This unique piece is reticulated / has open work on the top. The sides and underside are solid sterling. It is marked sterling. I note no manufacturer markings; due to it's uniqueness, I would have expected to see Danecraft or Beau. The bracelet is 3/8" wide and 2 1/2" inside diameter. It is a very sturdy piece and would not easily bend (that is one of the great attributes of vintage sterling). It has one area with some denting, inside and outside. It needs further cleaning.
