Condition Notes: This 10.96 carat emerald originates from the famed Sandawana mines in Zimbabwe’s Mweza Greenstone Belt, a region known for producing some of the world’s most vivid emeralds. Discovered in the late 1920s and commercially mined by the 1950s, Sandawana gained a reputation for high-quality emeralds, particularly melee. Most stones from this locality are small, making this gem exceptionally rare and desirable among collectors. The mine’s remote location and artisanal mining practices have always limited production, with current activity remaining sporadic. Inclusions are moderate to the naked eye and consistent with F1 clarity enhancement. Minor cavities are present from surface reaching inclusions confined to the microscopic level.
