Heart Engagement Rings: The Complete Guide
A heart shaped diamond ring is the sentimentalist's pick, the one cut that doesn't need explaining. This guide covers why buyers choose it, what makes it harder to cut well, whether it can look tacky, and which of our 4 styles fit different budgets, plus every question we get asked before someone buys one.
Heart: The Sentimentalist
Choose this cut if the personality behind the proposal is unapologetically romantic and wants the ring itself to say what words might not quite capture. Its symbolism is built right into the silhouette, two symmetrical lobes meeting at a point, no subtlety required.
Why this cut demands more precision
This silhouette is one of the hardest cuts to get right, since any asymmetry between the two lobes is immediately visible at a glance, unlike a round or oval stone where small imperfections are easier to hide within the overall shape. The Gemological Institute of America (GIA) lists this among the most demanding fancy shapes to cut well for exactly this reason. That's part of why it's rarer than the shapes around it, and why cut quality matters more here than almost anywhere else.
What to look for when buying
Check the outline from directly above: the two lobes should be genuinely even in size and curve, the cleft between them should form a distinct, symmetrical notch rather than a shallow dip, and the point at the bottom should be neither too blunt nor drawn out to a fragile sliver. A stone photographed or viewed at an angle can hide minor unevenness, so ask to see it face-up under good light before buying, or view close-up photography from directly above if you're buying online.
Does a heart shaped diamond look tacky
Not when it's well cut and well set. The concern usually comes from picturing an exaggerated, overly literal outline, but a well proportioned stone reads as elegant and symmetrical rather than novelty. A clean, simple setting, prong or halo, keeps the focus on the diamond's proportions rather than making the shape feel cartoonish.
How much does this shape cost
It typically costs more per carat than round, since achieving symmetrical lobes and a clean point wastes more of the rough stone and demands more cutting skill. Setting style still moves the price: a plain prong solitaire is the most affordable way to wear it, while a halo adds cost through extra stones and labour.
How it compares to other shapes
Compared with round, this cut is rarer, costs more per carat, and reads as overtly symbolic rather than classic. Compared with pear, it has two lobes and a top notch rather than a single smooth curve, making it the more literal romantic statement of the two. For the full side by side breakdown across all eight cuts we carry, see our Engagement Ring Shape Guide.
Who this shape suits best
It suits someone unapologetically sentimental, who wants their ring to read as romantic at a glance rather than one that plays it safe. If a shape with wider jeweller support and less cutting risk matters more to you, a round cut from our Round Engagement Rings guide may suit better.
What carat weight looks like on the hand
A 1 carat stone in this cut typically measures around 6.5mm by 6.5mm, similar in overall footprint to a round stone of the same weight, though the lobes and point give it a visually larger presence than the raw measurements suggest.

Choosing the right setting for you
A four-prong setting, with one prong positioned at the top notch and one at the point, is the classic way to protect both vulnerable spots. A halo setting adds surrounding diamonds for extra brilliance while also giving the outline a small amount of additional definition.
Every stone in this collection is a genuine lab grown diamond, chemically and optically identical to a mined one. Your choice of cut doesn't change that, it only changes the silhouette and how the light returns.
Caring for your ring after you buy it
Both the top notch and the bottom point are worth checking regularly, since they're the most exposed parts of the stone on any setting. For the full routine, see our guide on how to care for your engagement ring.
Frequently asked questions
What is a heart shaped diamond? It's a brilliant cut diamond shaped like a heart, with two symmetrical rounded lobes meeting at a single point. It's one of the more difficult shapes to cut well, since any asymmetry is immediately visible.
Are heart shaped diamonds tacky? Not when they're well proportioned and simply set. A clean, symmetrical cut in a classic prong or halo setting reads as elegant rather than novelty.
Is a heart shaped diamond more expensive than round? Generally yes, per carat, since achieving clean, symmetrical lobes wastes more of the rough diamond and requires more cutting skill than a round brilliant.
How do you tell if a heart shaped diamond is well cut? Look for even, matching lobes on both sides, a clean, well defined cleft at the top, and a point that isn't too sharp or too rounded. Genuine asymmetry is visible to the naked eye on this cut.
Why is a heart shaped diamond rare? The cutting process demands more precision than most other shapes, since any unevenness between the two lobes is obvious, which means fewer rough diamonds are suitable and fewer cutters take it on.
Can I get this cut in rose or white gold? Yes, every setting in this collection is available in Lucira's 14K gold options, so your choice of cut doesn't limit which metal tone you choose.
