RARE D'ORLAN BOUCHER 4" peacock paradise bird rhinestone crystal brooch

Signed D'Orlan....This is the first time I see this model of D'Orlan brooch..... And I didn't find it anywhere on the net... The large stones are black....There is no shortage of stones, but some are yellowed.... There are several oxidation points on the plating of the bird's body, and there is a small spot where the plating is missing on the bird's crown....It measure 4" x 1 3/4".....
