Needles blue agate slab




A few Needles blue agate slabs are available. This rare stone has small streaks of the blue agate which had been assayed and was found to have a large number of minerals in the  Needles blue agate material.  The blue green areas of gem silica is in a rhyolite porphyry. The location where the Needles blue agate was found is the only known one in the USA. The Needles Gem Club and their guests were the only ones who could collect the material.  We hope to  get more slabs made at some point. SKU: 539s
