Amber (Burmite)

Physical Properties

Hardness: 2.5–3 on Mohs scale; Color: Swirling deep reds, browns, and blacks with unique 'root' patterns; Luster: Resinous to vitreous; Crystal structure: Amorphous; Specific gravity: 1.05–1.10.

Formation & Geological History

Formed from the fossilized resin of ancient coniferous trees (Metasequoia or Araucaria). Specifically, Burmite is from the Cretaceous period (approx. 99 million years ago), found in the Hukawng Valley of Myanmar.

Uses & Applications

Predominantly used for jewelry (beads, pendants), lapidary arts, and scientific study (fossil inclusions).

Geological Facts

Burmese amber is one of the hardest types of amber. The 'Root Amber' variety shown here contains significant amounts of calcite and other minerals that create the opaque, swirly, stone-like patterns resembling marble or wood grain.

Field Identification & Locations

Identify by its light weight, warm feel to the touch, and distinct pine smell when rubbed or pierced with a hot needle. It floats in saturated salt water but sinks in fresh water.
