Description

The glassy dark surface contrasts with metallic hematite and fibrous tourmaline.

Material and appearance

Obsidian, natural volcanic glass. The intended visual is glossy black volcanic glass pebble with subtle grey reflections. 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

Natural obsidian is glass formed geologically; manufactured black glass is a separate material. 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 knocks and abrasion; a chipped edge can become sharp. 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

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?

Natural obsidian is glass formed geologically; manufactured black glass is a separate material.
