The Cave Pearls vary in size and shape. You can find small pearls and big clusters. They form slowly as calcite crystals build up. The water drips or seeps through cracks, laying down layers of calcite.
Illuminate them, and they shine brightly. The pearls’ smooth surfaces reflect light in a stunning way. This beauty catches everyone’s eye.
