About jet
Jet is an organic gemstone formed from fossilized, coalified wood under high pressure, usually from Jurassic-age deposits. It is opaque and typically deep black, with a lightweight feel and warm touch compared to inorganic stones. With Mohs hardness around 2.5–4, it is relatively soft and can be carved or turned easily, though it is susceptible to scratching and breakage if mishandled.
