Technical Details: The design outline is engraved on the front of the .010 thick platinum clad niobium and the platinum removed. then outlined with a chisel-like tool. the resulting raised outline is then raised (repoussse) from the back. After diamond filing, the piece is heat treated to create the black oxide which is very tough. The gold was simply soldered to some platinum left for that purpose. After capture in the Argentium frame it measures .050 thick. Anodized colors were added before mounting in frame.
