The original Keystone silhouette, reimagined with four bezel-set diamonds across its sculptural gold face. Featuring UbyKate’s proprietary Tri-Cut alongside pear, oval and round-cut lab-grown diamonds, each stone brings its own brilliance and character to the design.

A generous gold dome and crisp central ridge create the signature Keystone profile, while four individually bezel-set diamonds introduce a considered balance of bold gold and light. The result is a substantial diamond ring with a strong architectural presence and plenty of room for its own meaning.
