1920's & 1930's Costume Jewelry Earrings

I have a small hoard of costume jewelry that belonged to my mother (born in 1921) and my "Me Ma" (born in 1897). Most consists of earrings, but there are pins/broaches, necklaces & bracelets as well. This is just a few of the ones I like. The pair of red bead earrings are from the early 1900's and may have originated with my great grandmother. They are German. The green ones are old but not as old as the red ones. The large ones are ones I saw my mother wear many times growing up in the 50's & 60's. The ones in pic 2 & 3 are a few others that always use to catch my attention worn by those two ladies in my life. They are also from a group that are early to mid 20th century.
