About Heart Cut Lab Grown Diamonds
Heart cut lab grown diamonds are the most romantic and emotionally meaningful diamond shape in the world — a brilliant cut diamond crafted into a perfect heart silhouette that speaks a language no other diamond shape can. Bold, distinctive, and deeply personal, the heart cut is the ultimate expression of love, devotion, and individuality. At Variation, our certified collection brings you hundreds of ethically created heart cut lab grown diamonds at prices that simply cannot be matched by mined stones.
What Is a Heart Cut Diamond?
The heart cut diamond is a modified brilliant cut featuring 56 to 58 facets precisely arranged to maximize light reflection and brilliance across its distinctive heart-shaped silhouette. One of the most technically demanding diamond cuts to produce, the heart cut requires exceptional skill and precision — the two lobes at the top must be perfectly symmetrical, the cleft must be sharp and well-defined, and the pointed bottom must be precise and centered.
First documented in the 16th century when Mary Queen of Scots sent a heart shaped diamond ring to Queen Elizabeth I as a symbol of friendship and goodwill, the heart cut has been the universal symbol of romantic love and devotion for centuries — making it the most emotionally powerful diamond shape available.

How to Choose the Right Heart Cut Lab Grown Diamond
1. Symmetry Is Everything
Symmetry is the single most critical factor for a heart cut diamond. The two lobes must be perfectly equal in size and shape — any asymmetry is immediately visible and significantly detracts from the stone's beauty and romantic appeal. Always choose Excellent symmetry grades and view the stone face-up before purchasing.
2. Choose the Right Length-to-Width Ratio
A length-to-width ratio of 0.95–1.05 produces the most classic, balanced heart shape. Below 0.95 produces a slimmer, more elongated heart; above 1.05 produces a wider, fuller heart. For the most universally recognized and flattering heart shape, stay as close to 1.00 as possible.
3. Check the Cleft Definition
The cleft — the V-shaped indentation at the top center of the heart — is a defining feature of the heart cut. It should be sharp, well-defined, and perfectly centered. A shallow or poorly defined cleft makes the heart shape difficult to recognize, especially in smaller carat weights. Always view the stone face-up to assess cleft definition before purchasing.
4. Color Recommendations
Heart cut diamonds retain color slightly more than round diamonds. For white gold or platinum settings, choose D–F color grades for a pure, brilliant appearance. For yellow or rose gold settings — which are particularly popular for heart cut diamonds given their romantic warmth — G–H color grades pair beautifully and offer excellent value.
5. Clarity Sweet Spot
VS1–VS2 clarity is the sweet spot for heart cut diamonds — eye-clean to the naked eye while offering significant savings over Flawless grades. Pay particular attention to inclusions near the pointed bottom tip, as this area is more vulnerable to chipping and inclusions are more visible at the point.
6. Choose 0.50ct or Larger
The heart shape is most recognizable and visually impactful in stones of 0.50ct or larger. In very small carat weights the heart silhouette can be difficult to distinguish without magnification. For maximum romantic impact, choose a stone of at least 0.70ct or larger.

Frequently Asked Questions
Are heart cut lab grown diamonds real diamonds?
Yes. Lab grown diamonds are 100% real diamonds. They share the same physical, chemical, and optical properties as mined diamonds and are certified by the same internationally recognized grading laboratories.
What carat size is best for a heart cut diamond?
A minimum of 0.50ct is recommended for a heart cut diamond — the heart silhouette is most recognizable and visually impactful at this size and above. For maximum romantic impact and a clearly visible heart shape, 0.70ct or larger is ideal.
Why is symmetry so important for a heart cut diamond?
The heart cut's beauty and romantic appeal depend entirely on the perfect symmetry of its two lobes. Unequal lobes create an immediately visible imbalance that detracts from the stone's appearance and meaning. Always prioritize Excellent symmetry when selecting a heart cut diamond.
What is the best setting for a heart cut diamond?
A three-prong setting — with two prongs on the lobes and one on the point — is the most popular and practical setting for a heart cut diamond. It secures the stone at its most vulnerable points while keeping the distinctive silhouette fully visible. A bezel or halo setting also works beautifully and offers additional protection for the pointed tip.
What is the difference between a heart cut and a pear cut diamond?
Both are distinctive brilliant cut diamonds with a pointed bottom but they differ entirely in shape and meaning. A pear cut has one rounded end tapering to a single point — like a teardrop. A heart cut has two rounded lobes at the top with a defined cleft and a single pointed bottom — creating the universally recognized heart silhouette. The heart cut is the more emotionally expressive of the two shapes.
Are lab grown heart cut diamonds cheaper than mined ones?
Yes — priced up to 80% less than an equivalent mined diamond, with no difference in beauty, durability, or certification.
