This New Technology Sniff Out Diamonds With Counterfeit Inscriptions

PhotoScribe Technologies was awarded a patent for new technology.

PhotoScribe Technologies has been awarded a patent for new technology that will let jewelers and consumers sniff out diamonds with counterfeit inscriptions. PhotoScribe’s solution—called the Unique Secured Product ID—involves overt security features as well as covert ones.


PhotoScribe Technologies has been granted a patent for innovative technology that will allow jewellers and customers to detect fake writing on diamonds.

“There have been several cases of diamonds with forged inscriptions,” says PhotoScribe CEO David Benderly. “People have recently grown more adept, inscribing synthetic diamonds and passing them off as genuine diamonds with the same characteristics.”

He claims that these forgeries can mislead any but the most skilled gemologists.

“Because GIA gathers hundreds of data points for each diamond, they have little trouble detecting if a diamond is [related to the report].” However, the ordinary business owner may be unable to recognise it.”

PhotoScribe’s solution, known as the Unique Secured Product ID, combines overt security elements, such as the regular PhotoScribe inscription, with covert ones, such as an invisible bar code that can be read by a special app.

‘It’s just another layer of protection for jewels,” Benderly explains. “Security is constantly multilayered. It’s like a dollar bill—always there’s more than one thing—the colour, the watermark. This provides the consumer a means to check the diamond.”

He prefers that the distinguishing security feature originate from the diamond itself: “It might be an inclusion in the diamond or a certain diamond junction or facets that we recognise.”

PhotoScribe revealed last year that it has invented a “subsurface” writing for diamonds that cannot be cleaned off.


A diamond inscription is a series of letters and numbers carved into the stone, often on the girdle. These symbols serve as a unique identification that, if necessary, may be used to identify a certain stone. Inscriptions help you differentiate your diamond from other stones.

Because some producers decide not to pay for inscription services, not all diamonds on the market are laser inscribed. You may, however, have your stone etched for an extra charge. Grading laboratories that adhere to international standards will not affix a certificate number to a diamond.

A gem loop is the sort of equipment you will need to inspect your gi laser inscription. Or a microscope, because it’s really little and difficult to see.

Billionaire Laurence Graff paid a record-breaking $46.1 million for a magnificent vivid pink diamond weighing 24.78 carats. Originally owned by his competitor Harry Winston, it now carries graff’s name and is a part of the legendary collection of rare diamonds.

We usually advise brilliant round diamonds with a cut grade of very good, ideal, or super ideal for engagement rings (also known as hearts and arrows). A high cut grade maximises a diamond’s beauty for a given carat weight.


It’s crucial to have a concept of what you might prefer before starting your search because it will enable you to focus on fewer of the many engagement ring possibilities that are now available. Also, when you initially start browsing, it helps to have a few distinct design concepts and the overall budget because the variety can be overwhelming.

Here are Engagement Ring Trends 2023:

1. Modern Art-Deco
2. Colored Stones
3. Lab-Grown Diamonds
4. East-West Settings
5. Multiple Large Stones
