       Gem Diamonds Australia declares offer for Kimberley unconditional





Further to the announcement by Gem Diamonds on 15 November 2007 of the decision
to extend the Offer Period from the previously indicated closing date of 23
November 2007 to 1 December 2007 for the cash offer for 100 per cent of the
issued share capital of Kimberley Diamond Company NL ('Kimberley'), Gem Diamonds
Australia, a wholly owned subsidiary of Gem Diamonds, has elected to declare its
takeover Offer for Kimberley Diamond Company NL ('Kimberley') to be
unconditional.



Gem Diamonds Australia has a holding of 14.92% in Kimberley's shares and has now
received total acceptances in respect of 66.59% (subject to the processing of
the institutional acceptances) representing a total relevant interest of 81.51%.
Gem Diamonds Australia will immediately begin processing acceptances for payment
in line with its undertaking to pay the consideration within seven days of the
Offer being declared unconditional.



As the majority shareholder in Kimberley, Gem Diamonds Australia representatives
will be appointed to the Kimberley board promptly after the close of the Annual
General Meeting of Kimberley shareholders to be held on 26 November 2007.   Gem
Diamonds will accordingly obtain management control of Kimberley from 27
November 2007.  A management team from Gem Diamonds will be in place at
Kimberley from this date.



Once Gem Diamonds Australia has acquired 90% of the issued shares in Kimberley,
it intends to compulsorily acquire the remaining 10% of the shares in issue and
delist Kimberley from the Australian Stock Exchange and withdraw its admission
to trade on AIM.  Gem Diamonds remains committed to achieving this in the
shortest possible time frame.



Definitions used in this announcement shall have the meanings given to them in
the shareholder circular posted 28 September 2007, except where context requires
otherwise.
