Once in awhile at the bottom of pockets in Herkimer, there will be a sand that includes perfect tiny micro herkimer diamonds. Over many years I've picked out these herkimers from the sand and graded out the perfectly clear, complete crystals. The pendant is a hand-blown pyrex bottle topped with a sterling silver cap. I added a cherry red gem spinel crystal from Burma, to add contrast both in form and color. Each one is completely unique as these are labor intensive, original creations. The pic is a consisitent representative of what we currently have in stock.
