Exceptional Surface Finish
Exceptional surface finishing is the soul’s garment for jewelry. Nanding meticulously crafts multiple top-tier techniques to imbue each of your designs with unique texture, color, and enduring vitality. Below are Nanding’s core surface finishing solutions for you.
Silver Structure Diagram
E-Coat (Electrophoretic Coating)
The outermost protective coating, formed by an electrophoretic process to create a uniform protective film that effectively enhances the wear resistance and oxidation resistance of silver jewelry, extending its service life.
Plating
A metal plating layer that provides excellent gloss and texture, which is key to the aesthetic appeal of silver jewelry. Different metal materials can be selected according to requirements.
925 Silver (Base Layer)
A standard silver alloy with 92.5% silver content, serving as the structural base to provide necessary hardness and ductility, ensuring the durability and shape stability of silver jewelry.
Design Intent
Aesthetics
Showcases the luster and noble texture of silver jewelry through metal plating to meet visual aesthetic requirements.
Durability
The 925 silver base provides structural strength, ensuring the jewelry is not easily deformed or damaged during daily wear.
Protection
The outer electrophoretic coating forms a protective barrier, effectively preventing oxidation, wear, and chemical erosion.
Rhodium Plating: Ultimate Protection & Whitening for Silver Jewelry
Rhodium is one of the rarest and most expensive members of the platinum family, offering exceptional corrosion resistance and brilliant white luster
Ultimate Tarnish Resistance
Completely blocks air and sulfides, preventing silver from blackening, maintaining permanent brightness.
Enhanced Hardness
Rhodium layer is highly durable with wear resistance more than twice that of pure silver, providing excellent protection.
Biocompatibility
Hypoallergenic, suitable for sensitive skin, comfortable to wear without irritation.
Eternal Brightness
Maintains lasting bright white color that doesn't fade with time, always looking new.
Rhodium Plating Thickness Recommendations
Choose the appropriate plating thickness based on jewelry type and usage scenario
Fast Fashion
Low-cost, short-term use fashion jewelry
Low-Wear Jewelry
Pendants, earrings with minimal contact
Daily Wear Silver
Highly recommended thickness, balancing protection and cost
High-Wear Areas
Rings and other frequently contacted areas
Choosing the right rhodium plating thickness can significantly extend jewelry life. For daily wear, 0.1-0.2 μm is recommended.
Rhodium Plating is Especially Suitable For
Silver jewelry requiring long-term brightness
Frequently worn daily jewelry
Sensitive skin allergic to nickel
Heirloom or high-value silver jewelry
Precision Process: Revealing the Complete Jewelry Electroplating Journey
Professional electroplating is the perfect combination of art and science, with each plated piece undergoing multiple carefully designed stages
Surface Preparation
Thorough cleaning and polishing to remove all grease, oxides and impurities, creating a perfect foundation for plating
Rinsing & Activation
Multi-stage rinsing ensures absolute surface cleanliness, activation treatment enhances metal surface activity
Electroplating
Through electrolysis, target metal ions evenly deposit on the jewelry surface
Thickness Monitoring
Real-time monitoring of plating thickness ensures compliance with design specifications and durability requirements
Post-treatment Rinsing
Removal of residual plating solution to prevent corrosion and discoloration
Drying & Curing
Professional drying process ensures complete stabilization of the plating layer
Process Essence
Excellent plating results from strict control of every detail - precise chemical ratios, constant temperature control, appropriate current density, and supervision by experienced technicians.
Quality Assurance
Each plating stage has strict quality control points to ensure the final product meets the highest standards. We use advanced testing equipment to comprehensively evaluate plating thickness, uniformity and adhesion.
Extend Jewelry Life: Professional Care & Maintenance Guide
Proper care not only maintains the beauty of jewelry but also significantly extends its lifespan
Daily Care Core Principles
Wearing Order
Put on jewelry only after cosmetics and perfume have completely dried to avoid direct contact of chemicals with the plating
Avoid Contact
Keep away from chemicals, salt water, chlorinated water and extreme temperatures; remove jewelry when swimming or bathing
Regular Cleaning
Gently wipe with a specialized cleaning cloth to maintain jewelry shine; avoid using harsh chemicals
Professional Inspection
Undergo professional inspection and maintenance annually to promptly identify and fix potential issues
Professional Cleaning Guide
Preparation
Prepare a soft cleaning cloth, warm water and mild soap. Ensure the work area is clean to prevent accidental dropping of jewelry.
Gentle Cleaning
Gently wipe the jewelry surface with a soft cloth dipped in mild soapy water, paying special attention to crevices and details.
Thorough Rinsing
Rinse the jewelry thoroughly with clean water to ensure all soap residue is removed.
Complete Drying
Gently pat dry the jewelry with a soft, lint-free cloth, ensuring it's completely dry before storage.
Professional Storage Recommendations
Individual Storage
Store each piece of jewelry separately to avoid scratches and wear from rubbing against each other.
Specialized Containers
Use jewelry boxes with soft linings; avoid direct contact with plastic bags or paper products.
Environment Control
Store in a cool, dry place away from direct sunlight and humid environments to prevent plating oxidation.
Professional Maintenance Reminder
Seek professional maintenance when jewelry shows the following conditions: significant plating wear or peeling, discoloration that cannot be restored through regular cleaning, structural damage or loose gemstones, and preventive maintenance every 1-2 years.
