A Marquise Cut Lab Grown Diamond order is not one lead time. It is a calendar: sample days, stone sourcing, casting, setting, plating, QC, pack and freight. Buyers who plan backwards from a retail event never miss the shelf.
The Marquise Cut Lab Grown Diamond production calendar
Day 1-5: sample approval. Day 6-10: stone sourcing and casting. Day 11-14: setting and polish. Day 15-16: plating. Day 17: QC. Day 18: pack. Day 19-20: handover to freight.
| Day | Step | What buyer sees |
|---|---|---|
| 1-5 | Sample approval | Signed first article |
| 6-10 | Cast and source stone | Weight, grade photos |
| 11-14 | Set and polish | Bench photos |
| 15-16 | Plate | Micron reading |
| 17 | QC | AQL log |
| 18-20 | Pack and handover | Carton photos |
A new mould adds five to seven days. A custom plating colour adds two days. A rush order cuts the sample step but cannot cut the QC step.
Most missed Marquise Cut Lab Grown Diamond deadlines are not production delays. They are approval delays. A sample approved verbally, then argued about, eats ten days of the calendar.
Ocean freight is the cheapest line, but it is the line you forget. A Marquise Cut Lab Grown Diamond carton that clears customs in three days in May takes twelve days in December.
Air freight is not expensive if you only ship the fast-mover. Split the 500-piece order: 100 by air for the launch, 400 by ocean for the reorder.
A new mould is not a delay. It is a week of CAD, a week of casting, and a week of adjustment. Plan it into the calendar from day one.
Working backwards from a retail date
If your event is November 1, order Marquise Cut Lab Grown Diamond by October 1 at the latest. Ocean freight to the US east coast adds twenty-five to thirty days. Air freight adds five days but costs three to four times more.
Most buyers who miss a holiday shelf did not order too late; they ordered without a sample approval step, then had to re-make.
Rush orders are a tax. 15 to 20 percent for overtime, and the QC step still runs. If you are paying rush twice a year, plan earlier.

What slips the Marquise Cut Lab Grown Diamond timeline
Three things slip the calendar. First, a stone lot that does not pass colour match. Second, a plating bath change mid-run. Third, a sample approved verbally, not in writing.
A written first-article approval stops the first two. The third is the most common cause of a two-week delay on a Marquise Cut Lab Grown Diamond order.
