Description from Oldmine when I got the ring: This is an aquamarine and diamond ring set with an emerald-cut aquamarine flanked by two emerald-cut diamonds, mounted in platinum. Aquamarine measure app. 15.94×13.36 mm. It’s natural and stunning, and the cut is perfectly done. The diamonds on the sides are excellent quality, and weigh approximately 0.12 carats in total. The ring is super heavy on 8 grams! But stays on top of the finger with great balance. Condition: great condition with very gentle sign of wear (I wore it only a few times in the last couple years for special occasion)
