Diagem Receives the GIA Grading Report on its 3.07 Carat Pink Diamond

MONTREAL, QUEBEC--(Marketwire - Nov. 13, 2007) - Diagem Inc. ("Diagem" or "the Company")(TSX VENTURE:DGE) has received from the Gemological Institute of America ("GIA") the grading report (the "GIA Report") on its cut and polished 3.07 carat heart-shaped diamond. The GIA Report stated that the diamond colour is a Fancy Orangey-Pink with an even distribution and a clarity grade of SI2 (Slightly Included 2). The GIA graded both the polish and symmetry of the diamond as Very Good.

The GIA laboratory determined the 3.07 carat diamond to be a rare type IIa pink diamond. Reportedly less than 2% of all gem diamonds fall into the type II category. Type II diamonds contain little if any nitrogen, often have relatively few inclusions and are noted for their mostly homogenous color in the rough.

Denis Francoeur, CEO of Diagem Inc, stated "The grading report from the GIA is additional evidence that the Juina area, and more specifically the Chapadao cluster, is capable of producing extremely rare and valuable diamonds".

The diamond was originally a rough 9.32 carat diamond when recovered by artisanal miners less than three kilometres downstream from Diagem's Chapadao cluster of kimberlites that were discovered in late 2006. Diagem purchased the diamond to demonstrate the potential of Chapadao kimberlites. The Company has also documented the recovery of other pink diamonds by artisanal miners in the area surrounding the Chapadao cluster.

The GIA report indicates that, unlike many other coloured diamonds, the color in the Type II pink diamonds can not only be caused by impurities, but it may also be a result of the diamond's exposure to heat and pressure during transportation into the Earth's crust. This corroborates the observations of Dr. Felix Kaminsky, 2001, in a publication entitled "Super Deep Diamonds from the Juina area, Mato Grosso State, Brazil".
