What is it traditionally used for?

What does a crystal grade (A, AA, or AAA) actually mean?

Crystal grades reflect visual quality within a single batch. Grade A is standard quality with typical inclusions. Grade AA shows stronger color saturation, cleaner surface, and tighter sizing. Grade AAA represents the top 10 to 15 percent of any batch: exceptional clarity, consistent color, and minimal surface variation. At Beyond Bohemian, grades are assessed by Paul Oliver at point of purchase.

Will I receive the exact piece shown, or one chosen from your stock?

For bulk listings sold by weight or piece count, you receive pieces from the same batch shown in the photos. Each piece is hand-selected at the time of packing. For unique specimens listed individually, you receive the exact piece photographed. The listing will specify which applies.

Black obsidian is volcanic glass. Sharp, glossy, formed when lava cooled too fast to crystallize. It's one of the oldest materials humans have used for tools, and it still feels ancient when you hold a piece. Named after Obsius, a Roman who reportedly first found it in Ethiopia.

These tumbled stones come from Salta Province, Argentina.

Black obsidian is traditionally a stone for a sense of groundedness when things feel uncertain, staying connected to your body and the moment, and cleansing. It's traditionally linked to the root chakra. If that resonates, keep a piece in your pocket during the day for a steadying presence. Let it become part of your own quiet routine.

These are traditional associations drawn from historical practice. This stone is not a substitute for medical or mental health care.
