A Valentine's Day campaign for a gift brand in Seoul nearly failed because the heart moissanite stones in the photo sample looked lopsided — one lobe higher than the other, a cleft that did not sit centered. The buyer had ordered by carat weight from a mixed lot and discovered the problem three weeks before launch. Heart is the one shape where the customer's eye instantly detects asymmetry, because she already knows what a heart is supposed to look like.
Heart cut moissanite is a seasonal and emotional seller — Valentine's, anniversaries, push presents — and it moves when it looks right. Here is the spec that keeps your heart stock sellable.
Why heart is the hardest shape to cut
A heart cut combines two round lobes, a central cleft and a tapered bottom point. Every one of those elements has to sit in the right proportion, or the shape reads wrong. A slightly off cleft, a lobe that is a fraction wider than the other, or a point that angles to one side — all of these are invisible under a loupe but obvious to anyone holding the stone on a chain.
Industry norm for wholesale hearts is to accept stones at the GRA grade and ship them. Our QC adds a human symmetry check, because the certificate does not measure "does this look like a heart."
| Symmetry point | Commodity hearts | Our wholesale heart spec |
|---|---|---|
| Cleft position | Not measured | Centered within 0.1 mm |
| Lobe match | Mixed | Both lobes equal height and width |
| Bottom point | May angle off | Point centered on vertical axis |
| Length-to-width | Mixed | 1.0:1 lock per order |
| Symmetry grade | GRA generic | Visual pass on every stone |
What we inspect on every heart parcel
Heart is a low-yield cut — you lose rough cutting two lobes and a cleft out of a round — so it carries a higher wholesale tier. That price buys you a stone that is worth selling. Before a heart parcel ships, we run each stone through:
- Cleft check: the central cleft must sit on the vertical axis. We measure its position against a center line and reject any stone where the cleft is off-center. An off-center cleft is the most common "wrong heart" complaint.
- Lobe symmetry: the two rounded lobes must match in height and width. We lay stones on a measuring mat and compare lobe outline by outline. A lopsided lobe is visible on a pendant at arm's length.
- Bottom point: the tapered point at the bottom of the heart must sit on the same vertical axis as the cleft. If the point angles to one side, the heart reads crooked on a chain.
- Proportion lock: we ship hearts to a 1.0:1 length-to-width ratio, the classic heart proportion. We can cut elongated or wide hearts on request, but we lock the ratio per order so your tray looks consistent.
How to buy heart moissanite for your line
Gift and Valentine's brands — buy small hearts (5 mm to 6 mm) in sterling silver pendants. The volume moves in the six weeks around Valentine's and Mother's Day. Pre-order in November so your stock lands before the campaign.
Boutique bridal — larger hearts (7 mm to 8 mm) work as anniversary pendants or right-hand rings. Pair with a halo setting to extend the outline and make the heart read bigger.
Private-label programs — lock your heart proportion once. Your pendant CAD file expects a specific cleft depth and lobe curve. We hold that template across reorders so every heart in your campaign matches the hero shot.

Frequently Asked Questions
What size heart moissanite is best for a pendant?
A 5 mm to 6 mm heart is the volume pendant size. It reads as a delicate gift on a chain, works in sterling silver, and suits Valentine's, anniversary and push-present gifting. Larger 7–8 mm hearts move into bridal or right-hand ring territory.
How do you check if a heart moissanite is symmetric?
Look at it face-up. The cleft should sit centered on the vertical axis, both lobes should match in height and width, and the bottom point should line up with the cleft. We inspect every stone on a measuring mat before packing.
Why is heart cut moissanite more expensive?
Heart is a low-yield cut — the cutter loses rough shaping two lobes and a cleft out of a round blank. That lower yield is reflected in the wholesale tier. The higher price is offset by strong seasonal sell-through.
When should I order heart moissanite for Valentine's Day?
Place your bulk order by mid-December so the parcel arrives, is QC'd by your team, and is on the shelf by mid-January. Sample stones ship in 5 business days if you need a photo sample before the bulk run.
What is the MOQ for heart moissanite?
Our wholesale MOQ is 20 pieces per size. Because every heart is symmetry-checked, sample parcels ship within 5 business days.
