Polished amber
Amber (fossilized plant resin), commonly succinite; organic mineraloid rather than a true mineral

Physical properties
Honey-brown, translucent, resinous luster with irregular fractures and possible inclusions; Mohs hardness about 2–2.5, very low density (about 1.05–1.10), and no crystal structure or cleavage. The specimen appears carved or naturally shaped into a small animal-like form and may be polished or coated.
Formation & geological history
Amber formed from fossilized tree resin, commonly during the Cretaceous–Paleogene and younger periods, with Baltic amber largely about 34–48 million years old. It is recovered from lignite-bearing sediments and coastal deposits.
Uses & applications
Used for beads, carvings, ornaments, and jewelry; historically valued for fragrance, decoration, and folklore. Small common pieces generally have modest market value.
Geological facts
Amber often becomes electrostatically charged when rubbed (“electron” derives from Greek ēlektron, amber). Inclusions such as insects, plant fragments, and air bubbles can greatly increase value.
Field identification & locations
Identify it by its warm lightweight feel, resinous appearance, ability to float in concentrated salt water, and softening or pine-like odor when carefully warmed; avoid destructive tests. Common sources include the Baltic region, Dominican Republic, Myanmar, Mexico, and Indonesia.
