Frequently Asked Questions
What is the most important factor when choosing a heart shape diamond? +
Symmetry is the most critical factor. The two halves of the heart must be identical mirrors of each other. If the 'lobes' are uneven or the 'point' is off-center, the diamond will look lopsided or distorted once set in a ring.
Do heart shape diamonds have a bow-tie effect? +
Yes. Much like ovals and marquise cuts, heart diamonds can exhibit a 'bow-tie'—a dark shadow across the center. A well-cut heart will minimize this shadow, ensuring light reflects evenly across the entire surface of the stone.
What size should a heart shape diamond be to look its best? +
Heart shapes are generally not recommended for diamonds under 0.50 carats. Because the shape is so complex, the distinct 'cleft' and 'point' become difficult to see in smaller stones, often making them look like simple round or pear shapes from a distance.
What is the ideal length-to-width ratio for a heart diamond? +
The classic, 'perfect' heart ratio is 1.00 (exactly as wide as it is long). Some prefer a slightly more elongated look (1.05 to 1.10), but going too far in either direction can make the heart look either 'too fat' or 'stretched.'
Which setting is best for a heart shape engagement ring? +
A five-prong setting is the standard choice. This includes two prongs for the lobes, two for the sides, and a V-prong to protect the sharp bottom point, which is the most vulnerable part of the diamond.
Are heart shape diamonds more expensive than round diamonds? +
No. Heart shape diamonds typically cost about 15% to 25% less than round brilliant diamonds of the same carat weight. However, because they require a highly skilled cutter and involve more waste of the rough stone, they can be rarer to find in high quality.
How should the 'cleft' of the heart look? +
The cleft (the inward dip at the top) should be sharp and distinct. If the cleft is too shallow, the diamond may look like a pear shape; if it is too deep, it can create structural integrity issues or collect dirt easily.
