Opal is a fairly simple molecule. A hydrated silicon dioxide, opal's chemical formula is SiO2.nH2O. The n means that any number of water molecules can be associated with each SiO2 molecule. More accurately, the number of waters varies, is unknown, or both. In other words, n means we don't know.
This rough have cracks that are not shown in the pictures and make it worthless. Very disappointed with it, as neither description, neither photos lead to think that is so heavy cracked and is pure waste of money.
