This zultanite mood stone necklace made of 925 sterling silver chain and sensitive liquid crystal thermo mood color change hamsa hand.
When a person wears a mood necklace, the crystals inside the jewelry react to the body’s core temperature. When we are happy, feeling passionate or excited the body’s temperature rises. The wavelength and frequency of light then change causing a change in the perception of color seen on the jewelry. Similarly, when we are depressed, sad or have ‘a cold feeling in the heart’, the crystals twist in the opposite direction causing a different color of the necklace.
