PROBLEM: Diamonds have no immutable unique identification and no worldwide registration, accessible to the trade or to the general public. Only gemologists can currently certify diamonds. This extreme limitation has drastically reduced the availability of financing. Banks, insurance and transportation companies, pawn shops, and the general public have never been able to authenticate diamonds without the assistance of a diamond expert, therefore no trust. SOLUTION: Blockchain technology is THE enabler for the revitalization of an $80 billion USD diamond industry. By creating a uniquely coded and Blockchain registered identifier, each diamond will be traceable. Fraud risk will therefor be drastically reduced. We can now create a trustworthy marketplace for ancillary service providers and the general public. New diamond investment vehicles will therefore be created, which will generate the much needed liquidity in the marketplace.
