108 carat Pink Diamond Discovered in Lesotho

A fancy intense pink rough diamond weighing 108.39 carats has been recovered in the Kingdom of Lesotho, at the Kao mine operated by Storm Mountain Diamonds. This rare Type IIa gemstone is one of the largest pink diamonds in history to have been recovered.

Unlike other fancy colors, the unique coloration of pink diamonds is caused by distortions in the crystal lattice resulting from intense heat and pressure during their formation. Fewer than 2% of natural diamonds fall into the highly pure Type IIa classification, contributing to this crystal’s exceptional rarity. According to Lesotho Minister of Natural Resources Mohlomi Moleko:

This is one of the most significant diamonds found to date in Lesotho.

The mining team in Lesotho have submitted a list of names for this new 108 carat specimen. More to come.
