Shareholders are reminded that the rights offer circular can be downloaded from www.SEDAR.com where it was filed on February 4, 2010. Shareholders with questions are encouraged to call their stockbrokers if their Rockwell shares are lodged at a brokerage. Brokers should have received formal notification of the rights and they will automatically sell them on behalf of ineligible persons. Directly-registered shareholders should have received their rights in the mail, unless they are in the US. Questions can be directed to the Company at the phone number below and as well to Computershare, the depositary agent for the rights offering at Tel: 1-800-564-6253. The Company understands that there have not been significant enquiries from its shareholders who hold their shares on the JSE Limited in South Africa but, should any such shareholders have any queries, they may approach their brokers or at Computershare South Africa at Tel: 0861 100 933.

In other developments, the Company has signed a term sheet with Etruscan Diamonds Limited whereby the Company proposes to purchase Etruscan's Blue Gum diamond operation in the Ventersdorp region, South Africa. The acquisition is for 74% of the operation with the balance owned pursuant to South Africa's Black Economic Empowerment regime. The price to be paid to Etruscan is an amount not exceeding ZAR 33.5 million (approximately C$4.65 million) payable in Rockwell shares valued at C$0.068 each. The Company will also assume certain non-material property maintenance obligations effective immediately and other financial obligations upon completion of the acquisition.

The Blue Gum alluvial diamond deposit hosts estimated mineral resources of 25 million cubic metres (indicated) with a grade of 2.37 carats/100 cubic metres and 15 million cubic metres (inferred) with a grade of 2.37 carats/100 cubic metres as at October 2009.

Completion of the acquisition is subject to a number of conditions including South African mining ministry consent, securities regulatory approvals including TSX, satisfactory due diligence and project development financing and electric power negotiations. The Rockwell shares to be issued will be subject to escrow, resale and voting restrictions and will not materially affect control. Completion is targeted for the third calendar quarter.

     Information Concerning Estimates of Indicated and Inferred Resources

This news release also uses the terms 'indicated resources' and 'inferred resources'. Rockwell Diamonds Inc advises investors that although these terms are recognized and required by Canadian regulations (under National Instrument 43-101 Standards of Disclosure for Mineral Projects), the U.S. Securities and Exchange Commission does not recognize them. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. In addition, 'inferred resources' have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, or economic studies except for Preliminary Assessment as defined under 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
