Vermeil pieces are a great alternative to solid gold pieces. The base is solid 925 Sterling Silver with a thick coat of 18K Gold.
The shade of gold is the exact same as a Solid 14K Gold piece. If you have the budget, Vermeil is the way to go.
If you're ordering a Vermeil Pendant, the chain will also be made with 925 Sterling Silver. These pieces are stamped with '925'.
