New 9K Gold And 925 Sterling Silver Ring With Natural Ruby And Diamonds

Brand new handmade exotic ring with natural ruby and two natural diamonds. 925 sterling silver with a touch of 9 karat gold around the bezel set stones. Size between 4 and 4.25. Stamped Sterling, 9 CT (older mark for 9 K gold) and 375 (a European mark for 9 K gold). This ring came from an old collection of a jeweller and has never been worn. Will also make a great gift! The ruby is of a very pleasant pink- red color. I don't know anything about its origin and whether it was treated in any way (as many rubies are heat treated to enhance clarity and color).
