Guaranteed Thousandths

Do you know whether you are really getting the thousandths you paid for?

In the world of electroplating and semi-jewelry plating, one of the most talked-about and least understood terms is “thousandths.” Anyone who has ordered gold plating has faced the question: “How many thousandths do you want applied to your lot?”

But this raises the question that really matters:

Did the lot receive exactly the thousandths you ordered, or just an approximation?

This question is essential because it determines three critical points for your business:

• The real cost of your collection: every thousandth represents an investment in precious metal.
• The durability and shine of the pieces: thousandths are decisive for the service life of the pieces.
• Your brand's reputation: when durability fails, the impact on after-sales is immediate.

Why does this question matter so much?

In the semi-jewelry market, trust between the buyer and the plating provider has to be absolute. End customers do not know how to calculate thousandths; they judge quality by simple things: shine, resistance and durability.

If the thousandths applied fall short of what was ordered, the result is clear:

• The piece loses its shine faster.
• Wear shows up sooner than expected.
• The end consumer's experience suffers.

And when that happens, your brand takes the hit, not the supplier that did the plating.

That is why the question that opens this article is not just technical; it is strategic for the health of your business:

How can you be sure that the thousandths ordered per lot were actually applied when your semi-jewelry was plated?

So what are thousandths in semi-jewelry plating?

When we talk about thousandths applied in gold plating, we mean a unit of weight used in Brazil to quantify the amount of precious metal applied during the electroplating process.

Here is how it works:

• 1 thousandth equals 1 gram of gold applied for every kilogram of pieces processed.
• In other words, if a lot of semi-jewelry weighs 10 kg and you order 10 thousandths, a total of 100 g of gold will be applied.

This measure is practical, recognized across the market and has a direct impact on the durability, shine and resistance of the pieces.

Why do we use thousandths per lot (g/kg) instead of thickness in microns?

Many people assume plating is measured only by the thickness of the metal layer. In practice, however, deposition is not uniform: edges, flat surfaces and fine details receive different amounts of metal.

If we only looked at “thickness at one specific point,” we would risk getting a partial and misleading reading.

By using thousandths per lot (g/kg), we guarantee a fairer and more transparent yardstick, because it:

• Reflects the actual weight of metal consumed during the process.
• Applies to the entire lot, regardless of the shape of the pieces.
• Gives customers a clear forecast of the investment in each production run.

Bottom line: the per-lot model is the most reliable way to order plating, because it links cost and result in a practical, auditable way.

How to interpret thousandths in your order

Think of thousandths as a “protective load” applied to the lot.

• Low thousandths (up to 2 g/kg): used for basic plating, usually on costume jewelry or pieces with a short service life.
• Intermediate levels (3 to 7 g/kg): a balance between cost and durability, ideal for fast-moving semi-jewelry collections.
• Higher levels (8 to 20 g/kg): top quality, intense shine and maximum resistance to daily wear.

Important: the right level depends on your brand's positioning and the market you serve. A premium brand, for example, tends to work with higher levels to build loyalty among end consumers.

The direct impact of thousandths on your business

The thousandths applied are not just a technical detail; they directly influence:

1. The perceived value of the piece

   • More thousandths = more shine and sophistication.
   • End customers can see and feel the difference.

2. Durability and resistance

   • Higher thousandths provide protection against wear and oxidation.
   • They prevent returns and after-sales complaints.

3. Brand reputation

   • Pieces that stay beautiful longer inspire trust.
   • This directly drives repeat purchases and loyalty.

4. The real cost of the collection

   • Every thousandth ordered represents an investment in precious metal.
   • Working with predictability avoids surprises when you price your pieces.

Guaranteed thousandths: transparency that makes a difference

One of the biggest worries for anyone ordering semi-jewelry plating is this: Am I getting all the thousandths I paid for?

The concern is understandable, because applying precious metals involves significant sums and has a direct impact on the final result.

At FC Joias, this is the very core of what we offer: when we say guaranteed thousandths, we mean that what you ordered is exactly what we deliver.

And we do it based on:

• Rigorous input controls: nothing enters the process without being checked.
• Plating bath calibration: we ensure stability before processing the lot.
• Validation on standard samples: we protect your pieces and ensure predictability.
• A 100% in-house process: full control from start to finish.

What you will learn next

Now that you understand what thousandths are, how to interpret the most common levels and why the per-lot model is fairer, let's move on to the practical side:

How FC Joias ensures that the thousandths you order are actually applied to your lot, lot after lot, with no room for doubt.

Controls that start before plating

At FC Joias, guaranteeing thousandths does not start in the plating tank. The process begins earlier, when inputs are received and solutions are prepared.

1. Input verification (XRF)

   • All precious metal that arrives at our plant is analyzed by X-ray fluorescence (XRF).
   • This test confirms the exact composition of the inputs without destroying the material.
   • It ensures that the gold applied matches what you ordered.

2. Supplier control

   • We work only with approved suppliers, which reduces the risk of variation in raw materials.
   • This ensures consistency, lot after lot.

Solution preparation and calibration

The plating solution is like the “recipe” that applies the thousandths to your lot. And like any good recipe, it has to be balanced.

• Fine chemical adjustments: we measure and adjust concentration, pH, conductivity and temperature.
• Hull cell: this test simulates how the solution behaves and ensures the plating will deposit in a stable and predictable way.
• Internal checklists: every step is recorded, creating traceability and transparency.

