TORONTO, ONTARIO--(Marketwire - Feb. 16, 2011) - Crystallex International Corporation (TSX:KRY)(NYSE Amex:KRY) announced that it has filed a Request for Arbitration before the Additional Facility of the World Bank's International Centre for Settlement of Investment Disputes ("ICSID") against the Bolivarian Republic of Venezuela ("Venezuela") pursuant to the Agreement between the Government of Canada and the Government of the Republic of Venezuela for the Promotion and Protection of Investments (the "Treaty").

The arbitration has been commenced following the failure of the Venezuelan Government to propose any resolution to the dispute notified by Crystallex on November 24, 2008 and the subsequent unlawful termination on February 3, 2011, of the Mine Operation Contract ("MOC") it had entered into with Corporación Venezolana de Guayana ("CVG"). The claim is for breach of the Treaty's protections against expropriation, unfair and inequitable treatment and discrimination.

Crystallex seeks the restitution by Venezuela of Crystallex's investments, including the MOC, and the issuance of the Permit and compensation for interim losses suffered, or, alternatively full compensation for the value of its investment in an amount in excess of US$3.8 billion.
