Banded Agate
Mohs Scale 6.5 to 7
Named after the Aches River (now the Drillo) in Sicily, when discovered by ancient Greeks. Known as “Earth Rainbow” believed to protect against lightning, quench thirst and guard against evil spirits. A microcrystalline quartz (chalcedony) characterized by distinct; often concentric bands/stripes of varying colors and textures. Formed in voids of volcanic rock, with layers built over time by silica-rich water. A trigonal cryptocrystalline quartz with vitreous to waxy luster. Roman scholars prized it for healing and in many traditions it was used to ensure victory in battle and to protect travelers.
A grounding and stabilizing stone used to harmonize yin/yang and emotional, physical and mental imbalances. Believed to provide feelings of safety and security while enhancing concentration, perception and analytical abilities. Fosters courage and communication.
Due to its hardness and chemical resistance, coupled with its ability to take a high polish, banded agate has historically been used for laboratory equipment with knife-edge bearings for precision skill. Historically, Brazilian agate was used as a ship ballast. Used across cultures and eras for jewelry, carvings, intaglios, cameos and furniture inlay.
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: A more durable stone for everyday wear and use.
