Dear Borden,

         We are pleased to confirm your acceptance of permanent employment with
Crystallex International Corporation effective September 1, 2002 and your
appointment as Chief Financial Officer of the Company. Your salary for the
balance of the 2002 calendar year will be Cdn $10,000 per month, payable monthly
in arrears, effective September 1, 2002. Effective January 1, 2003, your annual
base salary will be increased to Cdn $265,000 payable in equal monthly
installments in arrears. We confirm that you will devote a minimum of four days
per week to the business of the Company. We also confirm that any other source
of employment, or consulting arrangements which you might undertake, will not be
in conflict with the business or interests of the Company and will not prevent
you from attending to the business of the Company as herein provided. You will
immediately assume the duties of Chief Financial Officer and will direct the
financial affairs of the Company including liaison with senior management, the
Audit Committee and the Board of Directors. You will also direct the development
of the Company's financial and reporting systems in Venezuela, Uruguay, Canada
and the USA including compliance with increased reporting responsibilities
arising from recent revisions in applicable legislation in Canada and the USA.
You will report directly to Marc Oppenheimer, our President and CEO, and both
Bob Crombie and KY Sze Tho will work under your direction as VP-Finance and
VP-Accounting respectively. We would expect you to work closely with senior
management and the Board in developing and continuing our relationships with our
bankers, investors and potential investors and in developing and presenting
financial and related proposals of the Company.

        At present, the Company does not maintain a benefit program in Canada.
As you know, however, we are in the process of investigating benefits for our
employees as we reach numbers appropriate to support a benefit program in
economic terms. The Company would be pleased to extend to you and your family
any benefit package which might ultimately be

arranged. All expenses of employment supported by receipts or comparable
evidence of payment will be reimbursed by the Company.

        The Company has a discretionary bonus program based upon Company and
individual performance. Bonuses are paid annually in the discretion of the
Board, upon the recommendation of the Compensation Committee, after input from
senior management. Payment is anticipated late in the Company's fiscal year and
you will be included in these bonus deliberations for the 2002 fiscal year.

        The Company has an employee incentive option plan for which you will be
eligible. Option grants are in the discretion of the Board, again, upon the
recommendation of the Compensation Committee and senior management. Options are
generally considered at the end of the fiscal year. You will be considered an
insider of the Company and you will be required to complete requisite insider
filings with appropriate regulatory agencies. An initial filing will be
required immediately upon the issuance of shares to you and additional filings
are required within ten days of the grant or exercise of options and the sale or
purchase of shares of the Company.

        The Company has initiated a program of compensation continuance in the
event of a take-over or sale of the Company or substantially all of its assets
which results in the termination of employment. The program is designed to offer
limited protection to employees in circumstances where employment is
unexpectedly curtailed. We confirm that, for your employment only, the
compensation continuation period will be two years.

         Recognizing that your employment is less than full-time, your vacation
entitlement during each fiscal year will be 15 days, and while every attempt
will be made to accommodate vacation schedules, we would request that you not
schedule vacation at critical reporting periods. Your vacation period will be
prorated until year end. Given the nature of our business we do not have fixed
business hours or a fixed work week. There will be significant travel involved
in your employment, notably in Uruguay and Venezuela. I would request that you
check your immunization record to be sure that you have received all recommended
immunizations for travel in South America. A passport will be required for
travel to South America.

        During your employment with Crystallex International Corporation, or at
any time thereafter, you shall not divulge, communicate or use any confidential
information which you may have access to or otherwise receive or obtain in
relation to the affairs of the Company or any of its subsidiaries, related
companies of affiliated entities. Confidentiality is of utmost importance to our
Company in an obviously highly regulated environment. Breach of confidentiality
will be considered cause for immediate dismissal.

        In the absence of cause, employment can be terminated by either party
upon three months written notice or by the Company immediately upon payment of
cash in lieu of notice. Your convenant of confidentiality will survive
termination.

        By signing and returning a copy of this letter, you agree to all of the
conditions noted above and you agree to become familiar with, and abide by, all
Company policies regarding business conduct, securities trading, operating
procedures and health and safety throughout your employment with us.

        It is my great pleasure to welcome you to our management team. You are
joining the Company at an exciting time and I am sure that the Company will
benefit immediately from your wealth of experience.

                                      Yours very truly,

                                      Crystallex International Corporation


                                      /s/ Marc J. Oppenheimer

                                      President & CEO

AGREED AND ACCEPTED
