Both pieces are constructed of wrapped gold-tone wire and than twisted to form an interesting design.  
The bracelet has smaller wire twists than the brooch creating a delicate look.  
The brooch also has a small open area which maybe a defect or was done on purpose as a wrap around the center circle.  
The bracelet measures 7 inches long and has a crab claw closure.  The brooch is 1-1/4 inches in diameter and has a strong safety clip on the back.
