What is E-Coating Jewelry and How It Works?

Author: Jewepiter Team

1. What is E-Coating Jewelry?

E-coating, also known as electro deposition or electro coating, is a popular process in the jewelry industry. It involves covering an object in a fine layer of lacquer using electric currents. 

This process, if done correctly, results in a consistent, even, and unnoticeable layer that enhances the durability and aesthetic appeal of the jewelry.

2. How Does E-Coating Work?

The e-coating process may vary slightly from one jeweler to another, but generally, it involves the following steps:

  1. Cleaning and Polishing: The jewelry piece is first cleaned and polished to ensure it’s free of any dirt, scratches, or other imperfections.
  2. Rinsing: The piece is then rinsed in distilled water to wash away any remaining debris.
  3. Submersion and Electro Coating: The jewelry is submerged in a solution of water and e-coating. An electric current is passed through the solution, causing the e-coating to stick and fuse to the metal.
  4. Heating: The jewelry is heated in a kiln or oven to harden the e-coat and give it a clear glossy appearance.
  5. Final Polishing: The piece is polished once more to get ready for sale.

3. Why Should You E-Coat Your Jewelry?

E-coating offers numerous benefits, making it a popular choice for jewelry designers and sellers alike. Here are a few reasons why you should consider e-coating your jewelry:

  • Protection: E-coating provides an extra layer of protection to prevent scrapes, scratches, tarnishing, and other forms of wear and tear.
  • Design Flexibility: E-coating allows for the creation of unique and colorful jewelry pieces. Unconventional colors like blue, purple, and red can be achieved, allowing jewelry to retain its metallic feel unlike clay or enamel.
  • Complex Designs: E-coating involves completely submerging the metal part of a design, making it possible to coat even the most complex objects.

4. Things to Consider Before You E-Coat Your Jewelry


Before you embark on the e-coating process for your jewelry, there are several factors to consider:

Metal Type

E-coating is most effective on standard metals such as brass, silver, and gold. 

Lower-cost metals, often used in costume jewelry, may be susceptible to damage from the high temperatures and electric current involved in the process. 

Occasionally, metals like titanium and neobium are used, but they’re harder to coat and some manufacturers may refuse them.

Jewelry Design

E-coating uniformly covers your jewelry with a thin lacquer layer. However, it may adversely affect components that are unsuitable for the process. 

Elements like faux gemstones, enamel, or plastic parts could potentially melt or discolor due to the heat or electric current. If your jewelry includes these components, it’s advisable to add them after the e-coating process.

Desired Color and Finish

E-coating is not easily removable and could increase the defect rate if not applied correctly. 

The color of e-coated jewelry may not be easily discernible, but an experienced expert can identify them. For instance, silver with e-coating will not appear as natural and will be slightly darker in shade compared to the original silver metal color. 

Therefore, it’s crucial to be certain of your color and finish choices before e-coating your jewelry.

The Cost of E-Coating

E-coating has different prices depending on how complicated the jewelry piece is, what kind of e-coating is used, and how much polishing work is needed. 

Polishing is very important; otherwise, any scratches will show up clearly under the e-coating, which is not completely opaque. 

The polishing cost may be the same as for normal jewelry metals like silver, gold, and platinum, but it may be higher for harder metals like stainless steel and tungsten, because they need special equipment.
