Physical properties
Hardness: 2.0-2.5 on Mohs scale; Color: Honey-yellow to orange-brown; Luster: Resinous; Crystal structure: Amorphous (non-crystalline); Cleavage: None (conchoidal fracture); Specific gravity: 1.05-1.10 (very light, floats in salt water).
Formation & geological history
Formed through the polymerization and fossilization of tree resin from ancient coniferous or deciduous trees. This specimen likely dates from the Eocene or Miocene epochs (approx. 20-50 million years ago).
Uses & applications
Commonly used in jewelry, as decorative carvings, in high-end perfume production (historical), and of immense value to the scientific community when containing fossilized inclusions (entombed insects or plants).
Geological facts
Amber is not a true mineral because it is organic and lacks a crystal structure. It is famous for preserving delicate soft-bodied organisms that otherwise would not fossilize. It can be scientifically tested by its static charge or by floating in a saturated salt solution.
Field identification & locations
Identify in the field by its light weight (it feels 'warm' compared to cold quartz) and its resinous luster. It is commonly found in Baltic Sea regions, the Dominican Republic, and Myanmar. It can be distinguished from plastic by the 'hot needle test' (smells like pine) and by its ability to float in salt water.
