diamond is one of nature’s most mesmerizing creations. But how do you objectively judge the quality of the gem? The 4Cs – Cut, Color, Clarity, and Carat Weight – are the universal standard for doing this.

Is there anything beyond the 4Cs?

The 4Cs are an essential and important description of a diamond’s characteristics. But there is a considerable amount of detailed information behind each “C” along with other qualities of a diamond that affect its beauty, such as fluorescence, light performance and more.

How much do you need to know? That’s up to you, but knowing the 4Cs is almost essential.

What does a GSI colored diamond grading report look like?
