Physical properties

Hardness: 7 (Mohs scale); Color: Artificial teal/blue-green druze over clear/white quartz; Luster: Vitreous/glittery; Crystal Structure: Trigonal/Hexagonal druze; Cleavage: None (Conchoidal fracture)

Formation & geological history

Natural quartz geodes form in volcanic bubbles (vesicles) or sedimentary cavities where silica-rich groundwater precipitates over millions of years. This specific specimen has undergone a modern post-extraction 'enhancement' process where it is soaked in chemical dyes.

Uses & applications

Primarily used for decorative purposes, metaphysical collecting, gift shop souvenirs, and as educational entry-level specimens for young collectors.

Geological facts

While the geode structure and quartz crystals are millions of years old, the vibrant teal color is man-made. Natural quartz is rarely this specific shade of uniform blue-green; natural green quartz (Prasiolite) or Chrysocolla-druze is far more expensive and possesses a different crystal habit.

Field identification & locations

Identify by looking for 'pooling' of color in cracks or at the base of crystals, and check for an unnaturally vibrant hue that doesn't match the exterior matrix. To clean or test, a cotton swab with acetone may remove some dye.
