Black Onyx Sterling Silver Earrings, Oval Pin and Ring

Vintage, large, oval sterling silver stud earrings with black onyx, oval black onyx vintage sterling silver pin brooch and a black onyx sterling silver ring to finish the set off. I did not purchase these together, but always wore them together because they looked striking together as a set. Especially when I was wearing all black! Hallmark stamp FB on pin (4.5cm wide) MG sterling on the earrings(3.5cm long) and 925 on the inside of the ring (about 2cm at widest part). Ring size 7. I haven't worn this jewelry in years and would love for someone else to enjoy them.
