At Shinma, we believe your body jewelry is a canvas for self-expression. Beyond the form of our pieces lies a world of color, achieved through a fascinating scientific process called electroplating. This guide will demystify how we transform metal hues and help you choose the perfect shade for your unique style.

What is Electroplating? The Science Behind the Shine

Electroplating is an advanced method where we coat your jewelry with an ultra-thin layer of another metal through precise electrochemical processes. Think of it like giving your piece a new, durable skin of color. Here's how it works in our studio:

Preparation: Your Shinma piece undergoes meticulous polishing and precision cleaning. We employ ultrasonic cleaning and electrochemical preparation to ensure a flawless base, as any imperfection would be visible under the new layer.

The Bath: The jewelry is immersed in a specialized electrolyte solution containing ions of precious metals. Our solutions include gold potassium cyanide for gold plating, rhodium sulfate for rhodium plating, and ruthenium-based solutions for black finishes.

The Current: We apply precisely controlled electrical currents through our advanced rectifier systems. Your jewelry acts as a cathode, attracting metal ions from the solution with exact deposition rates.

Transformation: Through molecular bonding, these ions create a smooth, even metallic coating with thicknesses ranging from 0.5 to 5 microns, ensuring both beauty and durability.

We electroplate for multiple purposes: providing tarnish resistance (especially for silver), adding protective barriers, concealing minor seams, and most importantly - offering you an incredible spectrum of customizable colors.

A Spectrum of Possibilities: Mastering Voltage and Chemistry

The secret to achieving different colors lies in our precise control of electrical parameters and specialized chemical formulations. Our technicians expertly manipulate voltage, current density, and solution composition to create specific color effects.

Advanced Color Technologies

Our Rhodium plating (cool ultra-white shine) uses sulfate-based solutions at specific pH levels below 1, while our Black Ruthenium achieves its edgy modern look through specialized ruthenium-based electrolytes with organic additives. Each finishing process has its own optimized voltage setting and technical parameters.

How to Choose Your Custom Color

Selecting your perfect plating color involves several considerations:

Skin Tone Harmony:

• Warm undertones (greenish veins): Complemented by rose gold and yellow gold

• Cool undertones (bluish veins): Enhanced by white gold and rhodium

• Neutral undertones: Versatile across all color options

Style Personality:

• Classic elegance: Rich Yellow Gold (12-18V)

• Modern minimalism: White Rhodium (18-24V)

• Edgy contemporary: Black Ruthenium (36-48V)

• Vintage romantic: Rose Gold (12-24V)

• Bold statement: Colored Titanium (108-120V)

Wear Considerations:

• High-friction items (rings, bracelets): Choose thicker deposits (2-5 microns)

• Low-contact pieces (earrings, pendants): Opt for thinner finishes (0.5-1 micron)

• Sensitive skin: Select nickel-free options like gold or rhodium

At Shinma, we're not just selling jewelry; we're providing a platform for personal identity. Our electroplating process ensures your chosen color becomes a permanent part of your piece's story through molecular-level bonding.
