Physical properties
Hardness: 6.5-7 (Quartz minerals), 3.5 (Abalone); Colors: Green, Teal, Black, Iridescent; Luster: Vitreous to Pearly; Structure: Trigonal/Amorphous
Formation & geological history
The quartz-based minerals (Bloodstone and Hawkeye) formed through metamorphic and hydro-thermal processes in crustal veins. The Abalone is biogenic, formed in marine environments.
Uses & applications
Primarily used for lapidary arts, jewelry components, cabochons, and metaphysical collecting.
Geological facts
This set includes Bloodstone, which was considered the 'Martyr's Stone' in the Middle Ages, and Blue Tiger's Eye (Hawkeye), which is a pseudomorph of quartz after crocidolite.
Field identification & locations
Includes Bloodstone (green with red spots), Blue Tigerseye (chatoyant dark blue), and Abalone (iridescent shell). Best identified by luster and characteristic patterns.
