De Beers Rolls Out XL Version of Lab-Grown Screening Device
The SynthDetect XL allows for more jewelry to be screened at once, the International Institute of Diamond Grading & Research said.

London—The International Institute of Diamond Grading & Research has introduced SynthDetect XL, an advanced version of the SynthDetect screening device.
IIDGR, which is the De Beers Group’s lab, introduced the SynthDetect machine last year, calling it the first screening device for man-made diamonds that can test multiple stones in set jewelry at once.
It uses IIDGR’s patented luminescence technology to screen diamonds of all sizes in rings, earrings, bangles, brooches and necklaces.
Now, IIDGR unveiled a new version of the machine at the recently concluded Hong Kong Jewellery & Gem Fair.
SynthDetect XL has a larger base unit that allows for more jewelry to be screened simultaneously, like larger necklaces, multiple solitaire rings and multiple bracelets.
The new version still uses the detection techniques for identifying natural (mined) diamonds developed for the original SynthDetect device, meaning if a stone in a piece of jewelry doesn’t display the attributes of a natural diamond, it is highlighted immediately and with a high degree of accuracy.
De Beers did not respond to an email by press time inquiring about the machine’s availability and pricing. (The original SynthDetect costs $16,250.)
“We’re delighted to be introducing the next innovation in IIDGR’s range of industry-leading synthetic screening devices, SynthDetect XL,” IIDGR President Jonathan Kendall said. “Using the same revolutionary technology as the original SynthDetect, this new device allows more pieces of jewelry to be screened at a faster rate than ever before. SynthDetect XL will be another valuable tool for the trade, building on the strong positive feedback we’ve received since launching the first SynthDetect last year.”
