The 18K Blue Moon Amulet adds the magic of Blue Moonstone to our classic rock crystal amulet. North, south, east and west are each represented by a cabochon-cut Blue Moonstone. A single tanzanite at the base brings an otherworldly glow to the already luminous natural rock crystal. #M# 18K gold+ Natural Rock Crystal+ Blue Moonstone, oval cabochon cut, 2.20ct+ Tanzanite 0.25ct+ Length: 51mm/2.0"; Width: 21mm/0.85"+ Imported+ #L# 18K gold+ Natural Rock Crystal+ Blue Moonstone, oval cabochon cut, 3.72ct+ Tanzanite 0.25ct+ Length: 60mm/2.4"; Width: 29mm/1.2"+ Imported+
