Heart-shaped lab-grown diamonds: the short answer
A heart diamond is a modified brilliant cut whose quality depends heavily on symmetry. Look for two even lobes, a clear central cleft, a centered point and brightness that carries across the stone. The outline becomes easier to read at larger sizes, especially once it is set.
Choose the shape with your eyes before paying for higher color or clarity. Heart cuts vary from broad and rounded to long and narrow, and neither style is automatically better.
We compare heart diamonds using their face-up videos, measurements, grading reports and prices. We also look at how the setting frames the cleft and protects the point, because a well-proportioned loose heart can lose its outline behind heavy or uneven prongs.
What one-carat heart-shaped diamonds cost
We checked Ritani's one-carat inventory on September 11, 2026. A 1.00-carat D-color, VS1 heart with an IGI report cost $396 and measured 6.77 × 6.19 mm. The table places that diamond beside lower-priced hearts and rounds with matching E color and VVS2 clarity.
| September 2026 comparison | Price |
|---|---|
| Typical price among five lower-priced 1-carat E/VVS2 hearts | $297 |
| Highlighted 1.00-carat D/VS1 heart | $396 |
| Typical price among five lower-priced 1-carat E/VVS2 rounds | $240 |

What makes a good heart-shaped diamond?
The lobes should match in height and fullness. The cleft should be distinct without cutting too deeply into the center, and the point should sit on the same axis. A weak outline can look like a rounded pear once prongs cover part of the stone.
Heart shapes have appeared in jewelry for centuries and are closely tied to romantic and commemorative pieces. That symbolism is an advantage if you want a diamond that immediately communicates affection, but it also makes the outline more important than it would be in many abstract shapes. A heart that is poorly proportioned will not become convincing simply because its color and clarity grades are high.
A brief history of the heart-shaped diamond
Heart motifs existed long before modern brilliant cutting. Early heart-like diamonds were difficult to make symmetrical because cutters worked by hand and had to preserve valuable rough. Royal and aristocratic gifts helped connect the shape with affection, loyalty and diplomacy.
Modern equipment gives cutters much better control, but the basic challenge remains: creating two balanced lobes, a readable cleft and a centered point while preserving brightness. Lab-grown rough changes the economics rather than the design standard. It makes larger heart diamonds accessible to more buyers, but it does not make every finished heart equally attractive.
Heart diamonds have also appeared in several well-known pieces of jewelry. Mary, Queen of Scots sent a heart-shaped diamond ring to Elizabeth I in the 16th century, while more recent celebrity rings helped keep the shape visible as an alternative to round and oval centers. Those examples explain some of the romance around the cut, but they are not a buying standard: a smaller heart with stronger symmetry will usually look better than a larger one with uneven lobes.
Heart cut compared with pear, oval and round
A heart and pear are both modified brilliant cuts with a pointed end. The heart adds a cleft and two lobes, which makes symmetry harder to execute and normally leaves fewer stones to choose from. A pear looks more fluid and elongated; a heart looks more symbolic and compact.
An oval offers an elongated outline without a vulnerable point, while a round brilliant is easier to compare using established cut grades and proportions. Hearts are the least standardized of the group. Choose one because you love its outline, not because a table suggests it should perform like a round.
How a heart shape is cut
A heart is a modified brilliant cut related to the pear. The cutter has to form two matching lobes and a clean cleft while keeping enough weight, brightness and width. That trade-off explains why two hearts with the same carat weight and grades can look very different. There is no GIA overall cut grade for heart shapes, so the face-up video, symmetry, measurements, polish and setting matter more than a single label.

