A tumbled finish can retain shallow pits or traces of original striation.

Material and appearance

Tourmaline group, intended schorl. The intended visual is black rounded schorl with subtle ridges and small pits. A rounded organic outline and a polished surface are the design, rather than a calibrated bead, cabochon or faceted gemstone. Pattern, translucency and shape can vary between pieces.

Identity and treatment

Ask for the tourmaline identity; black colour and surface lines alone do not authenticate it. The material identity and treatment statement should refer to the supplied batch. A representative image does not identify a specimen, verify an origin or establish an untreated condition.

Configuration and selection

The described configuration is one tumble-polished specimen. Compare packs or larger pieces only where the final offer lists those choices explicitly. Shape is irregular rather than calibrated. The design uses a proposed 20–30 mm length band; actual dimensions and net weight belong in the confirmed product specifications. No mining origin or laboratory certification is asserted without item-specific evidence.

Care and handling

Avoid drops; dry the surface after a brief wipe and protect existing fissures. Keep the pebble in its own soft pocket during transport. Keep small stones away from children and pets. Use as a decorative or study specimen; do not put minerals in food or drinking water or perform destructive home tests.

Buying questions

Will my stone match the photograph?

The supplied visuals represent the intended appearance. Actual stock can differ in shape, inclusions and pattern; compare the approved stock images and final batch specifications before choosing.

Is the material verified untreated?

Ask for the tourmaline identity; black colour and surface lines alone do not authenticate it.
