Dating to the 1930s or so, may I offer this Art Deco era pendant piece - jewelry finding that I believe originated in Czechoslovakia.  The drop is made of a brass colored base metal and highlighted with dark blue glass pastes (glass) - 1 large center oval and 4 small rounds.  Two rings at the top left and right for adding a chain.  Light surface marks to the top that show in my photos but do not show when holding the piece in your hand. 

Size is 1-15/16" wide x 1-3/8" high. 

Condition is very nice with just a bit of solder residue on the reverse - the piece might have originally been a pin.  Very nice and ready to be made in a bigger piece of jewelry!
