This is a very nice length of handmade beadwork trim from the 1930s. The piece is made of milk glass beads in 3 sizes and shapes; the large drops measure 7mm. It is 12 1/4" (31 cm) long and would be a striking embellishment for the round or scooped neckline of a dark colored, particularly black, dress. It could also trim a hat or bridal headpiece.
Because of its age, I would not recommend trying to wear it as a necklace, but it should be perfectly o.k. if hand sewn to a dry clean only garment.
