gemstone

Raw amber

Fossilized plant resin; predominantly polymerized diterpenoid resin (succinite when Baltic-type)

AI-generated identification · may be incorrect

Typically Mohs hardness 2–2.5, very light specific gravity (~1.05–1.10), resinous to vitreous luster, and transparent to opaque yellow, orange, red-brown, or brown color. It is amorphous rather than crystalline, often warm to the touch and may contain inclusions.

Physical properties

Formation & geological history

Amber forms when ancient tree resin polymerizes and matures during burial, commonly over tens of millions of years; Baltic amber is chiefly Eocene (~44–34 million years old). The specimen’s orange-brown, rough appearance is consistent with amber but cannot establish locality from the image alone.

Uses & applications

Used for beads, cabochons, carvings, ornaments, and collecting; historically used as incense and folk medicine. It has limited industrial use.

Geological facts

Amber can float in concentrated salt water and may produce a pine-like odor when gently warmed; rubbing can create static electricity. The visible pale vein may be a fracture, weathering rind, or internal resin feature.

Field identification & locations

Common sources include Baltic shores, the Dominican Republic, Mexico, Myanmar, and Indonesia. Check with a loupe, UV light, saltwater flotation, and careful thermal testing; avoid destructive tests because copal, plastic, and pressed amber can resemble it.
