De Beers Unveils Tool to Screen Multiple Set Stones

De Beers’ grading unit has developed the first synthetic-screening device capable of testing multiple jewelry-mounted stones at once without the need for a probe, the diamond producer claimed Tuesday.

The machine, called SYNTHdetect, only refers about 0.05% of diamonds for further checking, the lowest rate in the industry, according to the International Institute of Diamond Grading & Research (IIDGR). While other detectors come with an attached device that the user has to press onto each stone one at a time, SYNTHdetect lets the person place the jewelry on a tray so it can check all the stones at the same time.

IIDGR, a subsidiary of De Beers, unveiled SYNTHdetect at the JCK Las Vegas show this week. Using the laboratory’s patented luminescence technology, it can screen diamonds quickly and simultaneously in a range of jewelry pieces, including rings, earrings, bangles, brooches and necklaces.

The low referral rate significantly reduces the need for additional tests, which can be costly, IIDGR explained, pointing out that many other screening products send up to 10% of stones for further investigation.

IIDGR is taking orders for the machines — which are designed for back-office use among jewelry manufacturers and retailers — and said deliveries would begin in September. The launch follows IIDGR’s introduction last year of PhosView, which sifts out High Pressure-High Temperature (HPHT) synthetics. Earlier this year, it rolled out AMS2, an automatic melee-screening machine, which it will start delivering next month.

SYNTHdetect “will provide jewelry manufacturers and retailers with greater levels of assurance that every diamond they purchase and sell as a natural diamond is exactly that,” said IIDGR president Jonathan Kendall.
