Here's a little about the crystals:
Natural, color-change gemstones are "phenomenal gems" which display a distinct change in perceived gem body color when viewed under different types of lighting. According to the Gemological Institute of America (GIA), these rare, "phenomenal gems" display special effects that defy simple description. Color change occurs due to the unique crystal structures of a gemstone, the process of selective absorpsion of light rays (how a material absorbs some components of visible light and returns others), and how humans perceive color and light.
The crystals in the necklace was photographed using two different light sources to show the color change (CLEAR = fluorescent light, PURPLE = incandescent light). The colors in the pictures very closely resemble the true colors you will see in person.
The crystal turns purple under incandescent lighting due to small amounts of chromium and vanadium, minerals that absorb all colors except purple. A gemstone reflects a certain color because that gemstone does not absorb that particular color in the light spectrum. For example, the crystal will absorb all colors on the light spectrum except purple, making it reflect that color.