What lab-grown origin changes—and what it does not
A lab-grown heart and a mined heart have the same crystal structure, hardness and optical properties. Both are cut and polished after the rough forms, and both can receive independent grading reports. Neither origin solves poor symmetry, weak transparency or an unattractive outline.
The differences are price and origin. Lab-grown hearts generally cost far less, allowing you to compare larger sizes or higher grades without the rarity premium attached to mined diamonds. They also avoid excavation and mining infrastructure. Electricity use varies between growers, so renewable or lower-carbon production provides the strongest environmental case.
How is a heart-shaped lab diamond made?
The diamond grows first; a cutter then shapes and polishes it into a heart. The two main growth methods are high pressure, high temperature (HPHT), which uses heat and pressure, and chemical vapor deposition (CVD), which builds diamond on a seed using carbon-containing gas. GIA explains both growth methods. Neither method creates the finished heart outline inside the growth chamber.
How to choose a heart-shaped lab diamond
Compare symmetry and outline
View the diamond face-up and trace both sides visually. The lobes should be balanced and the point centered. Ratios near 0.90–1.10 cover many pleasing hearts: lower ratios look wider, while higher ratios look longer.
Do not judge symmetry from the grading-report word alone. Laboratory symmetry grades describe facet alignment and finish, but the visible outline can still have uneven lobes or shoulders. Pause the seller's video face-up and compare the left and right sides. Then watch the diamond turn to see whether both halves brighten in a similar way.
The cleft can be shallow and subtle or deep and dramatic. A shallow cleft may disappear under prongs; a very deep one can create a narrow waist and trap darkness. Neither is automatically wrong, but the finished setting should preserve the outline you chose.
Choose enough visible size
Small heart diamonds can be attractive in earrings or a cluster, but for a solitaire center stone the shape usually reads more clearly around one carat and above. Compare millimeter width and length—not carat alone.
Carat measures weight, including material hidden below the girdle. A deep heart can weigh the same as a broader one while looking smaller from above. Compare the dimensions with several diamonds of the same weight, and check that a very thin girdle does not create unnecessary vulnerability near the point or cleft.
Inspect sparkle, color and clarity
Watch the video for even brightness, especially below the cleft and through the center. F–H color and VS1–VS2 clarity are useful starting points. Check inclusions near the cleft and point, then decide whether a higher grade produces a visible benefit.
Heart shapes do not receive a universally comparable overall cut grade from GIA. Use table and depth as screening information, not a pass/fail formula. A table around the mid-50s to mid-60s and depth around the high-50s to upper-60s can produce candidates, but the outline and moving image are more important.
Color can be more visible near the point and thicker areas. In white gold or platinum, G–H is a practical value range for many sizes; yellow or rose gold can work well with more warmth. Larger hearts reveal color more easily, so compare the actual stone against a neutral background.
Heart shapes also work beautifully with intentional color, such as pink. For a fancy-colored diamond, compare the hue and how evenly it appears across the face, rather than using the D–Z scale intended for colorless-to-light-yellow diamonds.

For clarity, look beyond whether a diamond is technically eye-clean. An inclusion near the point or cleft deserves attention because those are structurally sensitive areas. Diffuse clouds or growth features that reduce transparency can matter more than a small inclusion near an edge. A clean VS2 may outperform a higher-graded stone with weaker transparency.
Review the grading report and video together
Confirm that the report identifies the diamond as laboratory-grown and compare the report number, dimensions, polish, symmetry, fluorescence and clarity details with the listing. The report documents the diamond; it does not tell you whether the lobes look balanced or the cleft is attractive.
Use videos filmed against a consistent background. Rotate between face-up and angled views, and avoid selecting from a highly magnified still image alone. Hearts benefit more than most shapes from comparing several candidates side by side.
The example lists 10.57 × 11.85 × 6.49 mm and shows where inclusions were plotted. Notice that the Excellent polish and symmetry results are separate from the shape: they do not replace your own comparison of the lobes, cleft and brightness in the video.
Heart-shaped engagement rings
A three-prong setting can protect the point while leaving the lobes open; a bezel gives more complete protection. Halos make the outline more obvious, while a plain solitaire keeps the design modern. Check that the prongs do not make one lobe look larger than the other.
A five-prong setting can secure the point and frame both lobes, while a V-prong gives the tip more metal coverage. If the ring will be worn every day, ask how high the heart sits and whether the point or cleft can catch on clothing. A low basket or bezel is often the more practical choice for an active wearer.
The usual orientation places the point toward the fingertip, visually lengthening the hand. Turning the heart toward the wearer changes the symbolism and can feel more personal. This is entirely a design preference.
Heart centers also work with colored side stones, split-shank bands and double halos, but the surrounding design should not blur the cleft. If you are buying online, ask for a face-up image of the finished ring or use a realistic configurator. The loose diamond can have a clear heart outline that becomes less distinct once large prongs or a heavy halo surround it.

Heart-shaped pendants and other jewelry
Heart cuts are a natural choice for pendants because the design hangs upright and reads clearly. Smaller matched stones also work in studs, drops and bracelets.
Pendants protect the point from many of the impacts a ring receives, making them suitable for delicate three-prong designs. For earrings, compare the pair face-up: differences in lobe fullness or ratio are more obvious when two hearts sit beside one another. Bracelets need secure, low settings because the stones regularly contact desks and other surfaces.

