Ritani sometimes has a great sale on diamonds and diamond jewelry. But even if not, Ritani already offers some of the lowest prices on lab-grown diamonds available anywhere. When they have a sale, you'll be able to save even more but you have to act quickly before the end of the sales. That said, we recommend Ritani regardless if they are having a sale since you won't find better prices and diamond quality anywhere else. See here if they're currently having a sale.
