I love the colors in this beautiful, showstopper ring! The Caribbean blue quartz triplet oval-cut gemstone is awesome. The color of the quartz is neon blue, and it is huge--9.91 ctw (16mm x 12mm). The gemstone is surrounded by a halo of 16 sparkly beautiful 2.5mm white zircon gemstones and on each side is one 7mm x 5mm pear African lilac quartz stone. This size 7 ring is made from solid sterling silver that has been plated in platinum for added strength and tarnish protection. It is stamped 925 and signed. If you love a bold statement piece, this might just be the one for you!
