PhotoScribe Granted Patent for Method that Verifies a Stone’s Identification

The secure mark combines an overt mark with a covert data set to provide assurance on a gem.

PhotoScribe Technologies has secured a patent for its method of ensuring the correct identification of a stone using an overt mark, like a bar code, and a covert data set from the gem itself.
New York—Diamond inscription innovator PhotoScribe Technologies has secured a patent for its method of ensuring the accurate identification of a gem.

The Unique Secured Product ID (USPID) patent uses a secure mark to validate if a diamond matches what it is said to be, PhotoScribe said.

Each secure mark has two components, the first being an overt mark on the stone, such as a bar code, serial number, or logo.

The second component is a covert data set, which is a data set that cannot be seen or recognized as a part of the code but comes from the specific stone.

For example, a barcode may lead to the coordinates of an inclusion unique to a diamond or decipher if an inscription is the correct distance from a specific facet junction or position on the girdle.

The covert data set is unique for each diamond, regardless of whether it’s natural or lab grown.

By using both overt and covert, a diamond can be verified or a forgery easily identified—if the data sets don’t match the original data for a stone, it cannot be authenticated. 

CEO David Benderly told National Jeweler the company has two methods for storing the data—online and offline.

In the former, the data is verified in the cloud against a pre-stored database.

The latter method uses an offline self-verifying code that doesn’t rely on a pre-stored database or require an internet connection. 

“My goal is to promote trust in our industry by eliminating forgeries and giving consumers peace of mind,” Benderly said in a press release. “A secure product identification helps consumers and businesses make informed purchasing decisions because they can trust that the products they buy are genuine.”

Photoscribe also noted its signature laser system, the LMS-650, can be upgraded to allow the secure mark technology to be brought in-house so labs and trade businesses can guarantee the identification of a stone through its journey.

For a gemstone identification not generated by a PhotoScribe laser, the company said it will provide software-only solutions that use its algorithm and database.
