The form of these bracelets is the inspiration for the ribbed cuffs that I have been making and posting here. The "H" shaped form is made from a pair of cast segmented pieces connected with a thin infill panel. The shape is tapered with one end about 5/8" wider than the other.
The other end is a kind of offset or expanded replication of the main pattern on the infill panel. The casting has a dark void space between the outer edge and the inner edge that is soldered to the infill panel. The material is a hard mixed metal brass of unknown composition.
The patterns are a repeating series of diamonds. circles, and linear shapes that resemble a textile fabric. The interior is smooth although this pair seems to have a lot of wear and some separation of the metal at the seams.
