A softly structured take on a timeless classic. The Ellie Cushion features a lab-grown cushion-cut diamond framed by slender prongs for maximum light return. Designed to balance vintage romance with modern minimalism, this ring is all glow and quiet strength.
Design Notes: Handcrafted in 9ct, 18ct, or platinum. Each IGI-certified diamond is set to highlight the cushion shape’s soft corners and brilliant facets.
Style Tip: Pair with a pavé or plain gold band to create a stack that transitions effortlessly from day to night.
All stones above 0.50 ct come with an official certificate. Our lab-grown diamonds are graded by the International Gemological Institute (IGI), detailing cut, clarity, color, and carat for complete confidence in your piece. For natural diamonds, available on special request, certification is issued by the Gemological Institute of America (GIA). Every certificate is a mark of authenticity, integrity, and lasting value — learn more under Certification.
