High Polished Druzy
The sparkle of druzy is amazing. The formation of the tiny crystals occurs after molten rock quickly cools, trapping gas within it as it solidifies. Gasses cause crevices and cavities in the cooling rock. Nutrient-rich groundwater later flows through these gaps and crevices, depositing layer after layer of minerals which crystallize on top of each other so the resulting encrustation is called druzy The process takes a few hundred or even a few thousand years.
