The vermeil jewels are made of silver covered with 5 microns of gold.
The gold-plated ones are made of brass covered with copper and then with 3 microns of gold.
And fine plated jewelry is of lower quality than gold-plated because it is plated with 1 micron of gold.
Vermeil jewels are more precious than gold-plated ones because their base is made of 925 silver and not of brass.
They are heavier than gold-plated jewelry.
Vermeil jewelry is very resistant to oxidation and rust.
They do not produce allergies because both metals are hypoallergenic.
They are much more sustainable and ethical.
