I have no idea what this VERY colorful material is! I cut the rough myself; the exterior resembled Lace Agate, but once I started cutting into it, all resemblance to Lace Agate disappeared. Too pretty, so I'm keeping it for the collection. Sorry!

Dimensions: 45mm x 33mm x 8mm.  Weight: 88.15 carats.

This cabochon is in my personal collection; it is not available for sale.
