Inspired by our classic Rectangular Signet Ring, this piece features an eye-catching baguette diamond that is flush set in the side of the rectangular bar. The band on this high-polished ring tapers down so it’s comfortable when you close your hand. Personalize this ring by engraving the top of the bar with a message, names, date, or symbol.\nWe can customize this ring with any finish, design, and any natural or lab-created stone. Contact us for a custom piece.\nNeed help deciding between Platinum and White Gold?
