Why are costume jewelry pieces plated with 18k gold and not 24k gold?
Have you ever wondered why most costume jewelry is plated with 18k gold and not 24k gold? You're not alone. Many people believe that the "purer" the gold, the better the piece. But in reality, that's not quite the case. Today we'll explain, in simple terms, why 18k gold costume jewelry is preferred in Portugal and Europe – and why it makes all the difference in your daily life.
What does 24k gold mean?
24k gold is gold in its purest form – virtually unmixed with other metals. It is considered the most valuable, but also the softest and most brittle. This means that if it were used directly in costume jewelry, it could:
-
Scratch easily
-
Deforms with daily use.
-
Losing its shine quickly
In other words, despite being very pure, it's not the most practical for items we use every day.

Why use 18k gold in costume jewelry?
18k gold is a mixture of 75% pure gold and 25% other metals (such as copper, silver, or palladium). This combination provides the perfect balance between beauty and durability.
When plated with 18k gold, the costume jewelry acquires a sophisticated finish and at the same time:
✨ More resistant to scratches and deformation
✨ With a color and shine very similar to solid gold.
✨ Best value for money

-
24k gold : has a more intense yellow tone, which doesn't always appeal to European tastes, where a more discreet gold is preferred.
