What Is Gold Plating
Gold plating is an electrochemical electroplating process that deposits a thin, even layer of pure gold onto the surface of base metals such as brass, bronze, zamak or stainless steel.
Unlike crude or homemade techniques, professional gold plating at FC Joias follows strict quality control protocols, using:
- 3 in-house laboratories with more than 90 state-of-the-art instruments
- Non-destructive XRF analysis to verify the authenticity of the gold applied
- Measurement in thousandths (g/kg per batch): the actual weight of metal deposited, not estimates
- A 100% in-house process with no outsourcing, ensuring full traceability
Why Gold Plating Outperforms Other Techniques
Unlike paint, foil or adhesive appliqués, electroplated gold plating creates a permanent molecular bond between the gold and the base metal. The result:
- Greater durability: Superior resistance to daily wear, sweat and friction
- Even finish: Complete coverage even on pieces with complex shapes
- Authentic shine: The same luster and tone as solid gold
- Hypoallergenic: Protection against oxidation and allergic reactions
How the Electroplating Process Works
Professional gold plating involves several technical stages carried out in a controlled environment:
1. Pretreatment and Cleaning
Before gold plating, each piece goes through:
- Ultrasonic degreasing to remove oils, residues and contaminants
- Chemical pickling that prepares the surface for perfect adhesion
- Ionic activation that creates ideal conditions for molecular deposition
2. Copper Plating (Adhesion Layer)
An intermediate layer of copper is applied that:
- Improves the adhesion of gold to the base metal
- Levels microscopic surface imperfections
- Acts as an additional anti-corrosion barrier
3. Nickel Plating (Protective Layer)
A semi-bright or bright nickel deposit that:
- Protects against oxidation and stains
- Increases surface hardness
- Prepares the base for a perfect gold luster
4. Applying the Gold Plating
The pieces are immersed in an electrolytic solution containing pure gold, where:
- Controlled electric current deposits gold atoms evenly
- Immersion time determines how many thousandths are applied
- Temperature and pH are monitored digitally in real time
- Standard samples validate quality without handling the customer's pieces
5. Finishing and Protection
After gold plating, the pieces receive:
- Cascade rinsing to remove solution residues
- Controlled drying that prevents stains and marks
- Optional Aldax varnish for additional nanotechnology protection

How to Gold-Plate Costume Jewelry and Semi-Jewelry
One of the most common questions is: can costume jewelry be gold-plated? The answer is yes, with some important technical caveats.
When Costume Jewelry Can Be Gold-Plated
FC Joias applies gold plating to costume jewelry and semi-jewelry that:
- Are made of conductive metals (brass, bronze, zamak, stainless steel)
- Are structurally sound, with no cracks or weak solder joints
- Have a suitable base finish without excessive porosity
- Do not contain stones that melt or lose color during chemical processing
Where to Gold-Plate Costume Jewelry
Gold-plating costume jewelry at home is technically impossible and dangerous. The professional process requires:
- Industrial electroplating equipment (tanks, rectifiers, filtration systems)
- Controlled chemicals (cyanides, acids, metal salts)
- Environmental and safety licenses (IBAMA, CETESB, Fire Department)
- Specialized technical know-how
FC Joias is located in Limeira, São Paulo state, Brazil's semi-jewelry capital, and serves customers throughout Brazil and abroad with:
Certified laboratories Structured logistics to receive and return batches A traceable, auditable process Advisory support before, during and after plating
Guaranteed Thousandths: The Only Reliable Standard
This is one of the most important things to know when hiring professional gold plating in Brazil.
What Thousandths Are (g/kg per Batch)
At FC Joias, all gold plating is measured in thousandths per batch, expressed in grams of gold per kilo of processed goods (g/kg).
How it works:
- 1 thousandth = 1 gram of gold applied for every kilo of pieces
- If your batch weighs 10 kg and you order 10 thousandths, 100 g of gold is applied in total
- If your batch weighs 5 kg and you order 8 thousandths, 40 g of gold is applied in total
Why We Measure in g/kg per Batch
Measuring by the total weight of metal deposited on the batch is the only reliable technical standard because it:
- Reflects actual consumption: You know exactly how much gold was applied
- Works for any shape: Rings, chains, earrings and complex pieces alike
- Is commercially fair: It allows transparent, auditable pricing
- Is traceable and verifiable: We control inputs and guarantee delivery
- Eliminates estimates: What you order is what we deliver
Typical Thousandth Levels
Depending on how your brand is positioned:
- 2-4 g/kg: Basic plating for occasional-wear costume jewelry
- 5-8 g/kg: Commercial standard for medium-turnover semi-jewelry
- 10-15 g/kg: Premium for brands that value durability
- 16+ g/kg: Top excellence for luxury collections
FC Joias Guaranteed Thousandths
When you order gold plating from FC Joias:
- The g/kg you order is exactly what we apply

