This is a large brooch with a crowned lion roaring on the left, and a fierce stallion standing to the right.  There is a crown in the center above the red, black and gold coat of arms.  There is a center stripe of red crosses and a vertical wavy stripe down the center.  The bottom says Le Droit and Semper Paratus.  There are two tiny pin holes on the bottom, I think so you can pin this to something substantial, like an army jacket.  It's very detailed.  The horse is not a unicorn.  The brooch measures 2 7/8 inches wide.
