Dino bones are fossilized by an interesting process where the bone rots through and minerals fill the cavity where the bones were. Essentially a dinosaur fossil isn't made of what the dinosaur was born with.
Jet is one of the end products of how fossil fuels are formed. Whereby organic materials like plants, animals and bacteria and what have you get subjected to heat and pressure for several eons.
Afterwards what you get is based on how much heat, pressure or combination was applied.
Largely, when non-organic minerals are subjected to this kind of heat and pressure, you get all sorts of other minerals such as amethyst or Ruby or what have you.
Jet, Amber, and Pearl are all things that used to be alive. Largely, the others never were and started as minerals and elements and such and worked their way to be eventually be other mineral compounds.
To put it simply:. Some gemstones used to be made of breathing stuff. Others were not.