See at Brilliant EarthHow much does a heart-shaped lab diamond cost?
Prices depend on size, symmetry, face-up dimensions, color, clarity, grading report and seller. Among five of Ritani's lower-priced matching diamonds in September 2026, a typical one-carat E/VVS2 heart cost $297, compared with $240 for a round. The D/VS1 heart highlighted above was $396. Heart pricing moves with inventory, so compare the actual outline and video before choosing the cheapest stone.
The larger saving is against mined diamonds. Across diamond jewelry more broadly, BriteCo's 2026 appraisal data reported $2,057 per carat for lab-grown engagement-ring diamonds versus $8,428 for mined diamonds in 2025—a difference of about 76%. A particular heart may differ, but lab growth usually makes a larger, clearer shape far more accessible.
Lab-grown diamonds avoid the mine itself and its associated land, water and community impacts. Production uses significant electricity, so the environmental advantage is strongest when that energy comes from renewable or low-carbon sources.
How to save without compromising the shape
- Compare dimensions around popular carat thresholds. A 0.95-carat heart may look almost the same as a deeper 1.00-carat stone.
- Pay for an eye-clean diamond rather than the highest clarity grade. VS2 can be excellent when inclusions are well placed.
- Compare G–H color with more expensive colorless grades in the intended setting metal.
- Search more than one seller because heart inventories are relatively small and uneven.
- Put symmetry, brightness and outline ahead of a low headline price.
Sales can reduce a setting or finished-jewelry price, but loose-diamond exclusions are common. Compare the complete ring total and promotion terms rather than assuming an advertised percentage applies to the center stone.
Caring for a heart-shaped diamond
Clean it like any other diamond: soak the jewelry in warm water with mild dish soap, brush gently with a soft toothbrush, rinse safely and dry with a lint-free cloth. The shape does not require a special chemical cleaner.
The point and cleft do require attention. Check that the protective prong remains aligned and that fibers do not repeatedly catch around the cleft. Stop wearing the piece if the diamond moves or a prong lifts. For a frequently worn ring, periodic professional inspection can identify wear before the stone becomes loose.
Store heart-shaped jewelry separately so its point does not scratch other pieces and other diamonds do not contact it. Remove a heart ring for sports, lifting, gardening and household work likely to strike or bend the setting.
When traveling, use a padded jewelry case or wrap the piece in a soft cloth so it cannot move against other jewelry. Keep chains apart to prevent tangles around the setting.
Where to buy heart-shaped lab-grown diamonds
Look for a seller that shows the actual diamond in motion and provides its grading report. Then compare the complete ring price, setting choice, service and return terms.
Start with Ritani for loose-diamond selection and pricing. Brilliant Earth, With Clarity and Grown Brilliance are useful for comparing finished designs.
Because heart inventory is smaller, search broadly before compromising on symmetry. Save the report numbers and dimensions of promising stones, compare the complete ring price, and ask a gemologist to comment on any dark center or uneven outline visible in the video. A seller with fewer hearts may still have the best individual stone.

Heart-shaped FAQ
What size makes a heart shape easy to see?
Around one carat and above is a useful starting point for a solitaire, although outline, dimensions and setting all affect how clearly it reads.
Are heart-shaped diamonds more expensive than round diamonds?
Not always. In our September 2026 comparison, the typical price among five lower-priced one-carat E/VVS2 hearts was $297, versus $240 for rounds with those grades. That sample favored rounds, but shape prices depend on the diamonds available and the seller. Compare the actual specifications and face-up appearance, not an assumed premium for the heart shape.
Are heart-shaped diamonds out of style?
No. A heart is a distinctive, romantic choice rather than a style everyone will want. Choose it for someone who likes the shape; a simple solitaire, a halo or a small pendant can each give it a different feel.
Which way should a heart ring point?
Traditionally the point faces toward the fingertip, but either direction works. Choose the orientation the wearer prefers.
Are heart-shaped diamonds more fragile?
The diamond is as hard as other diamond shapes, but the exposed point and cleft need protection. Choose a secure prong or bezel design and remove the ring for activities likely to cause an impact.
Is a heart-shaped lab diamond different from a mined heart?
The cutting and buying criteria are the same. Both are diamonds and both can have excellent or poor symmetry. The meaningful differences are origin, price and the environmental and social considerations attached to production or mining.
