What this collection covers

This collection holds 0 ready wholesale designs of lab grown diamond supplier built around lab grown diamond. Chemically, optically and physically identical to mined diamond, at 10 Mohs with 2.42 refractive index. Every piece is made in our own 6,000 m² facility in Wuzhou, Guangxi — cutting, setting, polishing, quality control and packing all happen under one roof, so pricing, lead time and repeat-order consistency stay predictable.

How wholesale pricing works

Prices shown are per piece at the entry quantity. Volume tiers apply automatically to your quotation: 50–199 pcs saves 8%, 200–499 pcs saves 14% and 500+ pcs saves 20% against list. Because we are the manufacturer, the tier is calculated from factory cost rather than a distributor margin — which is usually where a 20–35% landed-cost difference appears between us and a trading company.

Quality control before packing

  1. Incoming stone grading. Every parcel is checked for colour, clarity and measurement against the order sheet before it enters the setting line.
  2. In-process inspection. Setters check prong security, stone alignment and surface finish at each station.
  3. Final QC under 10× magnification. Polish, plating thickness, clasp and hinge function, and hallmark accuracy are verified piece by piece.
  4. Ultrasonic cleaning and packing. Pieces are cleaned, photographed against your PO number and packed in individual poly bags inside export cartons.

Questions about Lab Grown Diamond Supplier

What is the minimum order quantity for lab grown diamond supplier?

Standard MOQ is 10 pieces per design, and mixed-design wholesale lots start at 50 pieces across the range. For 363 ready designs you can combine styles in a single order to reach the next price tier.

Are the stones certified?

Every parcel can ship with GRA certification. Stones are graded before setting, and each certificate is matched to the stone with a grading sheet and photographs so your buyer can verify it independently.

Can I mix metals and stone grades in one order?

Yes. You can mix 925 sterling silver, 10K, 14K and 18K gold in the same production run, and specify D–H colour with VVS–SI clarity per line. We confirm every combination on a single approval sheet before production starts.

How long does production and delivery take?

Stock designs leave our Wuzhou workshop in 7–15 days. Custom or certified runs take 10–20 days depending on quantity and setting complexity, and express delivery by DHL, FedEx or UPS adds 3–7 days to Europe and North America.

Can you produce these to my own design?

Yes. Send a sketch, CAD file, reference photo or a physical sample and our CAD team returns a 3D rendering and quotation within 48 hours. OEM production starts from 30 pieces per design, including private-label engraving and packaging.
