Opals are structurally composed of tiny spheres of silica

which has been exposed to heat after mining in order to enhance color (heat-treated Amethyst)

They were first found in New York in shale and mudstone during the construction of the Erie Canal

those encounters would have been a toss up in regard to the outcome of a battle

The pressure of the sediment eventually causes the sediment around the void to turn into rock

It can occur in any color depending on the mineral content of the original sediment. Beautiful patterns can also occur in jasper. This happens when the original rock forming materials are fractured or distorted in the ground and then are later filled in with other minerals. A specific jasper may be named for its location or may be named imaginatively by describing its
