JINGYING: Custom OEM Silver Jewelry Maker – The Bracciale Tennis Misto with Cubic Zirconia, 18K White Gold Plated

Introduction: The Evolution of Tennis Bracelet Manufacturing

Few jewelry designs have achieved the enduring popularity of the tennis bracelet. Its continuous line of sparkling stones, set in a flexible metal framework, represents a perfect marriage of elegance and wearability. When this classic design is reimagined through the lens of custom OEM manufacturing—combining 925 sterling silver, brilliant cubic zirconia stones, and a luxurious 18K white gold plating—the result is a piece that rivals fine jewelry at a fraction of the cost.

JINGYING, with 23 years of expertise in the jewelry manufacturing industry, has mastered the art of producing such high-quality custom pieces for global brands, retailers, and designers. The Bracciale Tennis Misto (Mixed Tennis Bracelet) in 925 silver with cubic zirconia and 18K white gold plating exemplifies the company’s commitment to craftsmanship, customization, and quality assurance. This article explores the intricate manufacturing process, material selection, and customization capabilities that make JINGYING a trusted OEM partner for this signature piece.

Understanding the Product: Materials and Design

The Foundation: 925 Sterling Silver

At the heart of the Bracciale Tennis Misto lies 925 sterling silver, an alloy composed of 92.5% pure silver and 7.5% copper. This composition achieves an essential balance: pure silver provides the brilliant white luster and excellent workability that jewelers prize, while copper adds structural integrity for everyday durability. Pure silver alone is too soft for jewelry applications—it bends, scratches, and cannot reliably hold gemstones in place. The copper content creates a metal that maintains silver’s aesthetic qualities while offering the strength required for secure stone settings and reliable clasp mechanisms.

JINGYING sources ethically refined 925 silver grains, ensuring compliance with international standards and certifications such as RJC (Responsible Jewellery Council). The material is hypoallergenic, making it suitable for consumers with sensitive skin.

The Brilliance: Cubic Zirconia Stones

The tennis bracelet’s defining feature is its continuous row of gemstones. Cubic zirconia (CZ) serves as the ideal accent stone, offering diamond-like brilliance at an accessible price point. As a synthetic gemstone, CZ provides consistent quality, clarity, and color that natural stones cannot guarantee. Its optical properties—high refractive index and dispersion—create the fire and sparkle that make diamond simulants so appealing in fashion jewelry.

For the Bracciale Tennis Misto, JINGYING typically sources AAA-grade cubic zirconia stones, representing the highest quality available in the market. These stones are laboratory-crafted with extreme precision, ensuring no imperfections and exceptional light reflection.

The Luxury Finish: 18K White Gold Plating

The final layer that transforms the Bracciale Tennis Misto into a luxury piece is the 18K white gold plating. This plating serves both aesthetic and protective functions:

Aesthetic enhancement: White gold plating provides a bright, cool-toned finish that complements the cubic zirconia stones, creating a cohesive, sophisticated appearance.

Protection: The plating acts as a barrier against tarnishing, preserving the piece’s luster and prolonging its lifespan.

Hypoallergenic barrier: For wearers with silver sensitivities, the gold plating provides an additional protective layer between the skin and the base metal.

JINGYING employs high-quality electroplating methods, typically applying gold plating thicknesses ranging from 0.5 to 3 microns, customizable based on client requirements. The company performs two-time plating on all sterling silver jewelry—first applying a thick silver base layer to ensure surface smoothness, followed by the real gold plating, with thickness up to 3 microns to ensure durability for up to one year of regular wear.

The Custom Manufacturing Process

From Concept to CAD Design

The journey from design concept to finished bracelet follows JINGYING’s structured custom manufacturing workflow:

1. Design Submission: Clients provide design ideas through various mediums—hand-drawn sketches, photographs of existing pieces, or digital designs. The company accepts concepts ranging from simple sketches to detailed technical specifications.

