18k gold vermeil refers to a specific type of gold jewelry that is made using a layer of gold over a base metal, typically sterling silver. Here’s a breakdown of the terms:
18k Gold: The “18k” indicates the purity of the gold used in the vermeil. Pure gold is 24 karats, so 18k gold is 75% gold and 25% other metals (such as copper, silver, or palladium) that are alloyed with the gold to give it strength and alter its color.
Vermeil: This term specifically refers to a process where a thin layer of gold is electroplated onto a base metal. For a piece to be classified as vermeil, it must meet certain criteria:
- The base metal must be sterling silver (at least 92.5% silver).
- The gold layer must be at least 2.5 microns thick.
The gold used must be of at least 10k purity.
Characteristics: Jewelry made from 18k gold vermeil has the appearance of solid gold but is more affordable due to the silver base. It also has a warm, rich color because of the high gold content. However, since it is not solid gold, it may tarnish or wear off over time, especially with exposure to moisture, chemicals, or abrasion.
Care: To maintain the appearance of 18k gold vermeil, it’s recommended to avoid harsh chemicals, take off the jewelry before swimming or showering, and store it in a dry place away from direct sunlight.
In summary, 18k gold vermeil is a popular choice for jewelry enthusiasts looking for the luxurious look of gold at a more accessible price point, while still enjoying the benefits of sterling silver as a base metal.
