Platinum GIA Certified Opal & Diamond Ring, weighing 17.8 grams, centered by a GIA-certified 2.83 ct black opal measuring 12.93 x 8.93 x 3.69 mm (GIA #5231883453), displaying vivid blue-green play-of-color with striking depth. Accenter by 1.37 cts of diamonds (G–H color, VS1–SI1 clarity), the bold diamond surround and fan-like diamond accents create a dramatic, high-jewelry halo that amplifies the opal’s color from every angle. Finished as a size 8—a standout statement ring with coveted certification and undeniable presence. 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 Ring resizing or/and appraisal. This will carry an additional cost. Appraisals are made by our in house GIA certified Gemologist.
