An emerald-cut diamond is a glamorous choice for your engagement ring. A 2.5-carat emerald-cut diamond will measure about 9x7 mm, but this can vary depending on the stone's cut quality as well as its length-to-width ratio. Emerald-cut diamonds do not hide inclusions very well, so make sure to choose a minimum clarity grade of VS2 and view HD imagery of your diamond before purchasing it. If imagery is not listed on our site, be sure to contact us to request it. Since emerald-cut diamonds don't sparkle very much, choose a sidestone or halo setting if you want to add extra brilliance to your ring. Need help choosing the right ring? Contact us today.
