Victorian Belt Buckle Half Black Material Brass Back

Unsigned, as pictured half a Victorian era belt buck with brass piece on back. Not sure what the black material us, under 10x looks like Bois Durci, but I cannot say with certainty. Great if you have the other half, otherwise repurpose into a antique brooch :) Please review all of the photographs as they are of the actual item you are buying.
