Large Amethyst

By admin  

The house we purchased has several large rocks in the yard.?

Someone mentioned that one of them might be Amethyst. It is a large rock about 2ft x 3ft. Is there any way I can tell without breaking it. If it is, does it have any value? I have one that I think is called brain coral. Any info on this one? Thanks for your help..:)

Amethyst is purple or violet crystals, and has a hardness of 7 on the Moh's scale, meaning it will scratch glass with about the same effort as other quartz minerals (Hint: most sand is made up of quartz minerals). Being a form of quartz, few acids react with it, so if you put it in a cup of warm vinegar (that's weak acetic acid) it shouldn't have a steady stream of tiny bubbles like limestone or calcite would have. When you heat Amethyst it usually turns permanently yellow.

Amethyst used to be as valuable as emeralds, rubies, diamonds, and other precious gemstones, that is until discoveries of huge deposits of it in Brazil made the value drop a great deal, but it is still worth a fair amount to collectors if it is an unusual specimen.
