Platinum GIA Certified Conch Pearl & Diamond Necklace, weighing 5.4 grams, centered by a rare GIA-certified 3.94 ct conch pearl measuring 8.17 x 7.90 mm (GIA #5232882003), displaying a rich, warm coral-pink glow. Framed by 18 diamonds totaling approx. 0.50 ct (F–G color, VVS–VS clarity), the bright diamond halo and diamond-accenter bail add crisp, high-grade brilliance and elegant contrast. Finished on a 16-inch chain with a pendant measuring 0.75 inches in length—an exceptionally wearable, collector-level jewel with certification to match. Very good conditions. All our diamonds and colored gemstones are naturally earth-mined. Any synthetic (lab-grown) stones will be clearly indicated in the description. Upon Request, Auction House may provide an appraisal. This will carry an additional cost. Appraisals are made by our in house GIA certified Gemologist.
