Possibly dyed Ca₂B₅SiO₉(OH)₅ (howlite) or MgCO₃ (magnesite); identification is uncertain from the photo

AI-generated identification · may be incorrect

Small, rounded and highly polished, with a mottled green-and-dark pattern. Hardness and crystal structure cannot be determined visually; the uniform vivid color is common in dyed beads.

Physical properties

Small, rounded and highly polished, with a mottled green-and-dark pattern. Hardness and crystal structure cannot be determined visually; the uniform vivid color is common in dyed beads.

Formation & geological history

Howlite and magnesite form in mineral-rich deposits, often in evaporitic or hydrothermal settings. The bead has been shaped, polished, and likely dyed; its geological age and source are unknown.

Uses & applications

Used mainly for inexpensive jewelry and craft beads.

Geological facts

Dyed howlite is often sold as imitation turquoise, though the bead’s appearance alone cannot confirm its material.

Field identification & locations

A close-up or tests would be needed to distinguish dyed howlite, magnesite, and other green stones. The reported Rajasthan-area location does not establish the bead’s geological origin because it may be manufactured or imported.
