Oval-shaped diamonds are increasingly popular in engagement rings, and a 2.5-carat oval-cut engagement ring will make a standout choice. A 2.5-carat oval cut diamond will measure approximately 10x8 millimeters, but this can vary depending on how well the stone was cut and its length-to-width ratio. Make sure to choose an oval-cut diamond with a Very Good cut grade. You should also seek out diamonds with excellent polish and symmetry grades for maximum sparkle. If a 2.5-carat diamond is out of your budget, you may want to consider a lab-grown diamond instead. Need help choosing the right diamond? Contact us today.
