Polished amber-like organic gemstone

Amber (fossilized tree resin), commonly succinite; exact identification is uncertain from the image

AI-generated identification · may be incorrect

Honey-brown to dark brown, translucent with black inclusions and resinous luster; Mohs hardness about 2–2.5, amorphous rather than crystalline, with no cleavage and specific gravity about 1.05–1.10. The rounded, glossy surface indicates polishing.

Physical properties

Honey-brown to dark brown, translucent with black inclusions and resinous luster; Mohs hardness about 2–2.5, amorphous rather than crystalline, with no cleavage and specific gravity about 1.05–1.10. The rounded, glossy surface indicates polishing.

Formation & geological history

Amber formed when ancient conifer or flowering-plant resin polymerized and fossilized in sediments, commonly over roughly 2–100 million years. Major deposits occur in Baltic-region Paleogene sediments, the Dominican Republic, Myanmar, Mexico, and Indonesia.

Uses & applications

Used for cabochon jewelry, carvings, beads, ornaments, and scientific inclusions; it is lightweight and warm to the touch. Black patches may be organic debris, weathering, or plant material rather than a separate mineral.

Geological facts

Amber floats in saturated salt water and typically becomes electrostatically charged when rubbed. Genuine amber may fluoresce blue-white or yellow under long-wave UV and softens or smells resinous when heated, though destructive tests are best avoided.

Field identification & locations

Identify by very low weight, resinous feel, warm touch, static charge, and possible insect or plant inclusions; copal and plastic imitations are common. The image alone cannot exclude copal or dyed resin.
