Physical properties
Hardness: 7 on Mohs scale; Color: Translucent orange with internal fracturing; Luster: Vitreous; Crystal Structure: Trigonal/Hexagonal; Specific Gravity: 2.65
Formation & geological history
This is a natural clear quartz crystal that has been 'crackle' treated. The process involves heating the quartz to high temperatures and then rapidly cooling it (quenching) to create intentional internal fractures, followed by dyeing to achieve the orange color.
Uses & applications
Primarily used for decorative purposes, jewelry making (beads and pendants), and in metaphysical practices as a 'healing stone'.
Geological facts
The 'crackle' effect is a form of thermal shock. While the base material is a natural mineral formed over millions of years, the aesthetic finish and color are the result of modern human intervention.
Field identification & locations
Identified by its tell-tale network of fine internal cracks and vibrant, often non-natural dye distribution concentrated within those cracks. Common in gift shops and crystal collector starter sets.
