This stunning fine jewelry ring features a substantial 10.18 carat cushion cut aquamarine center stone set in 18 karat white gold. The cushion cut, also known as a pillow cut, showcases the aquamarine's natural blue-green color with its large, open facets that maximize brilliance and light play.
Surrounding the center stone are 1.14 carats total weight of accent diamonds, adding sparkle and contrast to the serene aquamarine. The 18kt white gold setting (75% pure gold) provides a bright, modern backdrop that complements the cool tones of the aquamarine beautifully. White gold is finished with rhodium plating for enhanced durability and a brilliant white luster.
Aquamarine is the birthstone for March and a member of the beryl mineral family, prized for its clarity and sea-blue color. A 10+ carat center stone of this size is considered a significant gemstone and represents an exceptional value in fine jewelry.
