I made this necklace using three Edison cultured pearls that measure 10.5mm to 12mm in size. The buyer will receive the EXACT pearl necklace pictured. The pearl's colors are natural -- no treatment, no dye, no enhancement, etc., and they have high metallic luster. The chain is 14K yellow gold plated over 925 sterling silver, (stamped "925"). The length is 18 inches, but it can be adjusted to any shorter length. I include a small gold foil box in case the buyer is purchasing a gift, and I do ship SAME DAY :). Thank you SO much for looking through my items!
