Direct answer: The right moissanite wholesale supplier is certified (GRA-certified stones), transparent about MOQ and lead times, willing to send samples before bulk, and able to show you its own factory. Ask the 10 questions below before you commit — they take five minutes and can save you from a bad first order.

Sourcing moissanite jewelry wholesale is different from buying finished retail stock. You are betting on a long-term partner: quality consistency, honest lead times, and what happens when a batch arrives with defects. As a moissanite and 925 sterling silver manufacturer in Haifeng (Meilong), Guangdong, China with 10+ years in the industry, we answer these questions every day — so we wrote the checklist buyers should actually use.

The 10 questions every wholesale buyer should ask

1. Are your moissanite stones certified, and by whom?

Real moissanite should come with a grading certificate. The common one in the industry is GRA (Gemological Research Association) — every Jovelira moissanite piece ships with its GRA appraisal certificate, and we also offer third-party inspection (SGS / TÜV SÜD) on request. If a supplier cannot show any certification, treat that as a red flag: you may be getting CZ (cubic zirconia) or glass sold at moissanite prices.

2. What is your MOQ?

MOQ tells you whether the supplier is built for serious wholesale or just dropshipping one-off pieces. Our MOQ is 1 piece for in-stock styles — useful when you want to test a few designs before committing to volume. For custom (OEM/ODM) production, MOQ depends on the design, and we will quote it upfront with the price.

3. How is your moissanite quality graded?

Moissanite is graded on color, clarity, and cut just like diamond. Ask which grade range your stones fall into (we supply VVS clarity, D-E-F color range as standard for our wholesale lines). A supplier that cannot describe its stone quality is usually buying mixed stock from traders rather than controlling quality at source.

4. What materials do you actually work with?

For silver jewelry, the key question is 925 sterling silver (S925) — check that the base metal is stamped and that plating (rhodium, 18K gold) is specified. At our 1,115㎡ factory in Haifeng, Meilong — one of China’s established jewelry production hubs — casting, stone setting, plating and polishing all happen in-house, so material quality is controlled from ingot to finished piece.

5. Do you offer OEM / ODM / private label?

If you plan to build a brand, you need a supplier that can customize: send a photo, sketch, or 3D file and get a quote. We offer OEM/ODM with private label packaging, and our design team covers CAD modeling and 3D printing before casting If you are planning to expand into lab-grown later, our guide to building a lab-grown diamond collection explains how the same OEM/ODM workflow applies.

6. Can I get a sample before bulk? What does it cost?

A reliable supplier will always offer samples. Our sample lead time is 3–5 working days, sample cost is credited back or discounted on your bulk order, and samples ship with the same quality inspection as bulk. Never place a large first order without seeing a physical sample.

7. What is your production lead time for bulk orders?

Get this in writing before ordering. Our bulk production is 15–20 working days after sample approval and deposit, and we confirm the date in the PI (proforma invoice). Suppliers that only say “asap” usually have no production plan.

8. What is your quality inspection process?

Ask what checks happen before shipment. We 100% inspect every piece — stone setting firmness, plating quality, and polish — and provide photos/videos of your batch before shipping. If the supplier cannot describe its QC process, your defect rate will be a surprise.

9. What is your policy for defective items?

Even good factories have occasional defects. The right answer is a clear replacement policy (we replace defective pieces and cover the issue in the after-sales process). Avoid suppliers that require you to ship defects back at your own cost before any resolution.

10. Can you show me your factory?

A real manufacturer can show its workshop — live video tours are common practice now. We have 50 craftsmen across casting, setting, plating, and polishing departments, and we are happy to arrange a video call walkthrough. If a supplier has no factory to show, you are likely dealing with a trader.

Red flags to avoid

• No certification for the moissanite stones (high risk of CZ substitution)
• Stock photos only — no factory images, no real production videos
• Suspiciously low prices — quality moissanite + S925 has a real cost floor
• Vague lead times and MOQ — no written PI or production schedule
• No sample policy — they want your bulk order before you see the product
