Harry Vos first cut the diamond into an emerald shape weighing 143 carats, but when a flaw was noticed in the gem's interior, it was re-cut into 17 different diamonds, 13 of which have been declared to be flawless in quality. Harry Winston chose to take six of the resulting diamonds and forge them into a single brooch, which was dubbed the "Star of Sierra Leone" brooch. Of the 13 flawless fractions from the original harvested diamond, the largest was polished into a pear shape weighing just under 54 carats.
