I made this necklace using five NATURAL colored cultured pearls that measure approximately 10mm in size -- they're floating on the 14K yellow gold plated over 925 sterling silver chain. The buyer will receive the EXACT pearl necklace pictured :). The cultured pearls have not been treated in any way, (no dye, no enhancement, no treatment, etc.); their colors are natural. The chain is 1.2mm wide and 14K yellow gold plated over 925 sterling silver. The necklace is 18 inches long, but can be adjusted to any shorter length. I include a small gold foil box in case the buyer is purchasing a gift :). I ship SAME DAY :). Thank you SO much for looking through my items!
