Why Round Cut Diamond Engagement Rings Are More Expensive


Every diamond buyer wants the brightest stone and the round brilliant cut is known as the brightest shapes. That is the reason why women prefer a round brilliant diamond as the centerpiece of their engagement ring. According to a study, more than 75% of rings sold in the market are round cut engagement rings. Although the round brilliant cut is more popular than any other shape, popularity is not the main factor driving up the price of the stone. In fact, it takes a larger rough diamond to cut a round brilliant diamond than any other shape. There is a greater loss of rough stone when cutting a round shape, so the cost of each round cut carat is relatively higher than any other shape. This is the main reason why round cut engagement rings are more expensive. However, the increased demand for a round cut plays a secondary role in the escalation of its price.

Performance of rough stone

When mined, most of them are not perfectly shaped, so experts try to make the most of every rough stone they obtain. Elegant shapes can be drawn from an irregularly shaped rough stone, but a round brilliant diamond can be cut from a rough diamond block to the proper shape.
