Canadian Firm Develops Fingerprinting
To Fight Conflict Diamond Trading - Feb.2001
Canada’s CVF Technologies Corp. claims to have developed a system to
"fingerprint" diamonds from mine to consumer in an attempt to thwart
sales of conflict stones.
The system uses a laser to identify unique light patterns from a cut stone and
downloads the information onto an international database. The fingerprinting is
already being used on diamonds from the Ekati mine in Canada‘s
Northwest Territories.
While many laser-inscription services have been developed, CVF Technology
emphasizes that their technology is not an erasable imprint but, rather, an
invisible process of identifying a cut stone by its light patterns--patterns
that can not be erased without extensive recutting of the stone.v |
