Use our diamond education to learn about Princess Cut, 1.2 Carat diamonds, and browse our broad selection of loose stones. Once you find the best stone for you, choose from one of our handmade ring settings and metal choices, including platinum and rose gold. All Ritani stones come with their own grading reports from the GIA or AGSL, complete with measurements, inclusion diagrams, and the details behind every 4C grade. For expert advice on your purchase, consult our non-commissioned virtual gemologist service or our skilled customer service team.
