Depending on how well you know your intended bride, it may come as no surprise to you that the oval-cut diamond is a cut fit for a princess. In fact, oval-cut diamonds have a history of gracing the hands of royals. Think Lady Diana, who chose her own engagement ring — an oval-shaped blue sapphire, surrounded by diamonds. Today, that same ring is worn by Kate Middleton, wife of Prince William. While the love of your life is not likely to be sitting on a throne any time soon, that doesn’t mean you can’t treat her like the queen she is with a stunning oval-cut diamond engagement ring from Costco!
