What is "jewel stone technology" and why is it used in hair styling tools?

Jewel Stone is a mixture of performance-enhancing minerals, including tourmaline, jade, opal, and titanium, with ceramic. Used in the body of heated styling tools, Jewel Stone emits far infrared heat, which penetrates the hair from within, resulting in faster dryer with less damage; and produces negative ions, which break up water molecules quickly, reducing drying time and locking in hair’s own natural moisture.
