Heart Shaped Diamonds Buying Guide

Heart cut diamond

Heart cut diamonds get their name from the way they are shaped. They resemble stylized hearts and are frequently used in sentimental or figurative jewelry designs.

These exquisite stones are distinguished by their distinctively curved top lobes, known as the “wings," and their rounded bottom point—the "tip" of the heart. A heart-shaped diamond typically has 59 to 62 facets, though the number and their arrangement may vary depending on the cut.

Heart cut diamonds are rare and difficult to cut. To get the best value for your budget when looking for a heart-shaped diamond, it is critical to contemplate certain aspects, such as cut, color, clarity, carat weight, and fluorescence.

We recommend that you heed the following essential factors to get the best and most appealing stone. Here is our list of the best places to buy diamonds.


  • In cut proportions of heart shaped diamonds, the ideal depth is 56 to 62%, the table is 58% to 65%, and the length-to-weight ratio is 0.9-1.1 (also prioritize polish and symmetry). See more below.
  • D-G colors are awesome, but H and I also offer great value. The bigger the carat weight, the more color will show. Prioritize color based on the carat weight.
  • Clarity is important but provides more flexibility (VS2+ clarity grade stones are often eye clean).
  • Avoid fluorescence in heart cut diamonds, but faint is fine and medium blue is suitable for H+ color grades.
  • Buying a heart cut diamond with a GIA or AGS grading report. For lab-grown diamonds, IGI and other labs are fine as well.
  • While prioritizing the 4Cs based on a budget, buying a stone with specs like this if quality is the top priority, this one if quality & size are both important, this one if the size is more important than clarity, and this one if color is an acceptable C to ignore. More here on how to prioritize the 4Cs.

Heart Cut Diamonds: Shape & Symmetry

The complicated cut of the heart shape and symmetry give it its attractiveness. The upper cleft must be delineated, and the two parts of the heart must be identical. Uneven wings, crooked or uneven tip, or a too shallow or deep cleft mean the diamond is poorly cut. Such flaws might detract from the diamond's overall appearance and decrease its worth.

Choosing a heart cut diamond will undoubtedly make jewelry stunning. However, the heart is one of the most complicated diamond shapes to cut, requiring high accuracy to get the optimum shape. An improperly cut diamond will not have a symmetrical and clearly defined heart shape, diminishing its appeal and value.

Admittedly, only some appreciate the heart cut because it has a distinctive form. Therefore, selecting a heart cut diamond that suits your preferences is vital.

Symmetry is still crucial even if you select a non-conventional heart form. A diamond with poor symmetry could not have the proper dimensions to form an aesthetically pleasing jewelry piece.

In conclusion, a heart shaped diamond must be well-cut and symmetrical to look beautiful and valuable. Poor symmetry or an uneven cut can dull a diamond, lower its value, and diminish its overall appeal.

Heart Cut Diamonds: Cut Proportions

A diamond with excellent light refraction will show the most brilliance and fire. The diamond's cut permits light to enter and reflect off its facets, giving them the glitter and brilliance that make them coveted. A poorly cut heart-shaped diamond will reflect light less effectively and give it a lifeless or dreary appearance.

The cut can surprisingly also influence the overall aesthetics of a heart-shaped diamond. A well-cut heart diamond can result in a gorgeous piece of jewelry due to the unique look of the heart. But, if cut poorly by an amateur, the diamond may look asymmetrical or have an undesirable form. Hence, you would be better off consulting a reputable jeweler to ascertain you get the best value.

Compared to other diamond shapes of the same carat weight, heart cut diamonds often appear smaller from the front due to their unique shape. It features a rounded bottom and two lobes at the top, giving it a minimal look, which some people may prefer.

Hence, you might need to select a diamond with a higher carat weight to get your desired size. A well-cut diamond will appear bigger than a badly-cut one, giving it more value for your money.

Cut quality is one of the most important factors that diamond grading laboratories, such as the Gemological Institute of America and the American Gems Society, use to grade diamonds. You can be sure that a certified diamond with a high cut grade will be of the finest quality and that the cut has been scrutinized elaborately by a responsible third party.

Knowing the ideal proportions for a heart cut diamond is paramount before you step into a market to buy one. Use the above chart to get the best heart cut diamond.

