Crystallex International Corporation (TSX:KRY)(NYSE Amex:KRY) announced today
that it has completed its previously announced financing of 70,000,000 units
(the "Units") at C$0.50 per Unit (the "Offering Price") for

The Company has granted the Underwriters an over-allotment option to purchase
up to an additional 10,500,000 Units and/or up to an additional 5,250,000
Warrants, exercisable at any time prior to the date that is 30 days following
the closing of the offering. If this option is exercised in full, the gross
proceeds to Crystallex would increase to C$40,250,000.

Crystallex intends to use the net proceeds from the offering for Las Cristinas
project related expenses, debt service and for general working capital purposes.
