Physical properties
Hardness: 2.0-2.5 on Mohs scale; Color: Honey-yellow, orange, or deep reddish-brown (as seen in image); Luster: Resinous; Crystal structure: Amorphous; Fracture: Conchoidal; Specific Gravity: 1.05-1.10 (very buoyant).
Formation & geological history
Formed through the polymerization and fossilization of tree resin from extinct coniferous trees. This sample appears consistent with Eocene or Miocene aged deposits. It requires anaerobic conditions to fossilize rather than decay.
Uses & applications
Primarily used in jewelry, decorative arts, and perfumery. It is of high scientific value when containing prehistoric inclusions like insects or plant matter.
Geological facts
Amber is not a true mineral because it is organic and lacks a crystalline structure. It is famous for preserving delicate soft-tissue organisms (inclusions) for millions of years. It produces static electricity when rubbed with a cloth.
Field identification & locations
Identify in the field by its light weight, warm feel to the touch (unlike stone), and ability to float in saturated salt water. Common locations include the Baltic Sea region, Dominican Republic, and Myanmar.