Length-to-Width Ratio

The proportion of a diamond's length to width is known as the length-to-width ratio. A heart-shaped diamond should have a length-to-width ratio of between 0.90 and 1.10. Such a proportion will result in a symmetrical and beautiful heart form.

The Depth and Table Percentage

This measures how deep a diamond is in relation to its overall width. A heart-shaped diamond should have a depth percentage between 56% and 61% to have a superb balance of fire and brightness and good light reflection.

Furthermore, the width of the diamond's table (the top facet) to its overall width is measured as the table percentage. A heart-shaped diamond with a table percentage of between 54% and 62% will be ideal for maximum shine.

Girdle Thickness

The girdle is a narrow band and surrounds a diamond at its widest point. A heart-shaped diamond with a medium to a somewhat thick girdle will give it stability and durability to be a lifelong purchase.

Heart Diamonds: Carat Weight & Prices Charts

Heart-shaped diamonds are not as common as some other diamond shapes. A 2 carat heart cut diamond may be more challenging and expensive than a diamond of similar weight but a different shape.

As with all diamonds, a heart cut diamond's price rises with carat weight. You should prepare to pay more if you want a larger heart cut diamond. A two carat heart cut diamond will cost more than twice as much as a one carat diamond since the price per carat rises as the carat weight increases.

The following chart shows our approximate averages prices for heart cut diamonds (prices are for a very good+ cut, no fluorescence, and GIA/AGS graded diamonds):

Color Clarity Price

Heart Cut Diamonds: Color

A color scale from D (colorless) to Z is used to grade diamonds (light yellow or brown). Colorless diamonds lie in the D to F range, while nearly colorless diamonds are in the G to J range. Choosing a colorless or almost colorless diamond will guarantee it has the best beauty and value, even though it could be challenging to tell the difference between diamonds in the D to F range and those in the G to J range.

Diamond color scale

White diamonds with a tint are more common than colorless diamonds. A diamond with a higher color grade in the heart shape will be worth more than one with a lower color grade.

Notably, a diamond's color ultimately comes down to personal preferences. While some people prefer a colorless diamond's cold and white appearance, others favor diamonds with a warmer or yellower tint.

Generally, fluorescence is a negative factor in assessing the quality of a diamond. However, it is particularly important to understand this factor as it relates to the color of a diamond. For insights, read our diamond fluorescence good.

  • Heart Cut Diamonds: Clarity

    The presence or absence of imperfections and flaws on a diamond's exterior and interior are referred to as the stone's clarity. Blemishes are surface flaws, whereas inclusions are internal flaws. These flaws may impact the diamond's look, beauty, and worth, causing the stone to look dull and unattractive.

    When buying a heart cut diamond, clarity is a critical factor to consider. To ensure the finest appearance and best value, select a diamond with high clarity that also has above average color and cut (learn about VVS diamonds). A heart-shaped diamond's glaring flaws or inclusions can reduce its appeal and value.

    Some people love flawless diamonds, while others do not mind minor flaws as long as they do not detract from the stone's overall brilliance. However, buying a diamond with the best clarity grade would be your best bet if you want maximum value for your bucks.

    Certification or Grading Reports

    A grading report and/or certification confirm a diamond's quality and authenticity. It confirms the stone’s features, including its carat weight, cut, color, clarity, and possible treatment. With a certification, you can be sure your purchase is trustworthy and worth your time and money.

    Certification is particularly essential for heart-shaped diamonds, given their unique design and characteristics. You will be allowed to carry out an objective side-by-side comparison between two heart cut diamonds from various sources. If both are certified, you can rest assured that you are comparing diamonds of the same caliber and feature set.

    Certification will also help you determine the quality of your heart cut diamond. You can also find a good resale value easily since it has been certified by a respectable third party.

    Without certification, it can be extremely challenging to know whether the diamond you want is genuine or altered in any way. A certified diamond guarantees that you make a genuine, high-quality diamond purchase and guards against fraud or buying a fake heart cut stone.

    Final Thoughts

    Heart cut diamonds are unique and rare. While they are less popular than round or oval cut diamonds, they still attract many buyers. If you choose this shape, get the cut proportions right and buy a stone with the right color, clarity, and certification.
