Nothing endures but change.  (Heraclitus) The mood stone is back! This minimalist necklace features a sterling silver bezel set mood stone (25x18mm) on a sterling silver chain. Mood stones are man made.  They react to body temperature (or mood) and go from a deep Lapis blue color through a variety of hues to an icy grey moonstone color at its coldest. – See more at: http://brackendesigns.com/product/mood-stone-necklace-sterling-silver-changing-color-pendant#sthash.XzZ44agU.dpuf
