Care
Due to its cleavage, brittleness, and low hardness, fluorite is too fragile for most jewelry use. Ring use isn’t recommended. However, protective settings, occasional wear, and use in pendants and earrings can let you show off these beautiful gems. Some specimens may fade with prolonged exposure to light, so store any fluorite jewelry out of the light. In addition, store them separately from other harder gemstones to prevent contact scratches.
