Rainbow Calsilica Marquise Cabs
Rainbow Calsilica marquise cabs.
Lovely blues, greens, reds 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 polished on the faces.
Great earring stones.
26.6 x 8.7 x 3.5 mm approx.
