This is a spectacular occurrence. A calcite crystal has miraculously attached itself to a super clear Herkimer Diamond. It is all natural, not reconstructed or repaired. For anyone (like me) who knows Herkimer Diamonds this basically never happens. Under the calcite, and within the Quartz, is a thin layer of Anthraxolite (carbon) included. The crystals are in great, pristine condition. You may never see another like it.
