Emerald cuts typically do not command a higher price compared to other diamond cuts solely based on their shape. The price of a diamond is primarily determined by its carat weight, color, clarity, and cut quality. However, it is important to note that the length-to-width ratio of an emerald cut can affect its appearance and value. A well-proportioned emerald cut with a desirable ratio may be more sought after and therefore more expensive compared to one with less ideal proportions.
