Red Jasper (beads)

Hardness: 6.5-7 on Mohs scale. Color: Opaque red to reddish-brown, often with swirls or flecks of other colors. Luster: Dull to vitreous (glassy). Crystal Structure: Trigonal (microcrystalline). Cleavage: None. Specific Gravity: 2.58-2.65. Fracture: Conchoidal. The beads show a polished, smooth surface, and uniform dark red color, typical of processed jasper.

Red Jasper forms as a chemical sedimentary rock, often in association with volcanic activity. It originates from the precipitation of silica from solutions, sometimes replacing other minerals or organic material. The red color is due to high iron oxide (hematite) content. Geologically, it can be found in formations ranging from Precambrian to relatively recent periods.

Red Jasper is widely used in jewelry (beads, cabochons, carved items), ornamental objects, and as a decorative stone. It is also collected by mineral enthusiasts. Historically, it was used for tools and seals. The beads in the image are clearly prepared for jewelry making.

Jasper is a cryptocrystalline variety of quartz, meaning its crystals are too small to be seen without high magnification. It is known for its wide range of colors and patterns, with red jasper being one of the most common and recognizable. Ancient civilizations valued jasper for its beauty and believed it had protective and healing properties. The word 'jasper' means 'spotted stone', though not all jasper varieties are spotted.

In the field, raw red jasper often appears as massive, opaque, fine-grained material, typically occurring in sedimentary beds or as vein fillings. Its hardness (cannot be scratched by a knife) and characteristic red color are key identifiers. It's commonly found worldwide in areas with silica-rich water and iron-bearing sediments, including the United States (e.g., Oregon, California), India, Russia, and Egypt. For collectors, massive samples with interesting patterns are prized. The image shows processed beads, which are easily identifiable by their spherical shape, drilled holes, and polished surface.
