Both round and square, cushion cut diamonds are both timely and timeless. Like Meghan Markle’s engagement ring, one carat cushion cut diamond rings update tradition and make it modern. Cushion cut diamond engagement rings are becoming more popular but you’ll find a much better selection and value if you buy a loose diamond and create your own one carat cushion cut diamond ring rather than buying a finished ring in a jewelry store. You can use ROSI, Rockher’s artificial intelligence enhanced by IBM’s Watson, to find the best quality and value one carat cushion cut diamond to fit your budget. Once you find the perfect diamond, our artisans in California will make the one carat cushion cut diamond ring of your dreams in your choice of recycled gold or platinum to fit you and your diamond. Making diamond rings one at a time from scratch allows us to craft every detail to last a lifetime.
