Quite suddenly and recently, I'm seeing this stone everywhere online. It's green (and white/cream) but it's definitely not opal and I seriously doubt it's Swiss. It comes in several distinct patterns, as this Google Image Search illustrates: http://goo.gl/8HH8JpCan anyone tell me this stone's composition and/or scientific name? Thanks. |

Looks like another one of those terrible marketing names that only add confusion.
No NOT Opal.
Appears to be maybe a serpentine or Epidote type rock, Seems to vary some in the samples shown. Tough to work from pictures only.

Got something that looks a heck of a lot like our mystery stone.
Click over to T Rocks Quartzite site and look at the photo of their Brazilian Chrysotile. It's in the rough stone section. Maybe we ought to let the Chinese cut this one if the name is accurate it is a form of asbestos.
Just do a search on Brazilian Chrysotile.

one site says
"Swiss opal is dark green in color with light patches of chicken wire or lizard skin like pattern on it. When exposed to light, it emanates spectacular color flashes that change along with the angle from which it is viewed.
Along with the basic body color, these stones show a rare flashing of rainbow colors which is otherwise known as opalescence. However the intensity & impact of these color flashes are less than that of precious opals."

Didn't find any videos of it. I wanted to see the color flash.

I have a couple of slabs from about 5 years back. Forget what it was called back then. I do seem to remember it was from South America and Brazil sounds right. Some of the posted pics do look like a Chrysotile type stone but i would say what i have is more like a Serpentine. Definitely not opal.

Probable play of light off compressed chrysotile fibers some what similar to what tiger eye does which is a form of quartz that has replaced crocidolite .
Hope some one has not compared this to opals play of light from diffracted light.

Chrysotile is the fibrous variety of Serpentine. Any rough serpentine will have at least a small amount of chrysotile in it. Always work serpentine wet and best with a respirator with P100 filters to prevent any more asbestos exposure. I have worked as an asbestos regulator for the last 25 years and any exposure just increases you lifetime risk of cancer.
