Crystallex Receives Delisting Notification From NYSE Amex

   Crystallex International Corporation (TSX: KRY)(NYSE Amex: KRY) (the "Company") has received notice, dated April 5, 2011, that the NYSE Amex LLC (the "Exchange") intends to proceed with an application to the United States Securities and Exchange Commission (the "SEC") to remove the Company's common shares from listing on the Exchange. This determination, which the Company intends to appeal, was made in light of the Exchange staff's position that the Company is not in current compliance with certain standards for continued listing on the Exchange set forth in Part 10 of the NYSE Amex LLC Company Guide (the "Company Guide").

Specifically, the Exchange staff believes that the Company is not in compliance with (i) Section 1003(c)(i) of the Company Guide on the basis that the Company has "substantially discontinued the business that it conducted at the time it was listed or admitted to trading" with the Exchange, and is no longer an operating company for purposes of continued listing on the Exchange, and (ii) Section 1002(c) of the Company Guide, which states that "the Exchange, as a matter of policy, will consider the suspension of trading in, or removal from listing or unlisting trading of, any security when, in the opinion of the Exchange the issuer has sold or otherwise disposed of its principal operating assets, or has ceased to be an operating company".

The Exchange staff has made this determination based on information disclosed by the Company in its Annual Information Form for the year ended December 31, 2010, dated March 31, 2011 (which forms a part of the Company's Annual Report on Form 40-F). Specifically, the Exchange staff referred to events surrounding the termination of the Company's Mine Operating Contract (the "MOC") by the Corporacion Venezolana de Guayana on February 3, 2011 because of the lack of progress to the Las Cristinas Project for more than one year and for reasons of "opportunity and convenience"; the Company's filing of a request for arbitration against Venezuela before the Additional Facility of the World Bank's Centre for Settlement of Investment Disputes, which is currently pending; the Company's commencement of an orderly handover of the Las Cristinas Project including, but not limited to, the security for the site, personnel and social projects; and the fact that the Company's main asset is the pending arbitration, and that no other properties are currently owned or operated by the Company and mine exploration has ceased. The Exchange staff also noted that over the last 30 trading days, the price per share of the Company's common shares has averaged US$0.15 per share and as of April 1, 2011, it closed at US$0.16 per share. Based on this low selling price, along with the information referred to above, the Exchange staff believe that the Company's common shares are not suitable for continued listing.

In accordance with Sections 1009(d) and 1203 of the Company Guide, within seven calendar days of the date of the receipt of the notice from the Exchange, the Company plans to appeal the Exchange staff's determination by requesting an oral hearing before a Listing Qualifications Panel. There can be no assurance that the Company's request for continued listing following the appeal will be granted.

The Company reasonably believes that there is value in the Company and is continuing to take steps to seek, through the arbitration process, full restitution by Venezuela of its investments, including the MOC, and the issuance of the Authorization to Affect Natural Resources permit from the Ministry of Environment and Natural Resources 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. While pursuing the arbitration claim, the Company is continuing to seek settlement alternatives with the government of Venezuela, which would result, if completed successfully, in value to the Company's stakeholders. The Company's common shares will continue to trade on the Toronto Stock Exchange and will recommence trading on the Exchange while the Company's appeal is pending. The Company will continue its normal course of business operations notwithstanding the status of its Exchange listing.
