Very Good Condition Authentic Size 6.5 $5,795 Roberto Coin Ipanema Collection 18K Yellow Gold Multicolor Bold Gemstone Amethyst, Prasiolite ( Green Amethyst ), Lemon & Smoky Quartz Wide Band Cocktail Ring WITH SIGNATURE RUBY Wide band (11-21 mm) ring set with 3 big gemstones: pear smoky quartz, round mint green prasiolite or green amethyst, convex-sided square lemon quartz; small oval purple amethyst & 7 small round amethysts scattered across the band. It takes up the first joint of the finger- a very bold, modern-looking piece! Entire stone arrangement is 25 mm (approx 1") wide, 21 mm tall. Band bears some wear, but doesn't have deep scratches or bends. Stones are in perfect condition. The 3 bigger stones: pear smoky quartz table 14 x 10 mm, lemon quartz in a fancy convex rectangle 12 x 12 mm across the table, round greenish aqua prasiolite12 mm diameter. Small amethyst is 7 x 5 mm oval. All of these stones' tables are checkerboard faceted and prong set. All eye clean and transparent. 7 accent amethysts are set into the band, in between and flanking the larger stones and are 3 mm round brilliant cut. Size 6.5 verified on a mandrel. The prasiolite stone extends below the band toward the finger when worn, and pushes snugly against the prongs. It doesn't bother me when being worn; I believe it was designed that way to accommodate the cut of the stone. You can see this in Photo 5.
