“Quartz – Herkimer Diamond. Vasco Trancoso collection. Size: 5,25 x 4 x 3 cm This one is special...more than most of it is a single 5.25 cm crystal ON MATRIX (rare) and NOT REPAIRED. This piece was from the Bill Metropolis collection, is really a "jewel" and stands out. The crystal is transparent and you can look through to the matrix inside. Photo courtesy from The Arkenstone. ”
