Two of the stones I've seen at the Senckenberg Museum . One of them is amethyst, do you know what's the other one?
Amethyst is a violet variety of quartz. The name comes from the ancient Greek "amethystos", which means "not drunken", a reference to the belief that the stone protected its owner from drunkenness.
The ancient Greeks wore amethyst and made drinking vessels decorated with it in the belief that it would prevent intoxication. It is one of several forms of quartz. Amethyst is a semiprecious stone.

ReplyDeleteMy dad had a white marble mine from which he made his bear sculptures , and further moulded them into his aluminum pieces. I should pay more attention to " rocks "....smiling...
ReplyDeleteI'd love to see these in person! I can't imagine what the multi coloured one is. I had the great joy of seeing massive amethyst rock walls and samples in northern Ontario where they mind amethyst. Many mines have tourist attrractions, you are allowed to pick over the tailings and pay by weight for any crystals you find. They also have their own sales, all manner of crystals from little gems to great encrusted rocks, priced by quality and weight. The prices are cheap compared to what you see when a sample gets to the store. The Terry Fox Monument is perched on a dias of amethyst rock walls. It's quite stunning.

ReplyDeleteFluorite came to mind for the first one, but not really sure
ReplyDeleteKinda looks like tourmaline or liddacoatite. Neat-looking, in any case. Some bicolor stones are created artificially through irradiation, like ametrine, but there are some neat natural bi- or tri-color stones as well.