2. Feasibility Analysis: JINGYING’s technical team assesses the design for manufacturability, evaluating factors such as structural integrity, stone setting requirements, and production feasibility. This stage includes cost estimation based on design complexity and material requirements.

3. CAD Modeling: Using advanced jewelry CAD software like Matrix Gold, RhinoGold, and ZBrush, designers create precise 3D digital models. For the Bracciale Tennis Misto, this stage involves:

• Creating base structure from 2D outlines
• Adding details like stone settings and engravings
• Ensuring accurate bracelet length and stone spacing
• Generating photorealistic 3D renders for client approval

4. Client Review and Revisions: Clients receive photorealistic 3D renders for approval. Adjustments—modifications to thickness, stone placement, or bracelet dimensions—can be made at this stage before physical production begins.

3D Prototyping

Once the CAD design receives final approval, JINGYING produces a physical prototype:

Technology Selection: Depending on the design requirements, the company employs appropriate 3D printing technologies:

• SLA (Stereolithography): For high-detail pieces
• Wax Printing: For investment casting preparation

Printing Process: The CAD file is exported as an STL/OBJ format, support structures are added for overhangs, and the prototype is fabricated layer by layer.

Post-Processing: After printing, prototypes undergo support removal and sanding/polishing to achieve a flawless finish.

Casting and Manufacturing

For the Bracciale Tennis Misto, JINGYING employs investment casting (lost-wax casting), the industry standard for producing high-quality sterling silver jewelry:

1. Mold Making: The wax prototype is coated in a ceramic slurry, creating a heat-resistant mold.

2. Burnout: The mold is heated, melting the wax and leaving a hollow cavity in the exact shape of the design.

3. Silver Casting: Molten 925 silver is poured into the hollow mold under vacuum conditions to minimize porosity and ensure complete fill of intricate details.

4. Devesting: Once cooled, the ceramic mold is broken away, revealing the raw silver casting.

Post-Casting Processing

The raw casting undergoes several essential processing steps:

Deburring: Removes rough edges and flash from the casting process, ensuring smooth surfaces that won’t snag clothing or irritate skin.

Annealing: Heat treatment strengthens the silver, reducing brittleness and improving workability.

Assembly: For the Bracciale Tennis Misto, this involves soldering individual link segments together, forming the complete bracelet structure, and attaching the clasp mechanism.

Stone Setting

The cubic zirconia stones are set into the bracelet using specialized techniques. JINGYING employs Micro-inlaid machines imported from Japan for precision setting of 5A CZ stones. This technology enables the company to achieve a 99% no-lost-stone rate using wax-setting technology. Each stone undergoes individual verification to ensure it is firmly seated and properly aligned.

Plating Process

The 18K white gold plating is applied through JINGYING’s two-step electroplating process:

1. Base Silver Plating: A thick silver layer is applied to ensure surface smoothness.

2. Gold Plating: The 18K white gold layer is electroplated over the silver base, achieving the desired thickness (customizable from 0.5 to 3 microns).

The company provides clients with machine-test reports verifying plating thickness meets their specifications.

Quality Assurance: Ensuring Excellence

Rigorous Testing Protocols

JINGYING maintains ISO 9001 certification, adhering to internationally recognized quality management standards. For the Bracciale Tennis Misto, quality control is conducted at every stage of production by a dedicated 10-engineer quality team.

Stone Security Testing: Each stone is individually tested using professional steel needles to ensure it will not fall out. Additionally, jewelry items are dropped from 3 meters to simulate accidental impacts and verify stone security.

Plating Quality Testing: The company conducts rigorous machine tests to verify plating thickness meets client standards. Professional tools are used to manually rub the metal surface for five minutes, ensuring coating quality.

Material Verification: XRF (X-ray fluorescence) analysis confirms the metal composition, ensuring it contains the specified 92.5% silver content.

Warranty and Quality Guarantee

JINGYING stands behind its craftsmanship, offering 3-6 months warranty against non-human reasons for quality issues such as color change or stone loss.
