Every piece begins as natural Black Obsidian — each batch documented and recorded against your SKU.

No two pieces are alike — each stone carries its own color, clarity, and quiet imperfections.

Every batch is tied to a purchase record, a ZENDIAC SKU, a Batch ID, and supplier documentation.

Cutting and polishing a stone is craft. Replacing it with something else is not. Here is where we draw the line.

Cutting, shaping, drilling, polishing, and cleaning are how raw material becomes something you can wear.

When a stone is disclosed as natural, it is natural stone — not laboratory-created, reconstructed, composite, or imitation material.

Dyeing, coating, filling, impregnation, stabilization, irradiation, or heat treatment must be declared to us and reviewed before we accept a batch.

We sample every batch before it ships. How much we sample depends on volume, material risk, and the supplier's history.

Verification-First Material Review

Natural variation alone is not a defect.

If you raise a documented concern, we review the order, your photographs, the batch record, and any eligible independent assessment.

If a discrepancy is confirmed, replace the piece first, and find another resolution if replacement is not right.
