Emerald : a stone with the colour of hope
Emeralds are one of the most sought after gemstones due to their scarcity, beauty and characteristic green colour.
They belong to the beryl family. The finest specimens generally come from Columbia and from the Muzo mine more specifically. Other mines located in Brazil or the Russian Urals also produce fine quality stones. They frequently contain natural “mossy” inclusions that do not affect their clarity if they are low in number. This gem is highly-prized by jewellers.
