To source custom 3D stainless steel charms in the 10–20 mm range, define the finished dimensions, front and back design, attachment opening, material grade and finish before requesting a quotation. Then approve a physical sample at actual size before authorizing bulk production. A front-view image alone leaves important questions about depth, weight and assembly unanswered.
yanluojewelry is the jewelry wholesale brand of Guangzhou Yanluo Industrial Co., Ltd., established in 2015 and based in Guangzhou, China. Our team handles stainless steel jewelry wholesale and OEM/ODM inquiries. For each small custom charm project, our team first reviews your design to confirm feasibility, component materials, MOQ and sample terms.
What Should a 10–20 mm Charm Specification Include?
Start by stating whether the requested height includes the top loop or bail. For example, a 15 mm charm body and a 15 mm overall charm are different specifications. Next, give width and depth separately, and mark the dimensions on a drawing.
- Finished size: body height, overall height, width and maximum depth in millimeters.
- Views: front, back and side references showing the intended shape.
- Construction: flat back, raised relief or a fully three-dimensional design; solid or hollow where applicable.
- Attachment: fixed loop, separate bail or another connection, with its opening dimensions and orientation.
- Material: requested grade for the charm and each separately supplied connector.
- Surface: polished or textured areas, finish color and any areas requiring a different treatment.
- Order breakdown: quantity for each design and finish, plus whether assembly is included.
If you request 316L stainless steel charms, ask the supplier to confirm the specified grade for the proposed construction. However, a stainless steel catalog description does not establish that every charm, jump ring or bail is 316L.
Raised Relief or Fully 3D: Which Design Do You Need?
A relief charm has a raised design on a base surface. In contrast, a fully 3D charm has shape around its sides and back. Therefore, show the intended rear view so the supplier can evaluate the complete geometry.
Review Small Details at Actual Size
A detail that looks clear in an enlarged rendering may be difficult to distinguish on a small finished charm. For this reason, ask the supplier to identify fine lines, narrow openings or projecting details that may require adjustment. Then review the proposed changes before approving CAD or tooling.
For example, if your concept is a 12 mm sculpted charm, confirm which facial features, lettering or textures must remain visible. An actual-size printout helps you review proportions. However, you still need a physical sample to assess the manufactured result.
Confirm the Back and Wearing Orientation
First, specify whether you want a smooth, textured, recessed or decorated back. Also explain how the charm should face during wear. Finally, check the assembled sample from the front and side to assess its hanging position.
Will the Charm Fit Your Chain or Bracelet?
Give the supplier the dimensions of the component that must pass through the opening. However, chain width alone may be insufficient if an end fitting is larger. For a jump-ring connection, also confirm ring wire thickness, internal opening and the ring closure method.
For a removable charm, test the complete connector and chain combination. If you need a fixed charm instead, approve the attachment position and assembly method. In either case, a loose charm sample cannot demonstrate the fit of a finished necklace or bracelet.
If you are sourcing chain separately, use our stainless steel chain by the metre buying checklist to prepare the matching chain specification.
How Should You Specify Silver, Gold and Black Finishes?
Distinguish polished uncoated stainless steel from a coated silver-tone finish. Next, for gold-tone or black charms, ask the supplier to name the proposed coating process and confirm whether they can use PVD for your design.
Approve a physical color reference together with surface texture. If you specify coating thickness, also ask which layer the supplier measures, which method they use and what acceptance criteria apply. Finally, record any matching requirement between the charm, bail, chain and clasp.
See our PVD coating thickness guide for wholesale buyers for questions to include in your inquiry.
What Affects MOQ and the Custom Charm Quotation?
Ask for MOQ per design and per finish. However, an order of several designs does not automatically meet the minimum for each individual design. Also confirm whether silver, gold-tone and black versions can share any production steps and how that affects the quotation.
- Existing design modification or development of a new shape.
- Geometry, finished dimensions and detail requirements.
- Material grade and proposed manufacturing route.
- Tooling, sampling and revision requirements.
- Finish colors and quantity per variant.
- Loose components or assembled, individually packed jewelry.
Request separate figures for development, tooling, samples, unit production, assembly, packaging and shipping where applicable. In addition, agree on ownership and reuse terms for custom tooling and design files. After reviewing the specifications, Yanluo confirms custom-project MOQ, costs and schedules.
What Should You Check Before Approving the Sample?
- Measure the finished charm: compare body size, overall size, depth and opening dimensions with the approved drawing.
- Inspect all views: check the back, edges, small details and attachment area as well as the front.
- Test assembly: fit the intended chain or connector and inspect hanging direction and movement.
- Compare appearance: review color, texture and visible marks under agreed lighting conditions.
- Record approval: identify the sample revision, agreed tolerances, unresolved changes and inspection criteria.
A sample confirms the appearance and fit of that sample. However, you should also review material documentation and any required product-specific test results separately. For the wider development process, explore our OEM and ODM jewelry services.
Frequently Asked Questions
Can I use a reference photo to request a custom 3D charm?
Yes, it can start a feasibility discussion. To help the supplier assess your idea, add the target dimensions and front, back and side references. Before production, confirm the complete design and use artwork you own or are authorized to reproduce.
Is a 10–20 mm size suitable for every 3D design?
No. Suitability depends on the geometry, detail, attachment and intended use. Therefore, ask for a design review and evaluate an actual-size sample before committing to the final specification.
Can I specify 316L for the charm and its connectors?
Yes. List the required grade for each component in the inquiry. Then ask the supplier to confirm availability, feasibility and supporting documentation for the selected design.
Can I mix several designs to meet the MOQ?
Ask for the minimum per design and finish. However, a combined order quantity does not establish that every variant meets its production minimum.
Does a 3D rendering replace a finished metal sample?
No. A rendering helps review geometry. However, you need a finished sample to assess the manufactured detail, surface, color, connection and wearing orientation.
