Physical properties

Hardness: 5-6 (Mohs); Color: Dark grey to matte black; Luster: Sub-metallic; Structure: Manufactured interlocking links; Highly malleable/ductile metal.

Formation & geological history

Modern industrial manufacturing. Metals are extracted from ores (like Hematite for iron or Chalcopyrite for copper) and alloyed through smelting and refining, then shaped and chemically oxidized.

Uses & applications

Used primarily in jewelry and fashion accessories. Darker finishes are popular for 'antique' or Gothic aesthetic jewelry styles.

Geological facts

This item is a manufactured rope-style chain rather than a natural geological specimen. The black finish is usually achieved through chemical patination or physical vapor deposition (PVD) coating.

Field identification & locations

Not a field-identifiable rock. Can be tested with a magnet to determine iron content (steel) or by weight and streak to identify base metals under the plating.
