This ring was handcrafted by a good friend, Jim Taylor. In creating this ring he combined an Arizona chrysocolla cabochon and a turquoise cabochon with sterling silver . Actually, Jim also polished the free-form cabochons. The smaller cab is turquoise and is about 3/8" by 7/16". The larger free-form chrysocolla cab is about 3/4" by 7/16" and has a quartz and possibly a little gem silica. The ring is 1 5/8" by 7/8".
