Beatrice was always the queen bee. These are so fun. They are like the mood beads you remember but in more modern designs like this little bee pendant. The bead is made with thermo-sensitive liquid crystal that changes color with the varying temperature of your skin. The colors range from brown to purple and blues. I hand-wrapped the bead with burgundy Swarovski Crystals onto an 19" antique brass tone chain. The bead is usually purplish at room temperature and turns greenish brown at cooler temps. Please note: These beads should not be submerged in water.
