Shape Affects Price

The shape of a diamond can indeed affect its price, primarily due to factors related to the diamond's cut, demand, and the market.

Affect of Diamond Shape in Jewelry Price

Cut and Facets

The way a diamond is cut into a specific shape plays a crucial role in its price. The cutting process involves removing material from the rough diamond to create facets that reflect light and give the diamond its brilliance. Different shapes have different cutting requirements. For example, round brilliant-cut diamonds tend to be more expensive because they require a higher number of facets and precise cutting to maximize their sparkle.

Popularity and Demand

The popularity of a particular diamond shape can significantly impact its price. Round brilliant-cut diamonds are the most popular and sought after, which can make them more expensive. Other shapes like princess, cushion, and emerald cuts are also in demand, but less so than round diamonds.


The cutting process results in some material wastage. Certain diamond shapes result in more wastage than others, which can lead to higher costs for those shapes. Round diamonds typically have less wastage, making them more cost-efficient in terms of material use.

Carat Weight

The carat weight of a diamond, regardless of its shape, is a major factor in determining its price. Larger diamonds, regardless of shape, are generally more valuable than smaller ones. However, the size of a diamond in different shapes can look different, even if they have the same carat weight. For example, a round diamond often appears larger than a princess-cut diamond of the same carat weight.


Some shapes may require custom settings or designs in jewelry, which can add to the overall cost of the piece. Customization to accommodate specific diamond shapes may involve higher labor and material costs.

The shape of a diamond can affect its price due to factors related to cutting efficiency, demand, wastage, certification, and personal preference. It's essential to consider all these factors when choosing a diamond shape for your jewelry, as they can significantly impact the overall cost.
