Short-wave UV geodes from Sonora, Mexico. These pieces hold botryoidal chalcedony that lights up under short-wave UV. Each geode is closed and uncracked. Hollow interiors are not guaranteed. Every piece is unique.
These geodes can show fluorescence from minerals like chalcedony, fluorite, calcite, and willemite. Colors can range from green to blue to purple depending on the minerals inside. They have mixed quality across the lot, giving you a natural variety that collectors enjoy.
Color: Fluorescent colors vary. You may see green, blue, purple, or mixed tones under short-wave UV. Hardness: Common minerals inside include quartz-family material, usually around 7 on the Mohs scale. Clarity: Interiors range from translucent chalcedony to more opaque structures. Luster: Expect a glassy to waxy luster depending on the surface and mineral mix. Density: Weight varies based on mineral content.
Metaphysical properties: Many people use chalcedony geodes to support calm energy, emotional balance, and steady grounding. Collectors also use them in meditation spaces for peaceful focus.
Care tips: Keep the geode away from harsh cleaners. Wipe gently with a dry or slightly damp cloth. Store away from long periods of sunlight to protect any natural color. Use a proper short-wave UV lamp for best fluorescence.
