Luna Agate or Ocean Jasper, I'm still not sure! But this freeform cabochon sure is a looker! It has light gray & purple patterns that are translucent in places. There is a chip on the left edge, actually an orb that fell out; it's toward the bottom of the gray lacy part on the left and is not visible from the front of the cab. Gloria made me keep this one...

Dimensions: 42mm x 26mm x 7mm.  Weight: 57.35 carats.

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