Authentication and Identification with


Optical fingerprinting with DiamondMatch™ imaging algorithm

The pioneering application of optical imaging technology, using high resolution telecentric lenses and algorithms, that enable the unique fingerprinting of polished diamonds and subsequent quick identification anywhere in
the supply chain.




A diamond is fingerprinted (or registered) and
accociated, linking it permanently to its report.
Later the diamond is verified (or authenticated)
to its grading reports using DiamondMatch™

The leading deployment of optical imaging technology with telemetric lenses and algorithms that allow unique fingerprinting of product and subsequent rapid identification when required anywhere in the supply chain.



Spacecode’s DiamondMatch™ facilitates the registration (fingerprint), identification and authentication (DiamondMatch™) of loose diamonds.

The key component of the physical device is a high-resolution camera
with telecentric lenses for table analysis of a polished diamond.

DiamondMatch™ uses a proprietary algorithm which creates a unique fingerprint for each diamond based on the image of the diamond table.

DiamondMatch™ software offers a user-friendly interface to facilitate the process.

Using DiamondMatch™ anyone can then identify and verify the authenticity of a diamond and its grading report.


DiamondMatch™ boosts multiple supply chain phases

For grading laboratories, sales offices, and retail locations, DiamondMatch™ offers precision technology for authentication and verification of diamonds forever linking them to their
grading reports.

DiamondMatchis used by companies for audits, insurance, banking, authentication, and track & trace from one location to another.

DiamondMatch prevents fraud by providing a unique reference linking a diamond to its grading report specifications.

DiamondMatch grading labs can register a diamond and its certificate in their database, allowing anyone in the supply chain to link the certificate to the diamond.

DiamondMatch is noninvasive and eliminates the requirement to laser engrave the report number into the girdle of the diamond.

DiamondMatch provides complete security and status.

DiamondMatch offers operational control and professional efficiency.
