Type III Coloured gemstone
Emeralds typically contain inclusions that are visible to the unaided eye. Because of this, trade members and some consumers understand and accept the presence of inclusions in emeralds. Eye-clean emeralds are especially valuable because they’re so rare. Emerald inclusions are often described as looking mossy or garden-like. They’re sometimes called “jardin,” which is French for garden.
