If you like the brilliance of a brilliant cut diamond and the long shape of a marquise or emerald cut diamonds, the oval cut diamond is for you. This stunning long rounded shape is comprised of 58 facets and for best results, an ideal length to width ratio is between 1.33 and 1.66. The long shape of the diamond allows it to optimize carat weight, as the stone has the tendency to appear larger than round shaped diamonds. The oval shape also has the effect to elongate shorter fingers. It’s recently become popular for the diamond to be set in engagement rings, especially if they are flanked with two side diamonds to create a three stone diamond ring. We also think the shape of the stones looks perfect set in diamond stud earrings. Although the cut seems quite modern, it was actually invented in the early 1960s by the famous Russian diamond cutter Lazare Kaplan.
Our Expert Advice on Oval Shaped Diamonds
The most important factor of an oval diamond it its length to width ratio. This is due to the “bow-tie effect” which is all about the light dispersion within the stone. As a minimum we recommend a ‘good’ cut grade, G colour grade and an SI2 clarity grade – meaning that any flaws or inclusions in the stone will only be notable through magnification. This image below shows all 58 facets the diamond is cut into from the rough, which is why the diamond has such stunning brilliance and sparkle.
