Obsidian, being a very resistant volcanic stone, purifies easily. Fumigation with Palo Santo or sage is the gentlest method. A quick rinse under lukewarm running water is also possible, making sure to dry it immediately to protect the jewelry's metal. To recharge it deeply, you can place your Obsidian in the earth for a few hours or expose it to the gentle light of the full moon. You can also place it on a rock crystal cluster or an amethyst geode to amplify its grounding and protective energy.
