When wearing a ring that features a heart shaped diamond, gems should be big enough that people will notice all of its special characteristics. Let's take a look at what carat weight is best for this particular diamond shape.

Of all the traditional diamond shapes, hearts are the most elaborate. Representing less than two percent of all diamonds on the market, they feature rounded curves, a delicate point, and a sparkling array of carefully placed brilliant-cut facets. All of this detail is something that you definitely want to show off!

Heart Shaped Diamonds Are Meant to Be Celebrated

Unlike other cuts like rounds and pears which are neutral, the heart shape has a very specific association with love. Whether that be the connection between family members, partners, dear friends, or even self-love, purchasing and wearing a ring that features a heart shaped diamond is a deeply intentional choice. 

To ensure that people can appreciate your diamond heart, it makes sense to prioritize carat weight in your budget. Especially small gems, such as those weighing less than half a carat, may not be big enough for viewers to pick up on their shape. 

This 0.30 ct diamond is pleasantly petite, but you may have to lift your hand to show that it is a heart.

The Perfect Carat Weight for a Heart Shaped Diamond Set in a Ring

If you really want your heart shaped diamond ring to be admired, aim for a gem that is at least half a carat. Such gems have a width of about 5 mm and are small enough to be considered dainty and discrete while being big enough that people can recognize their outlines.

If you are looking to invest in a big gem, the sky is the limit! Heart shaped diamonds have a similar depth as round and oval shaped diamonds, meaning that even gems with a lot of carat weight will still sit low on your finger minimizing the risk of snagging.
