SSEF’s ASDI Achieves 100% Accuracy By DPA’s ASSURE Program

(PRESS RELEASE) BASEL, SWITZERLAND — The Automated Spectral Diamond Inspection (ASDI) device, an automated small synthetic diamond screener that was first released in 2014 by the Swiss Gemological Institute SSEF, has been evaluated by the ASSURE Program of the Diamond Producers Association (DPA) and proved to be one the few instruments to have successfully passed 100% of the tests administered. This means that all stones categorized by the instrument as “diamonds” were indeed natural diamonds, all diamond simulants were correctly sorted out, and all synthetic diamonds were correctly referred for definitive testing.

ASDI was built after a five-year R & D program at SSEF with the aim of protecting the Swiss watch and jewelry industry from being contaminated by synthetic diamonds, whose true origin is undisclosed. Every month, the industry consumes several million colorless small round polished diamonds, also known as melee.

When it was introduced in 2014, ASDI was the very first machine to automatically and efficiently screen large batches of colorless diamonds. Today, more than 20 different devices – automated and non-automated – are being offered by different producers, confirming that the pioneering vision of SSEF was in fact a necessity for the diamond trade.

The proliferation of synthetic diamond screening instruments in the market created a degree of confusion, particularly concerning each one’s capability, reliability and accuracy. To address the issue, in March 2019 the DPA, which is a body representing the world’s seven leading diamond mining companies, launched the “ASSURE Program,” an independent and international testing program that evaluates synthetic diamond screening instruments being offered in the market, and openly providing all test results on a dedicated website.

As part of the program, the ASDI system was subject to rigorous testing in May 2019 by an independent expert, UL Verification Services Inc., according to a very strict and standardized protocol. The testing sample was composed of 1,000 natural diamonds, 200 diamond-simulants and 200 synthetic diamonds, including stones created through HPHT and CVD, some of which were especially processed for the procedure. Although the ASDI can test stones as small as 0.85 millimeters (0.002 carats), the test sample was only composed of stones with a diameter ranging from 1.0 millimeter to 3.8 millimeters.

As the final test report indicates, the ASDI passed all tests with flying colors, unfailingly screening out every synthetic diamond and diamond simulant, operating at a speed of more than 6,500 stones per hour. The detailed report is available on the DPA’s ASSURE Program website.

The outstanding results confirm ASDI’s status as the preferred solution for the fast and extremely reliable screening of colorless diamond melee, especially in an industrial manufacturing environment such as the Swiss watch and jewelry industry.

“We are proud that ASDI was the very first such device available in the market to tackle the challenge of synthetic melees,” said Jean-Pierre Chalain, Director of SSEF’s diamond Department “We are thankful to DPA for its ASSURE Program initiative, as it has provided us the opportunity to demonstrate the capability of ASDI technology when it comes to automated small diamond screening.”

The ASDI system is still available and is being marketed by SATT Gems Ltd., a subsidiary of the Swiss Gemological Institute SSEF, one of the world’s leading gemological laboratories.

She Wanted to Spend More Time with Her Kids. She Called Wilkerson.

Your children are precious. More precious than gold? Absolutely! Just ask Lesley Ann Davis, owner of Lesley Ann Jewels, an independent jewelry store that — until the end of 2023 — had quite a following in Houston, Texas. To spend more time with her four sons, all in high school, she decided to close her store. Luckily, she was familiar with Wilkerson and called them as soon as she knew she wanted to move on to bigger, better and more family-focused things. Was she happy with her decision? Yes, she was. Says Davis, “Any owner looking to make that life change, looking to retire, looking to close, looking for a pause in their career, I would recommend Wilkerson. Hands down!”
