Necklace is simple, bold and absolutely beautiful. Just one gorgeous Amethyst gem (20mm x 15mm) set in sterling silver bezel, attached to brightly polished silver necklace (16.5in). AFRICAN AMETHYST GEMSTONE is 15.6 CT; totally natural, with no color or other treatments. This fabulous gem is internally flawless and has amazing, intense rich purple color. They say that natural Amethyst makes “People Feel Happier”. I believe in it! It makes me happy, when I am looking at it.
