Tumbled emerald chips

Emerald, green beryl (Be₃Al₂Si₆O₁₈), colored mainly by chromium and/or vanadium

AI-generated identification · may be incorrect

Typically Mohs hardness 7.5–8, green color, vitreous luster, hexagonal crystal structure, and poor basal cleavage; these pieces are polished/tumbled, obscuring natural crystal faces. The appearance may also represent lower-grade green beryl or dyed material, which cannot be confirmed visually.

AI Estimated Value

About $5–$30 for a small lot of common tumbled chips; roughly $50–$500+ if verified natural emerald content is attractive, with gem-quality stones valued far higher.

Physical properties

Formation & geological history

Emerald forms in hydrothermal veins and metamorphic rocks where beryllium-rich fluids interact with chromium- or vanadium-bearing rocks; deposits range from Precambrian to younger ages. Major sources include Colombia, Zambia, Brazil, Zimbabwe, and Afghanistan.

Uses & applications

Used primarily for jewelry when transparent and clean; opaque or heavily included chips are sold for crafts, decorative inlays, specimens, and metaphysical collections.

Geological facts

Natural emerald commonly contains three-phase fluid inclusions, called “jardin,” and is frequently fracture-filled or oiled to improve apparent clarity. Most pieces shown are low-grade chips rather than facet-quality gems.

Field identification & locations

Identify genuine emerald by saturated green color, glassy luster, hardness, and diagnostic inclusions; definitive identification requires refractive-index, specific-gravity, and laboratory testing. Common commercial chip strands often contain mixed green beryl or dyed quartz.
