Use our diamond education to learn about D Color loose diamonds and build the perfect custom ring she'll marvel at forever. Every loose diamond from Ritani comes with a report from the AGSL or GIA and is ethically sourced. After you select the stone that's right for you, complete your ring with a style from our diverse selection of ring settings, from simple solitaires to sparkling Art Deco-inspired halos. If you need help along the way, you may engage with our customer service team or virtual gemologist. When you've chosen your diamond or wedding ring, you can select to preview it in-person, for free, at one of our US based, local partner jewelers, from Los Angeles, CA to New York City.
