What Are Heart Cut Diamonds?
A heart-cut diamond is a brilliant-cut stone shaped exactly like a heart — a universal symbol of love. It’s one of the most technically demanding diamond shapes to craft, requiring exceptional precision to ensure perfect symmetry between the lobes and the point.
The heart cut is part of the modified brilliant family, just like the oval, pear, and marquise cuts, meaning it offers exceptional sparkle and fire. With typically 56–58 facets, a heart-cut diamond is designed to reflect light beautifully from every angle.
This shape is a favourite among romantics and celebrities alike — from Lady Gaga’s heart-shaped engagement ring to the timeless pieces seen in royal collections.
How Are Heart Cut Diamonds Made?
Creating a heart-cut diamond requires not only technical skill but also artistic craftsmanship. Every curve and point must be perfectly balanced for the diamond to sparkle beautifully.
Here’s how it’s made:
-
Selecting the rough diamond – A high-quality, symmetrical rough diamond with few inclusions is chosen.
-
Planning the cut – Diamond cutters use advanced 3D mapping technology to align the shape perfectly.
-
Pre-forming – The cutter shapes a rounded diamond (similar to a pear) before sculpting the cleft (the top indentation).
-
Polishing and faceting – Each facet is carefully placed to maximise brilliance and maintain symmetry.
A small difference in angle can make the heart look uneven, so only master gem cutters can achieve the perfect shape.
Fun fact: A heart-cut diamond must be at least 0.5 carats to display its heart shape clearly — anything smaller often loses definition.
Who Created Heart Diamonds and Why?
The heart-cut diamond has one of the richest histories in gemology. Its origins date back to the 16th century, when it was considered a symbol of royalty and eternal love.
One of the earliest mentions of heart-shaped diamonds came in 1562, when Mary, Queen of Scots, sent one to Queen Elizabeth I as a symbol of friendship and goodwill.
The modern heart cut, however, was perfected in the 20th century with the help of advanced cutting technology that allowed for more precise symmetry and brilliant faceting.
Today, the heart cut remains a symbol of affection, romance, and devotion — making it an ideal choice for engagements, anniversaries, and special occasions.

Are Heart Cut Diamonds a Good Investment?
Heart-cut diamonds are not just romantic — they can also be a solid investment, especially when cut and graded well.

According to a 2024 De Beers Consumer Insight Report, demand for non-round diamond shapes increased by 18%, with heart cuts showing the strongest growth in online engagement.
Their rarity and craftsmanship mean well-cut heart diamonds often hold or increase in value, especially those above 1.5 carats with excellent symmetry and clarity (VS2 or better).
