Heat Sensitive Crystals: Essential Care Tips and a Complete Guide
Certain crystals, including selenite, fluorite, malachite, opal, and many more, are sensitive to heat and can be damaged when exposed to high temperatures. These crystals may crack, lose their color, or become brittle, making proper care essential to maintaining their beauty and energetic properties.
A Deep Dive into Heat-Sensitive Crystals
Crystals are cherished not just for their beauty but for their healing and metaphysical properties. However, not all crystals are resilient when exposed to heat. Some stones are particularly sensitive to high temperatures, which can alter their structure, appearance, or energy. If you’re using crystals in meditation, healing, or even just as part of your décor, knowing which ones are heat-sensitive can help you take better care of them.

General Guidelines for Heat-Sensitive Crystals
A good rule of thumb is that any crystal with vibrant colors, high water content, or a softer, more brittle structure may be more sensitive to heat. Even hard crystals like quartz can sometimes be heat-sensitive if they have been treated or contain natural inclusions.
If you are unsure whether a specific crystal is heat-sensitive, it’s safest to avoid exposing it to high temperatures or direct sunlight. When in doubt, store crystals in cool, dry places and avoid placing them near heat sources.
- Avoid Direct Sunlight: Many heat-sensitive crystals can fade or crack when exposed to strong sunlight. Store them in shaded areas.
- Handle with Care: Avoid using hot water or cleaning solutions that may generate heat.
- Cool Storage: Keep heat-sensitive crystals in a cool, stable environment, away from heating sources like radiators or electronics.
