Durability is all about the karat and the coverage.
The greater the karat the more durable the piece. 24 karat gold is “nguyên chất” vàng. But pure here doesn’t mean it’s only gold when turned into a piece of jewelry.
Vàng is a soft metal.
Vì thế, in jewelry, which requires a certain amount of durability, alloys are often used. An alloy is a metal that is combined with gold to increase durability.
Like all gold jewelry, vermeil follows suit. If you are looking for the most durable kind of jewelry, you’ll look for 24 karat gold plating on the piece, but even 10 karat vermeil is better quality than other gold-plated alternatives.
Thickness is also important. The thicker the plating, the longer it will last.
You will want to look for the quality of the core alloy. Vermeil makes this easy for you. As genuine vermeil will always have a core alloy of sterling silver.
If there is a base metal over the sterling silver, it must be disclosed per U.S. quy định.
Micron plating is what it is all about.
This is the thickness of the gold. Micron plating at minimum is 1 Micron, where it becomes measurable. But for this type of jewelry, the required minimum is 2.5.
