Heart Shaped Diamonds: The Complete Guide to Buying the Perfect Symbol of Love

Among all diamond shapes, none conveys emotion as directly as the heart shaped diamond. This distinctive cut combines romantic symbolism with technical brilliance, making it a popular choice for heart shaped engagement rings, anniversary gifts, and personal statement pieces. However, buying heart shaped diamonds requires understanding their unique characteristics, quality factors, and setting requirements that differ significantly from traditional cuts.

This guide explains what is a heart shaped diamond, how to evaluate heart cut diamond quality, what affects heart shaped diamond price, and how to select the best heart shaped diamond for your needs. You'll learn about heart diamond carat size recommendations, protective heart shaped diamond settings, and the heart shaped diamond pros and cons to make an informed decision.

 

What Is a Heart Shaped Diamond?

A heart shaped diamond is a modified brilliant cut featuring 56–58 facets arranged in a distinctive heart outline. The shape consists of three key elements:

• Two rounded lobes (the upper curves)

• A cleft (the indentation between lobes at the top)

• A pointed apex (the sharp bottom tip)

Technically, the heart cut starts as a pear shape with an additional cleft cut into the rounded end. This requires exceptional cutting skill and larger rough diamonds, making hearts represent approximately 1% of all polished diamonds.

Historical significance: Heart diamonds gained prominence in 1463 when the Duke of Milan referenced them in correspondence. Later, Mary Queen of Scots gifted Queen Elizabeth I a heart-shaped diamond ring as a symbol of friendship. The shape surged in popularity during the 1980s–1990s and continues to appeal to buyers seeking unique, romantic symbolism.

Key proportions: The ideal length-to-width ratio is 1:1 for perfect symmetry, though 0.95–1.05 is acceptable. Symmetry is critical—uneven lobes or an off-center cleft create a lopsided appearance and reduce value.

 

 

How to Choose a High-Quality Heart Shaped Diamond

When evaluating heart cut diamond quality, prioritize cut and symmetry over colour and clarity—a reverse of typical diamond-buying wisdom.

Critical Quality Factors:

1. Symmetry (Most Important):

• Both lobes must be identical in size and shape

• The cleft should be well-defined and centered

• The point must align with the center of the cleft

• Only consider Excellent or Very Good symmetry grades

2. Cut Proportions:

• Depth: 58–63%

• Table: 53–63%

• Length-to-Width Ratio: 0.95–1.05

Poor proportions create a bow-tie effect (dark shadow across the center) or dull appearance.

3. Colour Grade:

• For white gold/platinum settings: G–H colour minimum

• For yellow/rose gold settings: I–J colour acceptable

• Colour concentrates in the point and cleft areas, making it more visible than in round diamonds

4. Clarity Grade:

• Recommended: VS2–SI1 (sweet spot for value)

• The brilliant faceting hides inclusions effectively

• Avoid: Inclusions near the point (structural weakness) or in the cleft (highly visible)

5. Expert Tip:
Always view heart shaped diamonds from multiple angles. Some stones look perfect from above but show asymmetry or bow-ties from the side.

 

 

Heart Shaped Diamond Carat Size Guide

Minimum recommended size: 0.50 carats. Below this, the heart shape becomes difficult to recognize and may appear round or pear-shaped.

Ideal sizes for engagement rings:

Key insight: Heart diamond carat size matters more than in other shapes because the cleft, lobes, and point need sufficient surface area to be clearly defined. Hearts also face up larger than round diamonds of the same carat weight due to their shallow cut.

Finger size considerations:

• Smaller fingers (size 4–6): 0.75–1.25 carats

• Average fingers (size 6–7): 1.00–1.50 carats

• Larger fingers (size 7+): 1.50–2.00+ carats

 

 

Best Settings for Heart Shaped Diamonds

Protective settings are essential for heart shaped diamond settings due to the vulnerable point.

Recommended Settings:

1. Prong Settings:

• 5-prong or 6-prong: Prongs at the cleft (2), sides (2), and point (1–2)

• V-prong at the point: Essential for protecting the sharp tip

• Avoid 4-prong settings: Inadequate protection for the point

2. Bezel Settings:

• Full or partial bezel wraps the diamond's edge in metal

• Maximum protection for the point

• Creates a modern, sleek aesthetic

3. Halo Settings:

• Surrounding smaller diamonds enhance the heart shape definition

• Makes the center stone appear larger

• Provides additional protection

4. Three-Stone Settings:

• Side stones (baguettes, rounds, or smaller hearts) frame the center heart

• Adds brilliance and visual interest

• Distributes attention across the ring

Metal Recommendations:

• Platinum: Most durable; hypoallergenic; maintains shine without plating

• White Gold: Popular and affordable; requires periodic rhodium plating

• Yellow Gold: Vintage appeal; masks warmer colour grades (I–J)

• Rose Gold: Romantic aesthetic; trendy; complements most skin tones
