Green chalcedony (possibly jade or serpentine)

Microcrystalline quartz, SiO₂; exact identification is uncertain from the image

AI-generated identification · may be incorrect

Small, pale green, translucent-to-opaque fragment with a waxy/glassy luster and irregular fracture. Chalcedony has Mohs hardness 6.5–7 and a trigonal quartz structure; jade and serpentine lookalikes require testing to distinguish.

Physical properties

Formation & geological history

If chalcedony, silica-rich fluids deposited quartz in rock cavities or fractures; its geological age depends on the host deposit. The specimen appears naturally formed, but its source cannot be determined visually.

Uses & applications

Green chalcedony is used for carvings, beads, and jewelry; similar-looking jade may be valued more highly, while serpentine is commonly ornamental.

Geological facts

Green color can result from trace elements or inclusions. Visual appearance alone cannot reliably separate chalcedony from jade or serpentine.

Field identification & locations

Check hardness, density, and internal texture; a gemological or laboratory test is needed for confident identification. Green chalcedony occurs worldwide, including Brazil, India, and Madagascar.
