The Emerald Only Mix contains 2 gallons of crushed local rough mine ore with Emeralds from various world-wide locations mixed in. The mine ore is mostly white colored Pegmatite rock mostly containing Feldspar, Quartz, and Mica. The Emeralds are found scattered throughout the white ore and very few gems other than Emeralds will be found. If you want a variety of gemstones (including Emeralds) we recommend our other mixes in the store. The second photo shows an average find of Emeralds once sorted out of the white rock. This bucket weighs approximately 30 pounds and is shipped in a bag in a box by USPS Priority Mail for 2 to 3 day delivery to most US addresses. We include a full-color gem identification chart in the box and a bonus piece of Mica.
