Natural "bubbles" were isolated then shaped and polished to form this 1 1/4th inches tall cabechon.  The turquoise blues and purples come from vapor deposition of titanium under a vacuum in high heat.  Sterling silver was hand textured and soldered to hold the stone.  The pendant is about 1 1/2 inches tall.  The sterling silver 18 inch chain attaches via oblong lobster clasp.