How Much Gold Plating Costs
The investment in professional gold plating varies with:
Factors That Affect the Price
- Number of thousandths: More gold deposited means a higher cost
- Type of plating: Riviera, Quebec, Mont Blanc and Viena use different alloys

Frequently Asked Questions About Gold Plating
1. Can you gold-plate jewelry at home?
Not safely or with good quality. Professional gold plating requires industrial equipment (rectifiers, electrolytic tanks, filtration systems), controlled and hazardous chemicals (cyanides, concentrated acids) and specific environmental licenses. Home attempts produce very poor finishes, put your health at risk and can lead to legal liability for improper chemical disposal.
2. How does industrial gold plating work?
Industrial gold plating uses electroplating: pieces are immersed in an electrolytic solution containing gold ions. When a controlled electric current is applied, gold atoms deposit evenly on the metal surface, creating a permanent molecular bond. At FC Joias, this process is monitored digitally in real time, with control of temperature, pH, current density and immersion time to ensure consistent quality.
3. What is the difference between gold plating and gold-filled?
Gold plating is applied by electroplating (an electrochemical process that creates a molecular bond). Folheado, the traditional Brazilian term, once referred to thin sheets of gold pressed on mechanically. Today the terms are often used interchangeably in the Brazilian market, but technically electroplating delivers a better result in uniformity, adhesion and durability.
4. How do you remove gold plating from silver or other pieces?
Removing gold plating requires specific chemical processes (controlled acid stripping or reverse electrolysis) that should only be carried out by specialized companies. Never try to remove it at home: the products involved are dangerous, and the wrong process can irreversibly damage the base metal. FC Joias assesses feasibility and performs removal when technically possible.
5. Is gold plating real gold?
Yes. Gold plating uses pure gold (usually 24k) deposited on the surface of the piece. The difference from solid jewelry is that the gold is only in the outer layer (micrograms or milligrams), while in solid jewelry the entire volume is gold. But the material applied is genuine gold, and FC Joias verifies it with XRF analysis on every batch.
6. What is 18k gold plating?
Technically, 18k gold plating refers to applying a gold alloy that is 75% pure (18 parts gold out of 24). In practice, most commercial gold plating uses higher-purity gold (22k or 24k) to ensure adhesion and prevent stains. What creates the "18k look" is the addition of specific alloys that reproduce the traditional tone, as in our Quebec plating.
7. What is gold flash plating?
Gold flash plating is an ultra-thin application (usually 0.1 to 0.3 thousandths) used as an intermediate layer in multi-metal processes or as a very low-cost temporary finish. It is not recommended for finished products because it wears off in days or weeks. FC Joias does not offer flash as a final finish; our minimum standard ensures real durability.
8. Is gold plating expensive?
The investment in professional gold plating varies with the number of thousandths, the type of alloy, the batch volume and the complexity of the pieces. Compared with the added value it creates (differentiation, durability, a premium perception of quality), FC Joias gold plating offers excellent value for money. Customers report a 35-60% increase in average order value and up to 87% fewer returns, which makes the investment profitable quickly.
