Due to its softness, perfect cleavage, and light sensitivity, this gem makes a better collector’s item than a jewelry piece. Celestites also have great heat sensitivity. Since jeweler’s torches can easily exceed 200° C (392° F) and cause the stone’s?colors to fade, be wary if you take a jewelry piece to be repaired. Consult our gemstone jewelry cleaning guide for more recommendations.
