The GIA reports that rapid progress in the last few years in High-Pressure, High-Temperature (HPHT) technology is now being used to produce melee-size diamonds around 2–3 mm in diameter and large colorless single crystals all with significantly improved quality and growth rate.

I have been a strong proponent of generic diamond marketing. Fragmenting the diamond market with diamond brands is having a negative effect on the consumers’ perception of generic diamonds. Currently, we are not only witnessing diamond brand wars but a new war is developing involving diamond reports. De Beers is taking on the GIA by opening their grading facilities to the general trade and Martin Rapaport is taking on the world with his new Investment Diamond Report ... These reports, like branded diamonds, are harmful to the marketing of generic diamonds.
The Gemological Institute of America (GIA) has graded the largest polished blue synthetic diamond that the organization has ever examined.

The firm is one of the founding members of the International Grown Diamond Association which was launched earlier this month. The stone was inspected at the GIA's New York lab last month and received a fancy deep blue grade, according to a lab. The GIA published an exhaustive article on the stone's characteristics.
In a follow-up article to Chaim Even-Zohar's bombshell about CVD synthetic diamonds being sold on Alibaba with GIA natural diamond certificates, the Diamond Intelligence Briefing (DIB) identifies the name behind the fraud: Diwakar Dhyani.
"The Government of India should set up a regulatory authority to monitor the gemological laboratory business in India. The gemological laboratories issue only grading reports and no certificates. These laboratories have their own set of rules and regulations and even if consumers are cheated they have limited or no role to play. If a consumer has purchased a lab-grown diamond on natural diamond grading report, where will he go on being cheated? Who is responsible?
Alibaba, the leading e-commerce portal for global wholesale trade blacklisted and removed a New Delhi-based supplier of synthetic diamonds and gem simulants after it tried to sell lab-grown diamonds with fake Gemological Institute of America (GIA) natural diamond certificates.

"The diamond and jewelry industry is easy pickings", adding that, "We all recently saw the GIA get hacked. Is your security better than theirs?
Stella Layton, Chief Executive and Assay Master of the Assay Office Birmingham (AOB), spoke about diamond grading at CMJ’s UK Jewellery Conference last month: “It’s inconsistent – it’s based on subjectivity and there is a wide range of grading happening globally across diamonds, not just lab to lab but person to person.” Layton said that there is as yet no science that may be applied across the board to determine the exact grade of a stone, and even standard guides used to unify graders are open to interpretation.
Leading global gem labs and machinery manufacturers will exhibit their technology and equipment for the detection of synthetic diamonds at the Diamond Detection Expo & Symposium (DDES 2015) next month. There will also be seminars and panel discussions featuring experts and trade members.

The GIA said in a statement that just 175 of the 1,042 diamonds discovered to have had their grading reports changed in a hacking case by the lab's Indian sub-contractor have been returned for examination to the lab. It is imperative that all of the diamonds and their reports be returned to GIA for examination to remove the fraudulently altered reports from the market. The diamond trade must hold those who would commit such fraudulent acts accountable for their actions. The cooperation of the trade is vital as GIA works to fully address this fraud.
Mel Moss, president of Regal Imports Ltd., discusses his "terrible" buying trip to India, bemoaning the lack of well graded polished diamonds (particularly Canadian) and the "abundance of poorly graded GIA stones selling at discounts."

Rob Bates, JCK News Director, in his blog argues that the recent announcement by industry associations, saying industry professionals that carry reports that deviate by more than one color grade from the standard GIA scale will be subject to arbitration, could be a game changer. Overgrading has been a widespread trade practice, Bates says, and a dangerous one now that lawyers have announced they are intending to initiate a wider class action, targeting these malpractices.
