18K gold plated means that a piece has a coating made with 18-karat gold over a different base metal. Eighteen-karat gold is 75% gold within the coating. The base metal, coating process and layer thickness are separate specifications.
What the 18K label tells you
Karat measures gold purity on a 24-part scale. In the phrase “18K gold plated,” the 18K label applies to the gold used for the outer coating. A complete product page should also identify the base metal when that information is confirmed.
“PL 18K” and “18K GP” are common abbreviations for 18K gold plated. Read the full phrase rather than relying on the number alone.
What the label does not specify
The phrase does not, by itself, state the coating thickness, application process or expected lifespan. Those details depend on the construction of the selected piece and how it is worn and cared for.
The FTC consumer guide to jewelry explains that gold plating can be applied by different processes and that the surface eventually wears according to thickness and use.
What to check before buying
- The exact base metal named in the listing
- The stated plating or coating
- The pendant size, weight and chain length
- The care instructions for that item
A close-up photo helps you evaluate design and finish, but the written product specification is the source for material details.
How to care for a plated finish
Keep the piece away from water, perfume, lotions and cleaning products. Remove it before bathing or swimming, wipe it with a soft dry cloth after wear and store it separately.
How LUPE ORO labels each piece
