Use our diamond education to learn about 0.7 Carat loose diamonds and craft the perfect women's wedding ring she'll admire forever. Each of Ritani's responsibly sourced sourced loose diamonds comes with its very own GIA or AGSL certification report, detailing the diamond's 4C grades. 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. For expert advice throughout your shopping, you can question our gemologist or superb customer service team. We have partnered with local jewelry stores across the US so that you can see your loose diamond or engagement ring in person and try before you buy.
