For Immediate Release

TORONTO, ONTARIO, December 30, 2005 – Crystallex International Corporation (TSX: KRY) (Amex: KRY) announced today that it has acquired the minority shareholder interests in the holding companies which own or control the mining rights to certain of its Lo Incréible mining properties located in Bolivar State, Venezuela (including the La Victoria deposit).  Crystallex also announced that the outstanding arbitration proceedings between Crystallex and Corporacíon Vengroup, S.A. have been settled.

Under the terms of the transaction:

• ECM (Venco) Ltd. (an indirect, wholly-owned subsidiary of the Crystallex) has purchased the 49% outstanding interest in Osmin Holdings Limited and the 30% outstanding interest in Tamanaco Holdings Limited owned by Vengroup and a related company for consideration consisting of U.S.$6.6 million payable as follows:
o U.S.$3.0 million, by the issuance and delivery to Vengroup of 1,467,136 Crystallex common shares; and
o U.S.$3.6 million, by the issuance and delivery to Vengroup of a U.S.$3.6 million exchangeable promissory note of ECM; and
• the arbitration proceedings between Crystallex and Vengroup have been terminated and the parties have delivered mutual releases with respect to the subject matter of the arbitration proceedings.

The exchangeable promissory note is non-interest bearing and payable in four equal semi-annual instalments commencing June 29, 2006.  Vengroup may elect to exchange the instalment payments for, and ECM may elect to satisfy its obligations to make instalment payments by, delivering Crystallex common shares.  The number of Crystallex common shares to be delivered to Vengroup will be based upon the weighted average trading price of the Crystallex common shares on the Toronto Stock Exchange during the five trading days immediately preceding the delivery of an exchange notice by Vengroup or ECM.

As a result of the transaction, the joint venture arrangements between ECM and Vengroup have been terminated and Crystallex, through its subsidiaries, now owns 100% of Osmin and Tamanaco. ECM’s obligations under the exchangeable promissory note are guaranteed by a subsidiary of ECM and secured by a pledge of the shares of ECM’s Venezuelan subsidiary that directly owns the principal Lo Incréible mining properties held by ECM. As part of the transaction, Crystallex entered into a two-year consulting agreement with the principals of Vengroup pursuant to which Crystallex has agreed to pay aggregate consulting fees of US$600,000.
