Rainbow Calsilica Fancy Cab
Gorgeous Rainbow Calsilica fancy cab.
Lovely blues, greens and greys in bands.
There is a dispute about the origin of this gem, but I would say it is most likely to be a composite of natural calcium silicate material and then dyed - gorgeous.
Flat backed and polished front and back.
11.6 x 26.1 x 4.5 mm approx.
