Identification

Name: Amber

Scientific classification: Organic Gem Material (Fossil Resin)

Hardness: 2.25 Mohs

Transparency: translucent

Lustre: resinous

Crystal system: Amorphous

Primary colour: Honey

Secondary colour: Orange

Colour family: Oranges & Yellows

Low SG, resinous lustre, UV fluorescence, and warm feel help separate amber from many imitations.

Verification Status

Status: verified-core-fields

Reference priority: GIA, Gem-A, Mindat, International Gem Society

Core identity, locality, and physical-property fields reviewed against standard gemological references.

Values are reported as practical gemological ranges where appropriate.

Geological environment: Sedimentary deposits containing fossil resin-bearing horizons

Principal mining regions: Baltic region (Poland, Lithuania, Russia), Dominican Republic, Mexico, Myanmar

Important commercial sources: The Baltic region is the dominant commercial source, with additional important material from Dominican and Mexican deposits

Historical significance: Major historical trade material and source of archaeological inclusions.

Common treatments: Heat clarification, pressing/reconstruction, and dyeing are common.

Synthetic or imitation forms: Copal, pressed amber, plastic, and glass are common imitations.

Common look-alikes: Copal, celluloid/plastic, glass

Jewellery uses: Used in beads, carvings, cabochons, and collector inclusions.

Care recommendations: Very soft and heat-sensitive; avoid solvents, perfumes, high heat, and ultrasonic cleaning.
