This is a one-of-kind necklace handmade in California: Natural Obsidian stones are beaded on your new crystal healing necklace. Rainbow Obsidian is the most sought after form of Obsidian because of its brilliant sheen. Like all Obsidian, this healing crystal forms when volcanic lava cools quickly. Microscopic crystals and bubbles of Mica get trapped in this particular form of Obsidian to reveal subtle sheen and muted rainbow colors moving on the stone. The natural stones are strung with a fan of matte gold and brass metal blades on a necklace secured with a toggle clasp. You will receive the exact necklace as pictured in a Kraft gift box from I Dig Crystals. Crystal Healing Properties: Rainbow Obsidian is our favorite crystal to counteract negative energies and transmute them to positive, thus protecting our aura from being drained. Use Rainbow Obsidian to ground the Root Chakra. It brings joy and happiness. It unhooks unhealthy relationships from your heart.Measures: approximately 16 inches (longest metal fan: 2 inches)Chakra Balancing: Root Chakras Thank you for your positive presence at I Dig Crystals
