Physical properties
Hardness: 2.0-2.5 on Mohs scale; Color: Honey yellow to dark brown; Luster: Resinous; Crystal structure: Amorphous (non-crystalline); Cleavage: None; Specific Gravity: 1.05-1.10 (floats in saltwater).
Formation & geological history
Formed from the fossilization of resin from extinct coniferous trees (primarily Pinus succinifera) during the Eocene to Miocene epochs (approx. 30-50 million years ago); found in sedimentary deposits like marine sands or clays.
Uses & applications
Predominantly used in jewelry (beads, cabochons), carvings, and perfume industry (amber oil). Highly valued by scientists for paleontological research when containing inclusions.
Geological facts
Amber is organic, not a mineral. It can preserve ancient biological matter, such as insects and plant parts, in near-perfect 3D detail. It is one of the few 'gemstones' that feels warm to the touch and can generate static electricity when rubbed.
Field identification & locations
Identify by its light weight (low density) and the 'saltwater test' (it floats in saturated saltwater). Often found along the shores of the Baltic Sea or in mines in the Dominican Republic. Collectors look for clarity and biological inclusions.
