How A Diamond’s Shape Impacts Value

Posted on February 25th, 2021 by Joe G

Did you know that there’s a direct correlation between the shape of your diamond and how much it’s worth? Our diamond dealer in Chicago sees a wide range of diamond jewelry in all shapes and sizes.


If you’re on the hunt for the perfect diamond engagement ring and you want to purchase a piece of jewelry with the most value, you can consider the shape of your diamond as a means to the final cost.

While Round Brilliant Cut is the all-time biggest seller, some of the most popular diamond fancy shapes include:

  • Pear
  • Oval
  • Princess
  • Cushion
  • Marquise
  • Emerald
  • Radiant
  • Heart
  • Asscher

The Diamond’s Shape vs. Diamond’s Cut

Be mindful of the difference between a diamond’s shape and a diamond’s cut. Its shape refers to the actual outline of the cut. Like fancy-shaped Marquise, Oval, For example, emerald cut diamonds are usually rectangular in shape yet have fewer facets than other fancy shapes. Desirable proportions for an Emerald cut are longer than it is wider versus a square for a true Emerald-cut look.


The diamond’s cut refers to properties such as faceting, symmetry, polish, and proportions. A diamond that is too deep or too shallow is not as desirable.

The Impact of Shape on Your Diamond’s Value

Here are some factors to consider before buying diamond jewelry.

Market Popularity

Custom designs are beautiful, and one should always choose which shape they have always desired and what they love just like art. When buying a diamond I don’t think one is thinking of selling it, but if you want to sell your diamond, there are shapes that command higher values than others as far as secondary market values. At one time (mid-1960s and late 1980s/early 1990s) Marquise was 15 to 20 percent more than other diamond shapes. Ovals are popular right now. Diamond trends come and go. The most popular diamond shapes are still round.

The Diamond’s Cut and Proportions

In addition to how popular a particular shape is, how well the diamond is cut will also impact its value. If there are asymmetrical aspects to the stone or the length-to-width ratio is even a little bit off, this will have an impact on how much your stone is worth. Also if the diamond exhibits fluorescence it will affect the value.

Customer Testimonial

Had a Great Experience

I have dealt in coins and metals since the 80s. Had dealings with many dealers. Got scammed by a few. Chicago Gold is the only one I would recommend to my family or friends. Have your valuables appraised by them before you sell.

I'll be back

Cashed in some silver coins and received a very fair exchange. Joe and Chris, were very friendly, and comfortable to deal with. Came back with some jewelry, and received a rough appraisal...again no pressure.
