The Heart Shaped Diamond Guide

By Devin Jones

Heart Cut Diamonds

Heart cut diamonds are a unique and romantic shape that offers more sparkle than most other fancy shapes. While beautiful to behold, heart shape diamonds are not one of the most popular diamond shapes. In fact, heart shaped diamonds are the 8th most popular diamond shape. Due to the lack of available inventory, it's a good idea to shop online at major online jewelers or using a search engine like StoneAlgo that aggregates diamond inventory from the top online jewelers.

Most Popular Color Grades for Heart Shaped Diamonds

Fancy cut diamonds vary widely in their ability to hide natural color that can occur in certain diamonds. Heart shaped diamonds offer a lot of sparkle and hide color fairly well, so buyers don't need to necessarily pay up for a colorless diamond (D - F grades). That said, most heart shaped diamond shoppers do tend to steer toward F and G color diamonds, which is a little pickier than other diamond buyers tend to be. The most popular color grade for heart shaped diamonds is G color as you can see in the chart below.

Most Popular Clarity Grades for Heart Shaped Diamonds

Heart cut diamonds tend to hide inclusions better than most other fancy cut diamonds thanks to their brilliant cut facet pattern. This pattern produces sparkle and flashes of brilliance that distract the eye from minor inclusions in the diamond. The most popular clarity grade for heart shaped diamonds is SI1 clarity followed closely by VS2 clarity.

Ideal Proportions for Heart Cut Diamonds

Heart cut diamonds are not given cut grades like round diamonds are, so it's important to understand which measurement are most desirable. The main factors to consider when choosing your heart shaped diamond are symmetry and the dimensions of the diamond such as depth percentage, table percentage, length, width, and surface area. When it comes to symmetry we always recommend Excellent grade but for the other criteria there are ranges that are more recommended than others.
