Learn everything about heart cut diamonds, including sparkle, proportions, pricing, settings, pros and cons, and expert advice on choosing the perfect stone
While less common than other diamond shapes, the heart cut remains a timeless choice for buyers seeking something expressive, meaningful, and visually unique. Its appearance requires precise cutting and symmetry to achieve a well-defined shape and balanced sparkle.
In this guide, we’ll explain everything you need to know about heart cut diamonds, including their history, proportions, sparkle, pricing, advantages, disadvantages, and how to choose the best heart cut loose diamond.
What Is a Heart Cut Diamond?
A heart cut diamond is a brilliant-cut diamond shaped like a heart, featuring a cleft at the top and a pointed tip at the bottom.
Typically based on the brilliant cutting style, heart diamonds are designed to deliver strong sparkle and fire while maintaining a clearly defined romantic silhouette.
Key characteristics include:
- Heart-shaped outline
- Brilliant-cut faceting
- Strong sparkle and fire
- Distinct cleft at the top
- Pointed base for symmetry
Because of its complex shape, symmetry plays a crucial role in how well a heart cut diamond appears.
How To Choose a Heart Cut
Check Symmetry First
Both halves of the heart should be perfectly even. Uneven lobes are one of the most noticeable flaws in poorly cut heart diamonds.
Assess the Shape Definition
A well-cut heart should have a clear cleft at the top and a clean, sharp point at the base without appearing too blunt or too narrow.
Consider Length-to-Width Ratio
This ratio affects whether the heart appears wider and fuller or longer and more elegant.
Choose a Visible Shape
The outline is just as important as brilliance, so shape definition should never be compromised.
Which Heart Cut Is Best?
There is no single “best” heart cut diamond — the ideal choice depends on personal preference.
- Choose a balanced heart for symmetrical proportions and classic appearance.
- Choose a slightly elongated heart for a more elegant silhouette.
- Choose strong symmetry for the most defined shape.
- Choose excellent brilliance for maximum sparkle.
- Choose a well-defined cleft and point for the cleanest outline.

Heart Cut vs Oval Cut
Heart and oval cut diamonds both use brilliant faceting but offer very different aesthetics.

Heart diamonds are highly symbolic and feature a defined cleft and point, making them more expressive and distinctive.
Oval cuts prioritise elegance and versatility, while heart cuts prioritise symbolism and visual impact.

Are Heart Cuts Good Value?
Heart cut diamonds can offer strong value, but they require careful selection.
Because they demand precise cutting and symmetry, well-cut heart diamonds are less common and can sometimes carry a premium. However, they often appear larger face-up than round diamonds of the same carat weight.
For buyers seeking a highly symbolic and distinctive diamond shape, the heart cut offers excellent emotional and visual value.
History of the Heart Cut Diamond
The heart shape has been used in jewellery for centuries as a symbol of love and romance. While early versions were more primitive, modern heart cut diamonds evolved with advances in brilliant-cut technology.
By the 20th century, improved diamond cutting techniques allowed for more symmetrical and precise heart shapes, making them suitable for fine jewellery.
Today, the heart cut remains a niche but meaningful choice for buyers seeking a deeply symbolic diamond shape.
