April Birthstone Jewelry: Diamonds

Our selection of diamond April birthstone jewelry spans the wide range of diamond jewelry available today, from classic diamond high-jewelry from Harry Winston, the King of Diamonds, to demi-fine jewelry that perfectly expresses your unique style. 

Harry Winston

The Winston Cluster has been an icon for Harry Winston — and the jewelry world — since it debuted in the 1940s. Mr. Winston decided to place diamonds at different heights and angles, bringing in more light and increasing their sparkle. This high-jewelry necklace features 195 pear- and marquise-cut diamonds.

G by Glenn Spiro

Glenn Spiro is a London-based gemstone dealer and jewelry designer who specializes in exquisite stones. This ring features an exceptional 10.01-carat, D-colored, internally flawless, Type II A marquise-cut diamond. Type II A diamonds are the purest diamonds that exist, so a diamond of this size, color, and clarity is a rare find. The old mine diamond is set in 18K red gold and bronze, an unusual metal choice for a stone of this quality, and there are pavé diamonds that trim the shank.

Anita Ko is known for her stunning diamond jewelry. She brings her unique design aesthetic to classic pieces, like this eternity band, which she makes modern and chic by using diagonally set diamonds.
