June 28, 2007 Vancouver, B.C. -- Rockwell Diamonds Inc. ("Rockwell" or the "Company") (TSXV: RDI; OTCBB: RDIAF) reports on its diamond tender sales completed on June 27, 2007 for the Wouterspan, Holpan and Klipdam operations west of Kimberley, South Africa.
The average price achieved by the Company for the sale was US$1,888 per carat as shown in the table below. The parcel of diamonds tendered included 26 stones greater than 10 carats in weight, with the largest a 48.15 carat stone from Wouterspan on the Middle Orange River ("MOR").
Consistently high prices were received for diamonds from all three of the Company's operations, with strong demand and excellent US Dollar per carat values being achieved for stones larger than 3 carats. Prices for goods below 3 carats were slightly softer than in previous tenders of 2007, though better than reserve prices were achieved on the majority of these goods.

Wouterspan production included six stones between 10 to 20 carats, two stones between 20 and 30 carats, and one stone in the 40 to 50 carat size range. Holpan production included three stones in the 10 to 20 carat range, two stones in the 20 to 30 carat range, and two stones in the 30 to 40 carat range.
Klipdam production included seven stones in the 10 to 20 carat range, two stones in the 20 to 30 carat range, and one stone in the 30 to 40 carat range.
At the new Makoenskloof project, located upstream of Wouterspan on the MOR, the recovery plant is undergoing commissioning Screened gravel is being processed at low rates of throughput while key plant components are tested and synchronized prior to proceeding to routine production. A large stockpile of screened gravel has been created from mining a thick sequence of gravel that was encountered less than 300 metres to the north-west of the processing and recovery plant in an area designated for the construction of a tailings disposal facility. The in-situ gravel has now been removed and forms the majority of the screened stockpile, and the tailings disposal facility has also been completed.
President and COO John Bristow noted that "the June production and tender results are particularly satisfying in respect of diamond recoveries achieved for a 29-day period spanning May and June, the overall quality of goods recovered from all the mines, and the outstanding average US Dollar prices achieved from all three operations. Extra effort devoted to the make-up of diamond parcels sold on the tender has also been positive as we have achieved better overall higher results from the sale."
