Technical Observations: The surface is white metal with areas of green and red. Some areas are deeply mineralized. The clean metallic surfaces, the lack of a layer of green corrosion, and the survival of lumps of red, probably cuprite, may indicate that the object was cleaned electrolytically, which removed any green corrosion. The bright green corrosion products on the back look more superficial and recent, and these could be the result of residues acting on the surface after this treatment.
The flat star-shape and the projecting conical section were cast as a single piece. The wax model for this component may have been shaped indirectly using a mold. The beaded bands, decorative balls, and pin components all appear to be soldered in place with a hard solder. The silver color of the surfaces, including some on the back, is probably the result of a wash of silver over the copper alloy substrate. The slightly reddish tint in some areas could be the copper alloy surface emerging through the wash. Two wire loop fasteners are soldered to two of the projecting point, and a portion of an attachment wire is trapped in one of them. The beaded bands appear to be strips of wire pressed into a form or other device to create the appearance of small beads. Two of the large circular strips surrounding the conical section are straight wires with no beading.
