Swiss Opal Diamond Shaped Cab
Swiss Opal diamond shaped cab.
This is the name this gem is commercial known as, due to the shimmering quality of the stone, although it isn't actually opal at all. The silvery bands are formed from Chrysotile, which is the fibrous variety of Serpentine.
Lovely silvery green bands in a matrix of shaded green stone. Some translucency to the darker green areas.
Flat backed and polished on the face only.
42.2 x 22 x 5 mm approx.
