Amber is actually a geological era in plant resins through petrochemical product, is 40 million years ago fossil pine resin, is an entity preserved fossils. Its main ingredient is carbon, hydrogen, oxygen and small amounts of sulfur, hardness 2-3, specific gravity 1.05-1.1, melting point 150c-180c, light 250c-375c. Amber, pearls and coral for the three organic gemstones.
Amber is amorphous, irregular lumps, the size of the fine particles to large chunks of weight a few pounds. Raw material resin gloss, gloss resin was polished to near the glass luster. Hardness is only 2-2.5. Can be easily cut with a knife, poor toughness, crack was conchoidal.
The proportion of transparent amber about 1.05 to 1.09, with a large number of bubbles turbid amber（ tiffany wholesale ）, low specific gravity 1.0. Amber's slight change in refractive index, but usually close to 1.54, as low as 1.539 to as high as 1.545. Because Amber is a amorphous material, it is isotropic, no cleavage, no pleochroism, and unparalleled refraction. According to a lack of toughness, a powder inclusions, oil sheen, glass fracture, and not the ability of highly polished, can identify it belongs to the fat-like amber. Amber often has inclusions, such as insects, seeds and other foreign objects are captured before the resin hardened. Germans burned amber as stone, because it is at very low temperature combustion.
