Jet is a product of decomposition of wood from 180 million years ago, most often wood from the Araucariaceae family.
Jet is brown coal, the lowest rank coal, but it is a precious stone.
Unlike onyx, it is warm to the touch.
It can be easily polished to a glossy surface. It is derived from wood that has been transformed under extreme pressure in a moist, oxygen-free environment.
Even the cellular structure of wood can be detected under high magnification.
It electrifies like amber.
It smells of paraffin when heated (so you can identify a fake).
Latin name: gagates.
Each of our products can have amber and jet stones.
