Smoky Quartz
Mohs Scale 7
A durable form of quartz that forms when natural radiation from surrounding rock interacts with trace amounts of aluminum, changing the crystal's color over millions of years. It has been known in use for over 2000 years, with early use as sunglass lenses in China, and kilt pins and dagger handles in Scottish Highlands. Ranging in color and transparency from dark brown opaque to light yellow-brown and translucent. Smoky quartz is a silicon dioxide with a hexagonal (trigonal) crystal system.
Variations include the deep brown to black Morion, and a vibrant yellow-brown variant named after the Cairngorm Mountains in Scotland. Rutile (needle like inclusions) may occur.
Known as a powerful protection stone, smoky quartz primary function is grounding and stability. Used as a shield against EMF, emotional stress, negative energy and aid in turning negative, fearful or anxious emotions into positive, actionable energy.
Popular in jewelry, carving and adornments, smoky quartz is also used in countertops, floor tile and decorative wall panels. Due to its hardness, low grades are used as an abrasive in sandblasting, and in the production of glass, ceramics and foundry molds. Due to its ability to vibrate at precise frequencies it is prized for watch and clock instrumentation.
Use & Care
Use: Last On, First Off: Apply all lotions, perfumes, and hair/body sprays before putting on jewelry to prevent chemical buildup that can dull and damage the surface. Activity Check: Remove jewelry before swimming (chlorine), showering (soap residue and chemical exposures), or high impact activities like exercise or gardening to avoid damage. Chemical Exposure: Avoid household cleaners, alcohol-based sanitizers, and vinegar, which can alter appearances permanently.
Cleaning: Method: Use lukewarm water and mild (detergent free) soap. Action: Gently rub with a soft cloth. Drying: Crucial. Immediately pat dry with a soft lint-free cloth. Do not air-dry, as residual moisture can damage porous stones over time. Avoid: Never use ultrasonic or steam cleaners, which can cause fractures and strip some colors.
Storage: Individual Separation: Store each piece in its own soft pouch or a lined compartment to prevent stones and metals of varying hardness scratching each other. Environment: Keep in a cool, dry place away from direct sunlight. Moisture Control: Consider adding silica packets to storage containers to absorb excess humidity that can tarnish metals and affect stones over time.
Longevity: durable, yet sensitive to heat, which can fade or lighten color.
