The heart diamond is a fancy cut and contains almost 60 facets that capture and reflect light, resulting in a visible brilliance. The wings of the heart are symmetrical, with a graceful curve that provides excellent fire.

Hearts are one of the most popular fancy cuts and that tradition hasn’t changed in over 600 years. In the 15th century, heart cut diamonds were gifted by royalty as a sign of friendship. Mary Queen of Scots once sent a heart-shaped diamond ring to Queen Elizabeth.

Your cut should have at least 59 facets and a ratio between 0.90 and 1.10. This will make your heart as tall as it is wide, for the perfect heart proportions. Heart cut diamonds look their best when they’re above 0.50 carats – anything below will make it hard to identify its recognisable shape, especially once the stone is set. The heart’s cleft should be even and distinct.

This regal cut requires a great deal of skill and precision to create. Because of this, it has become a prized stone, one that remains a popular gift for lovers.
