The first is that you should pay attention to the length to width ratio of the emerald cut diamond. This ratio determines the width and narrowness of the diamond.       Choose an emerald cut diamond with the length to width ratio lying between 1:3 and 1:6. This ratio provides the ideal shape of an emerald cut diamond, which is suitable for a ring setting. You must also understand that emerald cut diamonds have an elongated shape. For instance, wearing an emerald diamonds engagement ring can make your finger appear long and slender. Besides, these diamonds also make any inclusions visible and you should thoroughly inspect the stone before buying. It is better to go for clarity grades of VVS1 or VS1 as they tend to hide any interior defects or imperfections. These diamonds have step cutting, which means that they tend to have less sparkle compared to other diamond cuts. Their main advantage lies in the optical illusion that they provide, such as the hall of mirrors effect, and their affordable pricing.
