Emerald is one of four precious stones along with diamond, ruby and sapphire. Its green colour varies enormously from one stone to another.

The history of the emerald dates back 2.97 billion years in South Africa, where the oldest emeralds were found. It is even said that Cleopatra was a fan of these beautiful green rocks. During her reign, she took control of the emerald mines near the Red Sea and was able to adorn her jewellery with as many emeralds as her heart desired.

Emeralds are particularly rare gemstones because their formation requires exceptional geological conditions.

They are therefore among the most expensive stones on the secondary market, especially those from Colombia, which are particularly the purest.
