This cat ring contains liquid crystals, thermochromic elements that change colors based upon the temperature of the finger of the wearer. Quite often, our body temperature changes as our mood does, showing different colors when we're happy, anxious, excited, sad or relaxed, for example.
And whatever the state, seeing them change colors is a very eye-catching, almost hypnotic effect!
This is perfectfor you, or as a giftfor a loved one.
