One Cabochon. 40x30mm stone teardrop, pear

Deep Blue Lapis Lazuli.  Not marked but looks mainly a nice B grade.   Teardrop, pear shape in 40x30mm.

Dark shades of violet denim blue, gold flecks and possibly some white swirls.   (This  is a representative picture, each stone will have natural variances.) Great to bead around, make into a brooch.