The result is simple: when the lot enters the line, we already know the plating bath is calibrated to deliver exactly the thousandths ordered.

Validation on standard samples (no risk to your pieces)

A common question is: “Do you measure directly on my pieces?” The answer is clear: no.

• Instead of exposing your pieces to destructive testing, we use standard samples.
• These samples are processed together with the lot and then measured and tested.
• This keeps quality control rigorous without putting your product at risk.

This practice protects your merchandise and ensures predictable results.

Production under locked parameters

When it is time to run the plating, nothing is left to chance:

• Defined parameters: current density, time, agitation and temperature are set according to the validated process route.
• A trained team: our professionals are trained to follow standardized procedures, avoiding operational variation.
• A 100% in-house process: we do not outsource critical steps, which ensures full control from start to finish.

This means every lot follows a validated “production script,” with consistency and repeatability.

Continuous monitoring during plating

While the lot is being processed, the parameters are tracked in real time.

• Digital pH: kept within the ideal range for stable deposition.
• Controlled temperature: ensures efficiency and uniformity.
• Electrical conductivity: monitors the solution's concentration to prevent deviations.
• ICP/AAS (when applicable): laboratory analyses that confirm the chemical composition.

Together, these controls make it possible to spot and correct any deviation before it affects the lot.

Tests that prove quality

After plating, validation testing comes into play:

1. Measuring thousandths on standard samples

   • We confirm that the weight of metal applied matches what was ordered.

2. Hardness testing (nanoindentation)

   • Measures the mechanical strength of the layer.
   • Ensures the plating is not just beautiful but also durable.

3. Visual and functional inspection

   • Shine, uniformity and adhesion are evaluated by specialized professionals.
   • We complement technical measurement with aesthetic analysis.

Functional, hypoallergenic layer design

Beyond the thousandths ordered, many customers also want the piece to be safe for the person wearing it.

• Insulating intermediate layer: applied to keep reactive metals (such as nickel) from coming into contact with the skin.
• Gold, rhodium or silver top plating: provides shine, durability and comfort.
• Varnishes and topcoats (when applied): increase resistance to scratches and tarnishing.

This extra care is part of our commitment to delivering pieces that are not only beautiful but also safe and comfortable for everyday wear.

Lot traceability: end-to-end confidence

One of FC Joias' great differentiators is that every lot has its own recorded history.

• Every step is documented, from the arrival of inputs to final finishing.
• This means we can trace and prove how the plating was carried out.
• For customers, this translates into confidence and predictability: you know your lot was handled with technical rigor.

The result: guaranteed thousandths, no room for doubt

In practice, this entire system of controls, tests and records adds up to a single commitment:

The thousandths you ordered are exactly what will be delivered on your lot.

These are not vague promises but a solid process, developed and refined over nearly 25 years.

And that is what sets FC Joias apart in the market:

• We do not just sell plating; we sell security and predictability.
• We deliver lots that uphold the value of your brand.
• We make sure you never get shortchanged, and receive real, proven and consistent quality instead.

FAQ: Guaranteed thousandths in semi-jewelry plating

1. What does ordering 10 thousandths per lot mean? It means that for every kilogram of pieces processed, 10 grams of gold will be applied. If the lot weighs 12 kg, the commitment is 120 g in total.

2. Do you measure directly on the customer's pieces? No. To protect your merchandise, we use standard samples for quality control. This way, we validate the process with no risk of damaging your pieces.

3. How can I be sure I received what I ordered? Because we have a rigorous control workflow that includes:

• Input verification,
• Plating bath calibration,
• Testing on standard samples,
• Continuous parameter monitoring,
• Internal records for each lot.

4. If my lot has very different pieces (small, large, hollow), does that affect the thousandths? No. Since the yardstick is measured in g/kg, the commitment applies to the lot as a whole. That gives you predictability even with mixed collections.

5. Can I specify hypoallergenic plating along with the thousandths? Yes. Many customers choose hypoallergenic layers, which isolate reactive metals and make the piece more comfortable to wear. You can request this when you place your order.

6. Is your process outsourced? No. Everything happens inside FC Joias. That is how we ensure traceability and consistency.

7. What if there is some variation? Our quality system detects any inconsistency and applies an immediate correction. The goal is for the lot to leave exactly within the standard you ordered.

Practical checklist before ordering semi-jewelry plating

To avoid surprises, use this checklist every time you order plating:

Define the level of thousandths (g/kg) that makes sense for your collection. State the lot weight (kg) clearly in your order. Choose the finish (Riviera, Quebec, Mont Blanc or Viena gold; rhodium; silver). Confirm special requirements (e.g., hypoallergenic plating, protective varnish). Check whether the process is in-house (no outsourcing). Ask about input controls (how the gold and rhodium are verified). Understand the validation model (whether they test on standard samples or on your pieces). Confirm production and delivery lead times. Flag sensitive piece types (such as large hoops or articulated pieces) to set the right level of thousandths. Ask for predictability: confirm that what you order is what you get, with no room for doubt.

In short

Guaranteed thousandths are more than a technical measure: they are the difference between collections that delight end customers and collections that cause headaches.

When you choose FC Joias, you can be sure that:

• The plating applied to your lot follows the agreement exactly,
• Your brand delivers consistent durability and shine,
• You have the predictability and confidence to scale your business.

That is what working with truly guaranteed thousandths means.
