Heart Shaped Diamonds: Your In-Depth Guide - Do Amore

Heart Shaped Diamonds

Heart shaped diamonds are romantic and whimsical. As the universal symbol of love, choosing a Heart cut is the ultimate in romance. However, at the time of writing, only 1.6% of GIA-certified diamonds available for sale globally are Hearts (19,195 out of 1,178,007 diamonds)! In fact, they are the second most uncommon diamond shape in the world. Because of this rarity, most jewelers do not have much experience with Heart shaped diamonds. So, let’s go over several things you should look for prior to selecting one.

Table, Depth & Other Specifications for Ideal Heart Shaped Diamonds

Heart cut diamonds are dreamy and whimsical. They have soft curving arcs (or “lobes”) at the top, and a graceful point at the bottom. Hearts can be tall and slender, or shorter and plump. Couples choosing a Heart should always look for a symmetrical, pleasing shape, a centered culet, and lack of bowtie.

Like other fancy cuts, GIA does not grade the cut quality of Heart shaped diamonds. So, jewelers that advertise Hearts with cut grades are merely offering their own opinion. The GIA Certificate will not have a cut grade. Couples should also know there is no industry accepted standard of what makes an “Ideal Cut Heart Shaped Diamond.” That said, there are certain things look for to ensure your Heart is the graceful beauty you want. We have put together the table below as a guideline for evaluating Heart cut.

Color Recommendations for Heart Shaped Diamonds

A diamond’s “color” is how white it is, or how much yellow or
brown warmth it shows. Evaluating color in Heart diamonds is unique!
Color can concentrate in the bottom point of your stone due to different
faceting technique, so always look at each area of your gem. You want your
stone to look the same color in all areas.

Luckily, the brilliance of a Heart will mask a bit of color, so G-H colored diamonds will often appear colorless. D-F color Heart shapes will command a higher price. The color chart below provides some guidance for evaluating diamond color:

Clarity Recommendations for Heart Shaped Diamonds

A diamond’s “clarity” is how many, or how few, birthmarks (“inclusions”) it has. Almost all diamonds have birthmarks – just like us!

Heart cut diamonds are “brilliant” cut stones that produce a ton of sparkle. As a result, small inclusions can be hidden by well-placed facets. So, couples choosing a Heart cut diamond can often select VS2 or SI1 clarity gems and still get a flawless, eye-clean look. Because clarity is graded by how obvious inclusions are, a larger diamond with a small inclusion will receive a better clarity grade than a smaller stone with the same size inclusion. That said, this also means larger stones may have small eye-visible inclusions that are not too distracting. So, always look over your stone carefully (we double check for “eye clean” clarity in every stone we sell and inform couples if they are not!). The clarity chart below will provide some guidance.

All diamonds in our diamond search engine have the length and width listed. This ratio (length divided by width) helps couples choose the overall shape of their Heart. Most people prefer their Heart to have a ratio between 1.10 and 1.20. A skinnier Heart will be closer to 1.10, a plumper Heart is closer to 1.20. Our gemologist is partial to a nice plump heart – it gives a bigger bang for the buck!

Money Tips

When looking for a Heart, the overall shape of your diamond is the most important part. Great shape and sparkle will give you the best bang for your buck. Don’t be fooled by an unsymmetrical, pointy-lobed Heart for a low price! Instead, look for a nice plump Heart shaped diamond. It will give you the biggest look for the money, and the most sparkle!

3 Things to Ask Your Jeweler

    Photo & Video

    Always ask the jeweler you are buying from for a detailed picture or video like these stones. Look for soft, curving lobes and symmetrical shape.

    Inspect It

    Ask the jeweler to actually see the diamond. Inspect the diamond for visible inclusions and color consistency!

  • 03.

    Measure It

    Make sure your diamond’s length-to-width falls between 1.10 and 1.20. Closer to 1.20 will give you a bigger bang for your buck!
