- Older brooches usually have smooth backs, not patterned ones.
- Copyright symbols appear on jewelry made from about 1955 on, not before.
- Aurora borealis rhinestones did not appear until the mid 50's.
- Quality vintage rhinestone pieces are usually prong-set.
- Authentic vintage jewelry should show minor signs of wear, particularly in the clasp area. But maybe not if it was stashed away in some one's jewelry box.
- An older piece, more often than not, will have significant weight.

Estate Jewelry - second hand, garage sale, auction, high-end, Contemporary-era, not very old.
Vintage Jewelry - 20 to 30 years old, 1980's and earlier
eras - Modern, Mid Century Modern, Retro, Art Deco.
Antique Jewelry - 100 years old or older, 1920's are now considered antique.
eras - Art Deco, Edwardian, Art Nouveau, Victorian, Georgian and earlier.
A lot of descriptions of jewelry will list, for example, a piece as Art Deco style. Don't let this confuse you into thinking this is an older piece. They are talking about the "style" being copied from the era. In other words it looks like an actual Art Deco piece but it's not. This is done with all types of jewelry and any era.
