Coloured diamonds

Rarity equals value when it comes to diamonds. Normally the absence of colour in a diamond will increase its value, but certain colours have proven to be very rare and therefore very valuable, specifically pink, blue and green diamonds. Letšeng has produced some magnificent coloured diamonds, specifically pink and blue, which have achieved the top 10 highest US$ per carat of all Letšeng diamonds sold to date. Letšeng has also produced yellow diamonds which, although not as valuable as white diamonds, have been polished into extraordinary pieces.
