Who this is for
This page serves two groups: jewelry brands and designers who need a manufacturing partner, and individuals who want one ring made to their own design. The process is the same; the difference is order volume and packaging.
For brands and designers
We work as a custom ring manufacturer for brands, designers and retailers. You can use us for OEM (we make to your design), ODM (we develop the design with you) and private label (your logo on the product and packaging). MOQ is 1 piece for the ring itself. Custom logo packaging has an MOQ of 100 pieces. Rings and pendants ship 7–14 days after CAD approval. Payment is full payment before production. Send your sketch, reference image or CAD to start.
For individual buyers
You can order a single custom engagement ring directly from our factory. MOQ is 1 piece. You do not need a technical drawing; a photo or a rough sketch is enough to start. We confirm the design in 3D CAD before production. Rings ship 7–14 days after CAD approval. Payment is full payment before production. We also make pendants and other jewelry, but this page focuses on engagement rings. Contact us on WhatsApp +86 185 2059 5760 or alpha_jewelry@163.com.
Design choices
You choose the metal and the centre stone; the rest of the design is locked at CAD approval. We work with 9K, 10K, 14K, 18K and 22K gold in yellow, white and rose color, Pt950, and 925 silver. We also offer gold plating (vermeil). Centre stone options are natural diamond, lab-grown diamond, moissanite and colored stones. Lab-grown diamonds are DEF color, VVS/VS clarity; centre stones over 0.5 ct come with an IGI report. Moissanite centre stones come with a GRA certificate. All design details are confirmed in the 3D CAD before casting.
14K, 18K or platinum
You can choose 14K gold, 18K gold or Pt950 for a custom engagement ring. Both 14K and 18K gold are available in yellow, white and rose color. Pt950 is available as a separate option. We also work in 9K, 10K and 22K gold, and in 925 silver, and we offer gold plating (vermeil). The metal choice is confirmed at CAD approval. If you are ordering for a brand, the same metal options apply across your line.
Natural diamond, lab-grown diamond or moissanite
We offer three main centre stone types: natural diamond, lab-grown diamond and moissanite. We also set colored stones. Lab-grown diamonds are DEF color, VVS/VS clarity. Centre stones over 0.5 ct come with an IGI report. Moissanite centre stones come with a GRA certificate. Natural diamonds are available as a centre stone option. The stone type and certificate scope are confirmed at CAD approval. If you need a specific certificate for a centre stone, tell us before CAD so we can confirm it is available for that stone.
How a custom order runs
A custom order runs in a fixed sequence: you send a sketch, reference image or CAD; we produce a 3D design and CAD for your approval; we cast, set, polish, inspect and ship. You approve the CAD before casting. After approval, the ring goes to casting, then stone setting, then polishing, then quality control, then shipping. Rings and pendants ship 7–14 days after CAD approval. Payment is full payment before production. We do not start production until the CAD is approved and payment is complete. This sequence applies to both brand orders and single-piece orders.
How to design custom jewelry
You can start a bespoke engagement ring design from a photo, a sketch or an existing CAD. Send the image or file with any notes on metal and centre stone. We turn it into a 3D CAD model and send it to you for review. You check the proportions and details, request changes, and approve the final CAD. Only then do we cast. This is the same path we use for brand clients who need to know how to design custom jewelry for a collection. No technical drawing is required from you; the CAD is our job.
What affects the price
The quote depends on three things: the metal you choose, the centre stone type, and the quantity. Metal options include 9K–22K gold, Pt950 and 925 silver, with gold plating (vermeil) available. Centre stones can be natural diamond, lab-grown diamond, moissanite or colored stones. We do not publish prices because each combination is different. If you are asking how much does custom jewelry cost, send your design and we will quote the exact configuration. Custom logo packaging has an MOQ of 100 pieces and is quoted separately.
Timeline, payment and shipping
Rings and pendants ship 7–14 days after CAD approval. Payment is full payment before production; we do not work on a deposit model. The timeline starts when you approve the CAD and payment is complete. We ship from Guangzhou, Panyu. For brand orders, custom logo packaging has an MOQ of 100 pieces; packaging is produced alongside the jewelry order. We do not publish shipping rates or delivery times beyond the production window because they depend on the destination and carrier. Contact us on WhatsApp +86 185 2059 5760 or alpha_jewelry@163.com for shipping arrangements.

We produce a 3D CAD model from your sketch, reference image or existing CAD. You review the model and request changes until the proportions and details are correct. You then approve the final CAD.

The CAD is confirmed before casting, so the final ring matches the approved model. Rings ship 7–14 days after CAD approval.
No. We do not resize rings after delivery. The ring size must be confirmed before CAD approval, because the CAD locks the dimensions. If you are ordering for a client, confirm the size with them before you approve the CAD. We cannot change the size after the ring has shipped.
