Vintage Sterling Silver Pendant - Winged Unicorn

Dating to the 1990s or so, here's a Sterling Silver (hallmarked as pictured) pendant. In a round shape, the inside bears the design of a winged unicorn. Size is 1-1/8" wide/high not including the top bale; weight is 5.2 grams. Lovely condition with a makers mark to the reverse that I do not recognize. All that's needed now is the right chain - mine is for display purposes only.
