1 pcs Green Emerald - 11.77 ct - Gemological Science International (GSI) - Zambian Emerald

Emerald, a precious variety of the mineral beryl, is renowned for its lush green color deriving from trace amounts of chromium and vanadium. This particular stone is an 11.77-carat emerald originating from Zambia, as confirmed by Gemological Science International (GSI). Zambian emeralds are highly regarded for their deep green hues with less included clouds compared to other sources, often offering superior transparency and brilliance. Emeralds have a Mohs hardness of about 7.5 to 8 but typically contain inclusions known as 'jardin,' which are accepted as part of their natural beauty. Zambian stones are valued in both fine jewelry and collector markets due to their color intensity and clarity. Certification from GSI assures buyers of the gemstone's authenticity and origin.
