Stuller Inc Adding Screening Devices To Deal With Lab-Grown Diamonds

(IDEX Online) – Jewelry-maker Stuller Inc is introducing additional screening measures at its facilities to deal with the rise in undisclosed lab-grown diamonds.

“The introduction and rise of lab-grown diamonds makes reliability and trust more important than ever,” says Stanley Zale, vice president of diamonds and gemstones. “We started introducing more screening steps through the use of machines like the De Beers Automated Melee Screening Device for stones we bring in-house. Now, not only have we added more technology for even better screening, but we’ve also made that technology available for our customers to use in their stores.”

This year, Stuller will add these new and improved screening devices to its newly established Diamond Lab:

• The De Beers Automated Melee Screening Device 2, which provides an increased processing capacity of 3,600 diamonds per hour

• Three advanced analytical spectrometers – Raman & PL, FTIR, and UV-Vis-NIR

• The De Beers’ PhosView®, a self-contained screening device

• The portable D-Screen machine from HRD Laboratories

• The Presidium® screener

“This cutting-edge technology coupled with many years of experience has evolved our first ever diamond-screening laboratory – a one-of-a-kind center solely focused on ensuring diamond integrity,” said Zale. “We don’t tolerate undisclosed lab-grown diamonds in our inventory. For added security, we further require our vendors to screen all diamonds for lab-grown. Random samples of stones are also periodically sent out to leading laboratories to check for synthetics.”

Stuller said that it is also offering more than 15 different testing machines in all price ranges to jewelers interested in acquiring them to test diamonds in their stores.
