Crystals are isometric and predominatly octahedral.
Exploration of these kimberlite pipes is being undertaken by several companies. The Fort a la Corne Diamond Project covers 25,488 hectares of claims and includes 71 known kimberlite pipes. The largest diamonds recovered to date are 0.985 and 0.275 carats. The smaller macrodiamond is clear and white and may be a fragment of a larger stone. The geology of these pipes is unique in the world as they are covered by a thick sedimentary layer deposited by an ancient inland sea.
