For your consideration is this nice signed "1/20 12K GF Sturdy" bracelet. Sturdy started making jewelry in the 1800s. This is circa 1920 with an older slide clasp. It has a nice Art Deco geometric look with blue diamond cut glass stones.
The bracelet measures 7 and 1/4 inches when clasped. It is a hair under 1/2 inch top of bottom at stones.
It is in excellent functioning condition.
