I made this necklace using a natural colored TAHITIAN baroque pearl that measures 10mm in width -- it's much longer. The buyer will receive the EXACT pearl necklace pictured :). The pearl has not been treated in any way, (no dye, no enhancement, etc.), so the color is natural. All of the metal I used is 925 sterling silver. The necklace can be worn at 16" or 18" depending on what loop is used for closure. 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!
