I came across an ad for this Amulette de Cartier necklace in a magazine, and was intrigued about the way it opens to, well … I’m not quite sure why it opens? The Cartier website offers a floral bouquet of marketing verbiage to tell you that it’s all luck related: Amulette de Cartier, an enchanting collection of precious bejeweled lucky pieces. Immersed with lightness and dreams, these precious talismans caress the skin. The contrast of materials unites the simplicity and elegance of its polished curves. The onyx or the white mother-of-pearl shine and focus the light of the diamond. The jewel closes like a padlock to hold luck and unlock your wishes.”

The piece shown below (it comes in several different metal and stone versions) is .27 total weight white diamond set into 18k white gold. The site says price is available upon request, which always makes me believe it’s more than I can afford.
