How Diamond Shapes Affect their Value

Posted by Guest Contributor

Diamonds are composed of compressed carbon, they are unique and different in terms of their shapes, sizes and colours. If you are thinking about how to sell your diamond rings, then there are a few things about diamond’s external and internal characteristics you should know. All diamonds have a specific value attached to them, but you must know how to calculate the exact worth of your diamond jewelry based on such characteristics.

In this blog, we are going to shed some light on how a diamond’s characteristics and shapes can have a direct impact on its overall value.

The 4 C’s

If you want to sell your diamonds, you must know about the 4 C’s. Industry professionals follow a set of guidelines that allows them to assess the quality and value of a diamond. They include the following:

  • Carat

Carat is the unit of diamond’s weight measurement. 1 carat is equal to 200 milligrams. A heavyweight diamond will have a higher price value.

  • Color

Although the most common color for a diamond is white. There are a bunch of other color options available including blue, pink, gray, brown, black, and yellow. Diamonds with more clarity and carat usually have slightly more value than other colored diamonds.

  • Clarity

A diamond’s purity is defined in terms of its Clarity. Fewer internal flaws and marks can increase your diamond’s worth.

  • Cut

The setting of your diamond ring and its total carat weight also determines its value. If there are large individual diamonds, their value will be much higher than smaller diamonds.


In the diamond industry, the pricing of diamond jewelry depends on two factors- Market Desirability and the Condition of the Diamond. When talking about specific shape diamonds, round cut diamonds are in the most demand. So, if you’re planning to, ‘sell my diamond,’ your round diamond jewelry is more likely to have a higher resale value as compared to other fancy diamond shapes because it offers:

  • A Highly Versatile Appearance
  • Exceptional Brilliance
  • Timeless Design
  • Stunning and Beautiful Look

Two Important Factors


To calculate the exact value of your diamond, how popular your diamond’s shape is on the market speaks volumes. If the shape is popular, you can fetch more resale value. Some of the most popular diamond shapes are- Round, Princess, Emerald, Marquise and Cushion.

Another factor is the diamond’s cut. People who want to sell diamonds need to determine what type of diamond cut they have. As every diamond jewelry has a specific desirable ratio, you need to evaluate the symmetry and cut grade of your jewelry.

Examples of some of the most coveted ratios are as follows- Round shape length to width ratio is somewhere between 1 to 1.02 length to width ratio, while the ratio for the Cushion shape would be around 1.00 to1.10. The length to width ratios for Princess and Marquise shapes are 1 to1.05 and 1.75 to 2.00 respectively.
