This stunning platinum ring features a 3.90-carat cushion-cut green/blue tourmaline center stone, celebrated for its rare and vivid teal-to-blue-green color reminiscent of Paraiba-style hues. The cushion cut's softly rounded corners and large facets maximize the stone's natural brilliance and depth of color.
Surrounding the center stone are 0.66 carats total weight of accent diamonds set in platinum, a premium precious metal prized for its durability, natural white luster, and hypoallergenic properties. Platinum's density and strength make it an ideal setting for securing precious gemstones.
Tourmaline is a naturally occurring semi-precious gemstone available in a wide spectrum of colors. The green/blue variety — sometimes called indicolite or blue-green tourmaline — is among the most sought-after in the tourmaline family. This ring is a bold, elegant statement piece suitable for special occasions or as an engagement or right-hand ring.
