Thanks for that Firefly. I haven't come across actual gems in creams before. Not sure how it would work!
Here's what they say about it in the blurb
"Be a gem. DHC Tourmaline Pack uses the naturally energizing potency of tourmalines. Micro-fine particles of this precious gem delve deep down into pores to absorb imbedded dirt and impurities. The result is improved clarity and renewal. Help find relief from the skin-damaged look of UV rays, dryness, stress, and environmental pollution. Get ready to amp up your complexion with this vibrancy-evoking mask."
I don't know if I want bits of stone in my pores...
You could make your own gem cream by making an essence of the gemstone & adding it to a basic face cream. Not abrasive, but it would contain the properties of the stone.
I'm expecting the thermal underwear catalogues to arrive now I'm 40
