Antique vs. Vintage Jewelry

Here is a question for you? What is the difference between Antique & Vintage Jewelry?

It's pretty simple: Antiques are objects that were manufactured at an earlier period and according to several laws at least a century old. 

If antiques are items that are a century old or older, what do we consider Vintage? The term โ€œVintageโ€ is primarily related to wine and takes its origin in the old the French word โ€˜โ€™Vendangeโ€™โ€™, that means โ€˜โ€™the grape harvest during a seasonโ€™โ€™.
One of its secondary but most common definitions is a period of manufacture (by example, a vintage 1970s Cartier Ring).
Vintage should not be used for items less than 20 years old.
