Vintage Gold Tone Sterling Silver Faux Diamond / Ruby Cheetah Ring

this is a vintage gold tone sterling silver ring in the shape of a cheetah. I Believe the stones are faux, but I haven't tested. this ring is vintage and has some wear and tarnish but I'm sure it would look great after being polished. The ring is size 6.5. signed on the inside 925 as well as what looks like FK. measures approximately a half an inch wide at the head and arms.
