Physical properties
Hardness: 6-7 (quartz-based) to 6-6.5 (pyrite); Colors: orange, green, grey, and metallic gold; Luster: Vitreous (polished) to Metallic (pyrite); Structure: Trigonal/Cubic.
Formation & geological history
Most are chalcedony varieties formed in volcanic cavities or sedimentary environments; Pyrite forms in hydrothermal veins or sedimentary deposits. These are processed through mechanical tumbling.
Uses & applications
Jewelry, pocket stones, decorative accents, metaphysical collections, and educational kits.
Geological facts
This collection includes 'Fool's Gold' (Pyrite) which was often mistaken for real gold due to its metallic luster and yellow hue. The banded orange stone is an Agate, which has been used for talismans for over 3,000 years.
Field identification & locations
Identify Agate by its characteristic banding; Pyrite by its metallic sheen and heavy weight; Aventurine by its shimmering 'aventurescence'. Commonly found in gift shops and rockhound starter kits.
