I'm going to talk a little bit about marquis diamonds. They're another member of the brilliant cut family. Marquis' are definitely not very popular for engagement rings anymore or at least not as a solitaire setting, but if you do have your heart set on it, a marquis could look interesting when it's set East to West instead of North to South in a very more contemporary setting. Marquis' make beautiful side stones and diamond bands.
As you can see this beautiful vintage marquis diamond band I have here and earrings that create this lovely floral pattern. Marquis' tend to have a bow tie effect similar to a pear shape and an oval and this is just due to the cutting process so you want to make sure there's not a real dark spot in the center of the stone. Also, it's really important to pay attention to the proportions because each stone is cut differently. So, you don't want something that's too long and thin or too fat in the middle. You want to get just the right pleasing proportions so that it'll look nice on the finger. So, those are just a few things to consider if you love a marquis shaped diamond.
