Cold-Averse Gemstones

With possible record breaking cold temperatures looming in our near future, we thought we would take the time to make note of a few gemstones that should be left safely at home during these frigid days.

Certain gemstones are sensitive when it comes to rapid temperature change, meaning that these gems can fracture when worn or carried from the warm indoors to the freezing cold outside. Prolonged exposure to extreme cold can also cause the inclusions inside certain gems to expand or contract, leading to internal fractures. This means that you should absolutely avoid leaving these gemstones/jewelry in your car for an extended period of time while it’s cold outside.

So which gemstones are the most prone to cold weather and sudden temperature changes?

  • Opals
  • Emeralds
  • Tanzanites
  • Moonstones
  • Aquamarines

You should also consider avoiding wearing other gemstones such as topaz, quartz, garnet, and tourmaline, as these have been known to be adversely affected by cold temperatures (although to a lesser degree) as well. Similarly, any heavily included gemstones should be left at home during bitter cold days.
