A gift retailer in a mall town ran out of heart cut moissanite by the second week of January and lost three Valentine custom orders to a shop two stores down. Heart is the most seasonal cut in the catalog: demand concentrates in the six weeks around Valentine's Day and a secondary bump around anniversary and proposal season, and a supplier who waits for the order queue to reorder misses it. Buying heart well means timing the MOQ to the spike, not to the average month, and inspecting symmetry that a brilliant cut buyer never has to think about.
The seasonal math behind heart stockouts
Heart demand is not linear. Roughly half of a year's heart sales land in the six weeks around February, with another 20 percent in the May-to-June proposal window. A buyer who orders heart at the same monthly cadence as oval will be empty by mid-January.
| Window | Share of annual heart demand | Stocking move |
|---|---|---|
| Mid-Jan to late Feb | ~50% | Peak stock, reorder before Dec |
| May to June | ~20% | Refill for proposals |
| Rest of year | ~30% | Lean stock, anniversary gifts |
The MOQ that looks generous in October becomes a stockout in January. Planning the seasonal order in late November is the single highest-return move a heart seller makes.
The heart spec sheet
Heart moissanite ships at Mohs 9.25, DEF color, eye-clean clarity, GRA certified with matching girdle inscription. Shape-specific standards:
- Symmetry checked so the two lobes mirror; lopsided hearts are the most common reason a customer says "it doesn't look like a heart."
- Cleft depth logged — too shallow and the stone reads round, too deep and it pinches the center.
- Length-to-width ratio held near 1.00 for the classic heart, avoiding the stretched or squashed extremes.
- Matched pairs for earrings or pendants selected within 0.05 carat, with both hearts facing the correct orientation.
About 12 percent of bulk heart parcels fail the symmetry check on first pass, which is why we inspect each stone individually and flag matched pairs before packing. We photograph every heart loose on white so a buyer can see the lobe balance before mounting, since a description alone rarely catches a lopsided stone.
How different buyers should plan heart
A small-batch buyer should not run deep heart stock outside the peak. Order 20 pieces in late November for the Valentine push, in the 0.50 to 1.00 carat pendant range where heart demand concentrates, and hold a small reserve for anniversary work.
A gift-focused boutique should add a matched-pair lane for heart studs and drops, which convert well during proposal season. Our DDP export to the US and EU fixes landed cost at PO; because the peak window is fixed, we recommend locking the seasonal reorder in writing by early December so production capacity is reserved before the rush. Reorders on an approved silhouette ship in five business days once the queue is open.
Private-label programs can run a fixed heart silhouette locked across runs, so a Valentine pendant and an anniversary gift bought in different months match. That lock removes the symmetry complaints that usually cluster in February and pushes heart defect returns under 1.5 percent even at peak volume.
Frequently Asked Questions
When should I order heart cut moissanite for Valentine's?
Place the seasonal order by late November and lock it in writing by early December. Roughly half of annual heart demand lands in the six weeks around February, and waiting for January orders means missing the window.
What makes a heart look "off" to a customer?
Lopsided lobes or a cleft that is too shallow or too deep. A well-cut heart has two mirror lobes and a centered cleft. Reject any stone where the lobes do not balance at arm's length.
Do heart cuts make good matched pairs?
Yes, for studs and drops, but only when pre-sorted within a tight carat and ratio spread. Mixed lots should be sold as single pendants, not as a set.
Which carat band sells best for heart?
The 0.50 to 1.00 pendant band is the volume seller. Larger hearts move slowly outside peak and are best kept as a small custom reserve.
What MOQ opens heart wholesale pricing?
20 pieces in one carat band opens the opening rate. Matched pairs carry a four-pair minimum. For the seasonal peak, larger locked orders are quoted separately against the December capacity window.
What to take away
- Heart demand is seasonal — lock the Valentine order in December, not January.
- Inspect lobe symmetry and cleft depth on every incoming stone.
- Anchor with the 0.50 to 1.00 pendant band; keep large hearts as custom reserve.
- Lock a fixed silhouette for private-label Valentine-to-anniversary consistency.
