Which Crystals are Safe in the Sun?
Unfortunately, some crystals fade or can even break/crack when they are in the sunlight for extended periods of time. It is a good idea to make sure your crystal is safe in the sunlight before you put your crystals in direct light for a long period of time. Some crystals are okay for a little while, while others will react immediately in sunlight.
