JINGYING : Custom Silver Jewelry Facotry provice OEM Service of Iced Stud Earrings Vermeil 18K gold
OEM/ODM jewelry manufacturer design custom your own jewelry
LET’S GET STARTED : mo@kingjy.com
As an OEM/ODM specialist, JINGYING Jewelry heavily prioritizes the streetwear, hip-hop, and urban jewelry markets, where Iced-Out Stud Earrings are a staple product.
For brands looking to supply high-quality, mid-tier luxury alternatives to solid gold and natural diamonds, their combination of 925 Sterling Silver base metal + 18K Gold Vermeil + Moissanite/AAA CZ is one of the most profitable and high-demand product configurations.
💎 Technical OEM Specifications for Iced Studs
When manufacturing iced-out earrings with JINGYING, the product value relies on specific plating thickness and stone-setting techniques to ensure the "iced" effect lasts.
1. 18K Gold Vermeil Standards
To legally be called "Vermeil" in major retail markets (like the US and EU), the plating must meet strict benchmarks which JINGYING applies in their factory:
-
Base Metal: Guaranteed 925 Sterling Silver (Nickel-free, lead-free, hypoallergenic for sensitive ears).
-
Plating Thickness: A minimum of 2.5 microns of solid 18K Gold electroplated over the silver. This is significantly thicker than standard gold flash plating (which is usually less than 0.5 microns) and ensures the gold doesn’t wear off down to the silver after a few wears.
-
Color Tuning: They offer 18K Yellow Gold Vermeil (for a classic bright gold hue) as well as 18K White Gold/Rhodium and Rose Gold variants.
2. "Iced Out" Stone Setting & Materials
The factory specializes in high-density setting styles to minimize visible metal and maximize light refraction:
-
The Stones: You can specify VVS Moissanite (which passes standard diamond thermal testers and has a higher refractive index than diamond) or AAA/AAAAA Cubic Zirconia for tight budgets.
-
Setting Styles:
-
Micro-Pavé: Dozens of tiny 1mm to 2mm stones set closely together using small metal prongs, ideal for iced square clusters, starbursts, or geometric studs.
-
Prong/Halo Settings: A large center stone (e.g., a 1-carat round or princess cut) surrounded by a dense pavé border.
-
Channel/Baguette Layouts: Incorporating step-cut rectangular baguette stones into the design for a modern, architectural hip-hop aesthetic.
-
🏭 Production & Quality Controls
Producing iced earrings requires strict tolerance controls because even a microscopic misalignment in the small prongs will cause stones to fall out during shipping or wear.
-
CNC Machine Carving: For high-volume identical designs, they use computer numerical control (CNC) machining to cut the stone sockets into the silver matrix. This ensures every prong is perfectly identical.
-
Hand Prongs Adjustments: Even with automated casting, workers manually check and tighten the prongs under jewelers' microscopes before the earrings go into the electroplating baths.
-
Threaded Posts (Screw Backs): For iced studs—especially heavier ones—they typically manufacture them with threaded screw-back posts rather than standard friction push-backs to prevent the earrings from falling off.

To get an accurate quote and ensure your custom jewelry design is manufactured exactly as you envisioned, you need to provide a Technical Specification Sheet (Tech Pack) and proper digital design files. Jewelry factories like JINGYING operate heavily on precise measurements, as even a 0.2mm variance can completely change the weight, cost, and durability of a piece.
Here is a checklist of the specifications and files you should prepare before contacting an OEM factory:
📂 1. The Design Files (What They Need to Build It)
You do not necessarily need to be a master CAD designer yourself, but the factory will require one of the following formats to begin:
Option A: The Industry Standard (3D CAD Files)
If you have worked with a jewelry designer, provide the native 3D file. This allows the factory to plug the design straight into their 3D wax printers.
-
File Formats:
.3DM(Rhino),.STL, or.STEP/.STP. -
Note:
.STLis the most universally accepted format for 3D printing, but.3DMis preferred if the factory needs to tweak the file for casting constraints.
Option B: 2D Vector & Technical Drawings (For Factory CAD Creation)
If you don't have a 3D model, the factory can create one for you (often for a fee of $30–$80), but you must provide precise 2D blueprints.
-
File Formats:
.AI(Adobe Illustrator),.DXF, or.PDF. -
Required Views: Front view, side view, and top-down view (Orthographic projection) with explicit millimeter measurements marked.
📝 2. The Technical Specifications (The Jewelry Tech Pack)
Create a document (a simple PDF or spreadsheet) that outlines the exact DNA of the piece. Copy and paste this template for your factory brief:
🏛️ Base Dimensions & Sizing
-
Overall Dimensions: Height, width, and thickness in millimeters (mm).
-
Band/Stem Thickness: For rings, specify the width and thickness at the top vs. the bottom (tapering). For earrings, specify the post gauge (usually 20G or 0.8mm for standard piercings).
-
Size Run: A breakdown of the sizes you want to order (e.g., US Ring Sizes 6, 7, 8; or Earring diameter 10mm, 12mm).
🪙 Metal & Plating Specs
-
Base Metal: Explicitly state the alloy (e.g., Solid 925 Sterling Silver, 14K Yellow Gold, Brass).
-
Plating Material: (e.g., 18K Yellow Gold, Rhodium, Rose Gold).
-
Plating Thickness: Crucial for quality control. Specify in microns (e.g., 0.5 microns for standard fashion jewelry, or 2.5 microns for legal Gold Vermeil).
-
E-Coating: State whether you want an anti-tarnish clear electronic coating applied over the plating.
💎 Stone & Setting Specs (If Applicable)
-
Stone Type: (e.g., VVS Moissanite, AAA Cubic Zirconia, Lab-Grown Diamonds).
-
Stone Cuts & Sizes: Specify the exact dimensions in millimeters, not just carat weight (e.g., "Center stone: 6mm Round Cut; Accent stones: 1.2mm Round Brilliant Cut").
-
Setting Method: How the stones should be secured (e.g., Micro-Pavé, 4-Prong setting, Bezel setting, Channel setting).
🔒 Findings & Mechanics
-
Closures/Backings: For earrings, specify if you want push-backs (butterfly), screw-backs (threaded), or huggie levers. For necklaces, specify the clasp type (e.g., Lobster claw, Spring ring, Box clasp).
-
Branding & Hallmarks: Specify the location and text for laser engravings (e.g., your brand logo on the inside band, alongside the standard "S925" or "14K" purity stamp).
💡 Quick Tips for Smarter OEM Communication
-
Specify Tolerance Limits: Jewelry shrinks slightly during the casting and polishing phase (usually around 1% to 2%). Make sure your tech pack notes whether your listed dimensions are pre-polishing or final desired sizes.
-
Ask for a "Golden Sample": Never greenlight a mass production run based purely on a 3D CAD render. Always pay for a physical prototype (a "golden sample") to check the weight, how the stones catch the light, and how comfortable it is to wear.
