Amber (fossilized plant resin; commonly succinite, C10H16O)

AI-generated identification · may be incorrect

Mohs hardness 2–2.5; translucent honey-orange to brown with resinous/waxy luster, conchoidal fracture, and no cleavage. Very low density (about 1.05–1.10) and may fluoresce blue-white under UV.

Physical properties

Mohs hardness 2–2.5; translucent honey-orange to brown with resinous/waxy luster, conchoidal fracture, and no cleavage. Very low density (about 1.05–1.10) and may fluoresce blue-white under UV.

Formation & geological history

Fossilized tree resin polymerized and oxidized over roughly 20–50 million years, commonly in Paleogene coastal or deltaic sediments. The specimen appears naturally rough and partly translucent, with internal flow textures and inclusions.

Uses & applications

Cut and polished for jewelry, ornaments, and collecting; historically used for incense, varnish, and decorative carving. Natural, transparent pieces can be valuable, especially with insects or other inclusions.

Geological facts

Amber is organic rather than a true mineral because it lacks a crystalline structure. It becomes electrostatically charged when rubbed and may soften or emit a pine-like odor when gently warmed.

Field identification & locations

Likely Baltic-region amber based on color and appearance, though origin cannot be confirmed visually; major sources include the Baltic coast, Dominican Republic, Mexico, Myanmar, and Indonesia. Confirm with density, UV fluorescence, static charge, and careful examination for natural resin flow; avoid destructive tests.
