Basel, Switzerland--The Swiss Gemmological Institute SSEF has introduced a new system for scanning single and multi-strand pearl necklaces.

Developed in collaboration with CSEM (the Swiss Center for Electronics and Microtechnology), PearlScan counts and measures large quantities of pearls on strands in relatively short periods of time using an A4 scanner, computer and proprietary software.
The software uses a complex algorithm to detect different strands and count the pearls while also measuring the diameter of each one and distinguishing them from other elements like knots, diamonds and other decorative items. It also calculates a roundness factor for every pearl and measures the length of each strand.

The system is semi-automatic, allowing for user intervention to optimize and review output.

PearlScan produces images and detailed reports of the number and diameter of each pearl on the different strands.
SSEF unveiled the system during the Baselworld show.

PearlScan costs $9,900 and will be sold through SSEF subsidiary SATT Gems SA.

“We have found that PearlScan greatly supports analytical and documentation procedures in our own laboratory at SSEF. We are glad to be able to offer now this new and easy-to-use solution to the trade and pearl industry,” SSEF Director Michael S. Krzemnicki said.

Editor’s Note: This article was updated on March 30 to add in the price of the PearlScan machine, which was given to National Jeweler after the story was published.
