This sterling silver ring is a unique and visually striking piece of jewelry and is definitely a statement piece! It is made from solid sterling silver plated with platinum for durability and tarnish prevention. The center stone is a huge 18mm x 13mm yellow green Ouro Verde quartz that is double pronged on all four edges for security (11.92 ctw). On the sides and down the shank is a perfect butterfly design with four marquise-shaped natural chrome diopside stones and four round ones (0.91 ctw) accented with gold vermeil on each side of the size 9 ring. The gallery of the ring is smooth and slides easily over the finger. The ring is stamped 925 and signed. Ouro Verde quartz is a rare and unique color variety among quartz. The stone is exclusively found in Brazil’s Bocarica mine.
