Rough Emerald Gemstones

This parcel consists of a significant quantity of rough, uncut emerald gemstones, a variety of the mineral beryl. The stones exhibit a range of vibrant green hues, from deep forest green to lighter, slightly yellowish-green tones, which are characteristic of chromium and vanadium trace elements. The individual crystals vary in size, generally appearing to be between 5mm to 15mm in length. Their physical structure displays typical hexagonal crystal habits, though many pieces are fragmentary or water-worn with irregular, sub-conchoidal fractures. The surface of the stones varies from semi-translucent to opaque, with a noticeable presence of internal inclusions, including 'jardin' (fractures and liquid inclusions) and potential black matrix remnants or carbon spots. The luster is vitreous on fractured surfaces. There is no evidence of professional cut or polish, indicating these are mine-run specimens or sorted rough intended for lapidary work. The overall condition reflects natural raw material, with presence of surface-reaching fissures common to the species. The saturated color indicates potential origins from renowned deposits such as Colombia, Zambia, or Brazil, though gemological testing would be required for confirmation. The parcel shows varying degrees of transparency, with some pieces appearing to have 'facet-grade' potential while others are more suitable for cabochons or carving.
