Hand stamped Hope aluminum disc (stamped on one side) and dangle dark gold round, faceted Apatite bead all on a Stainless Steel chain. All rings, oval extender chain and lobster clasp are Stainless Steel. Disc is 1/2 inch in diameter; Apatite is 4mm Necklace chain is 18 to 20 inches long Note: All pearls/stones may slightly vary in color, shape, and size because they are real/natural pearls/gemstones. Some may have been dyed or heated to enhance their color. I do my best to match all pearls/stones for color, pattern, shape and size. All pictures are taken in natural light. Colors may vary slightly when viewed on different screens/devices.
