A short history
A cutter’s dare for five centuries: the hardest symmetry in the trade. Mary Queen of Scots sent one to Elizabeth I, which settled nothing.
DIAMOND SHAPE
Heart
Hardest shape to cut well and the easiest to cut badly. Symmetry is the whole argument. We only take the symmetrical ones.

PRICES AS OF 16 AUG 2026How it wears
Symmetry is everything; a lopsided heart cannot be unseen. We reject most of what we are offered. Under a carat the shape blurs, so we buy them larger.
The setting it wants
Three prongs, one at the cleft and one at each lobe, or a bezel. Strongest as a pendant, where the shape reads at every distance.
What ratio should a heart diamond be?
We buy 0.98 to 1.05. Outside that window the shape starts reading as a different cut, or worse, as a mistake. The passport lists exact millimeter dimensions so you can check our judgment.
How many facets does a heart cut have?
56 to 58. More facets mean more sparkle but smaller flashes; fewer mean bolder, slower light. Neither is better; they are different personalities.
Is heart more expensive per carat?
Fancy shapes like this cost less per carat than rounds, because less rough is lost and fewer buyers compete for them. Same material, better math.
Natural or lab grown in this shape?
Both, cut to the same standard. Lab rough makes larger heart stones attainable; the passport names the origin either way, in the same type size as everything else.
