A heart-shaped diamond is one of the most personal and romantic centre stones available. It is essentially a pear with a cleft cut into the top. Symmetry is everything. Both halves of the heart must mirror perfectly. Anyone choosing a deeply personal, openly romantic engagement ring or pendant.
Best settings for a heart shape centre stone
A V-prong protects the point at the bottom; two prongs hold the lobes at the top. A solitaire lets the heart shape do everything; a halo adds a frame of smaller diamonds and makes the centre look 25–30% larger; a three stone setting flanks the centre with two accent diamonds.
What to expect on the finger
We recommend at least 0.75 ct for the heart shape to read clearly on the finger. Most Riyanika customers choose between 1 ct and 2 ct for a heart shape centre. Lab-grown diamonds give you the same brilliance as a mined diamond at roughly 40–60% of the price, which means you can comfortably size up the centre stone.

Frequently Asked Questions
How big does a 1 ct heart shape diamond look?
We recommend at least 0.75 ct for the heart shape to read clearly on the finger. On an average size 6 finger this reads as a confident, well-proportioned centre stone.
Is a heart shape diamond more expensive than a round?
Round brilliants typically cost 15–25% more than fancy shapes (oval, emerald, pear, cushion, etc.) at the same carat weight and grade. The premium reflects how much rough diamond is wasted to cut a round vs a fancy shape.
What setting works best with a heart shape cut?
A V-prong protects the point at the bottom; two prongs hold the lobes at the top. A solitaire is the most popular for letting the shape speak for itself; a halo is the most popular for making the centre look larger.
Are lab-grown diamond heart shape diamonds GIA-certified?
Every centre stone above 0.30 ct is GIA-certified and laser-inscribed with its grading report number.
