Polished crescent-shaped stone pendant

Likely black jade, basalt, or other dark silicate stone; exact identification requires testing

AI-generated identification · may be incorrect

Dark gray-black, finely granular and polished, with subdued vitreous-to-waxy luster; likely Mohs 6–7, opaque, and lacking visible cleavage. The mottled surface may reflect mineral grains or alteration.

Physical properties

Formation & geological history

If basalt, it formed from cooled volcanic lava; if jade, it formed through metamorphism and consists mainly of jadeite or nephrite. Geological age and locality cannot be determined from the photograph.

Uses & applications

Likely used as jewelry or a talisman; comparable polished stone pendants are commonly inexpensive decorative items.

Geological facts

The crescent shape is human-cut and polished, so shape alone does not identify the material. A streak, specific-gravity, hardness, and refractive-index test would distinguish likely candidates.

Field identification & locations

Common possibilities include basalt, slate, serpentine, nephrite, or black jade. Check for natural grain, test hardness against glass, inspect the streak, and avoid destructive testing if it is a valued pendant.
