The 7.42-carat green emerald from Zambia, assessed by Lotus Gemology and noted as a rare minor oil-enhanced stone, represents a fascinating specimen within the world of precious gemstones. Emeralds are a variety of the mineral beryl colored by trace amounts of chromium and vanadium, renowned for their intense green hues ranging from light to deep shades. Zambian emeralds are known for clarity and a slightly bluish-green tone, distinct from Colombian counterparts. The mention of minor oil treatment refers to a common practice where oils or resins are applied to enhance clarity by filling surface-reaching fissures. This treatment is widely accepted in the gem trade. Such high-carat emeralds are prized for their use in fine jewelry and as investment pieces, reflecting beauty, rarity, and natural geological history.
