The difference between jewelry that stays beautiful
and jewelry that quickly discolors often lies not in the design.
It lies in the plating.
Many pieces of jewelry look the same at first:
- the same color
- the same shine
- the same appearance
But over time, you only see the real difference.
One stays beautiful.
The other becomes dull, lighter, or uneven in color.
This is due to the way the gold layer is applied.
What exactly is plating?
Most gold jewelry is not solid gold.
It consists of:
- a base material (such as stainless steel)
- with a layer of gold over it
We call that gold layer plating.
But not all plating is the same—and that determines how long a piece of jewelry stays beautiful.
The different types of plating (and their differences)
Below you can see the most commonly used techniques for jewelry:
| Plating type | How it is applied | Durability | Color retention | Lifespan |
|---|---|---|---|---|
| Flash plating | Very thin layer of gold, applied quickly | Very low | Fades quickly | A few weeks to months |
| Electroplating (standard) | Gold is applied via electricity | Average | Fair | A few months |
| Ion plating | Improved adhesion via ionization | Good | More stable | 1–2 years |
| PVD plating | Molecular adhesion (vacuum technique) | Very high | Stays beautiful for a long time | Multiple years |
Why some jewelry discolors so quickly
Many cheaper pieces of jewelry use flash plating.
That is:
- fast
- cheap
- and looks good at first glance
But:
- the layer is extremely thin
- wears out quickly through use
- and quickly loses its color
This type of jewelry is often not made to be worn for a long time.
Why 'thicker' is not always better for stainless steel
A commonly heard claim is:
“The thicker the gold layer (microns), the better.”
That is partly true—but not for every material.
With stainless steel, it works differently.
It is less about extreme thickness,
and more about:
- adhesion
- flexibility of the layer
- and surface preparation
A layer that is too thick can even:
- move less well
- crack more easily
- and therefore wear out faster
That is why you rarely see truly thick layers on stainless steel, like you do with silver or brass.
Why you sometimes see claims that do not make sense
Some brands mention high micron values, such as:
- “5 micron gold”
- “6 micron plating”
That may be true for certain materials.
But on stainless steel, that is often not realistic or functional.
This is because the focus is on:
- technology
- adhesion
- and layer buildup
Not on extreme thickness alone.
What then does determine whether jewelry stays beautiful?
The quality of plating depends on several factors:
- how well the surface is prepared
- how evenly the layer is applied
- how strong the adhesion is
- and how stable the color buildup is
That is why two pieces of jewelry that look the same
can behave completely differently after wearing.
