The "Star of Sierra Leone"is the largest diamond to be discovered in the alluvial deposits of Sierra Leone. The diamond is a colorless, lustrous and pellucid crystal, features that are so characteristic of the exceptional quality colorless diamonds found in the country. The name Star of Sierra Leone appears to have been inspired by the lustrous nature of this enormous crystal.

Characteristics of the diamond

The rough diamond was an enormous colorless and transparent crystal weighing 969.8 carats, which was subsequently cut into 17 stones, 13 of which were flawless.

The largest stone that was cut from the diamond weighed 143.20 carats originally, but was flawed. To eliminate the flaws the stone had to be re-cut again, with a drastic reduction in weight, resulting finally in a pear-shaped, colorless, and flawless, 53.96 carat diamond.

Diamonds of Sierra Leone have an international reputation as one of the highest gem quality diamonds in the world. The diamonds are so pure and free of inclusions, that some of them are known as "glasses", clear, transparent and absolutely colorless. Even though the diamonds derived from the "Star of Sierra Leone"have not been graded for color and clarity, in all probability they are D-color diamonds and perhaps internally flawless.
