It's called Connected Jewels and bills itself as the world's first mobile app capable of identifying pieces of jewelry by analyzing engraved serial numbers as small as 0.7 millimeters.

Designed to meet consumer expectations in terms of traceability , this feature allows for the detection of a unique and non-replicable code - discreetly - engraved on each piece of jewelry. The user can then access the product's digital passport to find detailed information on the origin of the materials, the manufacturing stages, as well as maintenance options and other exclusive content.
