Looking for some beautiful black onyx for your collection or craft projects? This Zentron Crystals pack delivers one full pound of tumbled black onyx stones. They're mined in Brazil and have that classic, sleek black color with a smooth, polished finish from tumbling. The stones are all unique – sizes and shapes will vary slightly within the pound, which is part of the natural charm. They're perfect for a variety of uses: crystal healing, reiki, chakra work, meditation, or simply as decorative pieces in a bowl or vase. If you're into lapidary arts, you can use them for further tumbling, cutting, or cabbing. The pack comes with a handy 5x7 inch carrying pouch and an information sheet about onyx from Zentron Crystals. Whether you're a crystal enthusiast, a jewelry maker, or just love the grounding energy of black stones, this is a great value bundle to get a good amount of quality onyx.
