BUYER'S GUIDE TO HEART SHAPED DIAMONDS
Like a brilliant valentine that lasts forever, heart shaped diamonds are a grand gesture of romance. But true love isn’t easy. The heart is the most difficult of all diamond shapes to cut. Each is drawn by hand to solve a difficult challenge, like an unusually shaped diamond rough with a large inclusion or notch near one edge. When it succeeds, it’s a brilliant tribute to love.

The History of Heart Shaped Diamonds
The heart shape diamond first enters history in a letter written in 1463 by the Duke of Milan, Galeazzo Maria Sforza. He describes a heart shape diamond as a rare treasure only the most determined seekers can possess.
In 1458, a Flemish diamond cutter named Lodewyk van Berquem had just discovered that he could cut diamonds with more precision than even before by grinding them with diamond dust. He soon cut the first pear-shaped diamond. The stage was set for the first heart diamond cut: a wide pear shape with the addition of the cleft indentation of the heart.
Less than a century later, Queen Elizabeth sent Mary Queen of Scots a heart shape diamond as a gift of friendship.

How to Buy Heart Shaped Diamonds
Heart shaped diamonds are the most difficult of all diamond shapes to buy too. Why is that? Think about the complexity of the shape: the cutter needs to beautifully curve the sides, create graceful and symmetrical lobes and then a deep (but not too deep) cleft. The outline of each heart is slightly different and there are a lot of things that can go wrong. That’s why you’ll have to look at a lot of heart shaped diamonds before you find one that is the perfect shape.
When we look at historical heart shape diamonds, they don’t have the valentine shape we see today.
Antique heart-shaped diamonds have almost no clefts. The Queen’s Heart, Marie Antoinette’s 5.34-carat blue diamond, is more like a pear shape than a heart.
The famous Blue Heart Diamond in the Smithsonian Institution, cut in 1910, also has a very shallow cleft. So does Queen Elizabeth’s Cullinan V, the heart shaped diamond cut from the world’s largest gem quality rough diamond in 1908.
Modern heart shape diamonds didn’t appear until later in the twentieth century, becoming popular in the 1950s, when this difficult cut was perfected. True love takes time.
Heart Shaped vs Pear Shape
vs Oval Diamonds
vs Oval Diamonds
The two cuts that are most similar to a heart shaped diamond are the pear shaped diamond and the oval shaped diamond.
Pear shaped diamonds are as dramatic as heart shapes. They have a very similar shape except for the cleft but pear shapes are more elongated with a finger-lengthening effect. Unlike heart shapes, which have a top and bottom, pear shaped diamonds can be worn either with the point up or the point down.
The oval shape diamond has a similar elongated silhouette and shallower depth means it also looks larger on your finger than a heart shape or a round brilliant the same weight. It is much more symmetrical than the heart shape: it’s less dramatic and more quietly refined.
Why We Love Heart Shaped Diamonds
The modern heart shaped diamond is an achievement of the diamond cutter’s art: the perfect symbol of romance. While other fancy shapes go in and out of fashion, the heart remains a classic.
Although it’s sentimental and sweet, it’s often worn by strong willed women, from Queen Elizabeth to Elizabeth Taylor to Lady Gaga to Nikki Minaj, who wears a fancy yellow heart shape engagement ring.

The heart shaped diamond has always been unique, even among fancy shapes. The heart remains the rarest of the ten classic diamond shapes.
And there’s one more thing we love about heart shaped diamonds. Despite how difficult they are to produce, they are about 25 percent less expensive than round brilliant diamonds of the same size and quality.
The most important value factor for a heart-shaped diamond is the symmetry and shape of the outline.
The two halves of the heart should be perfect mirror images. The shape needs to be pleasing, with the lobes and cleft in proportion. All the sides should be gently curved, not flat. The center of the pavilion should be located in a pleasing spot so the radiating pattern of facets seems in balance.
Because heart diamonds are less common than round brilliants, many retailers won’t have any in stock. You are much better off buying fancy shapes like this online because you’ll have a much better selection in your target color, clarity and carat weight so you can assess the shape and cut quality and pick a really beautiful diamond that’s a good value too.
Another factor that you’ll want to consider is the length to width ratio: a comparison of how wide or elongated the heart shape is.
A ratio of 0.8 would be wide and a 1.1 would be taller and skinnier. Which you like best is a matter of personal taste but most people prefer something in the middle.
Many heart shaped diamonds have a darker area in the middle where the facets don't reflect as well. This optical effect is called the “bow-tie” effect because the dark area looks like two triangles corner to corner. Look for a heart shape that is brilliant even in the center area to make sure your heart-shaped diamond is beautiful in different lighting conditions.
