14K Yellow Gold Green Stone Ring Possibly Green Tourmaline?

Yellow Gold Green Stone Ring. I think this says 14K but it was hard to read so I could be wrong. I also believe I was told these were green Tourmaline stones but I am not positive. I bought this new for myself a long time ago and never had it appraised so I’m not sure of the stones. I loved this and wore it a lot so it shows all over wear and has scratches, dents and other imperfections to the gold and to the stones. The size measurements on my ring size tool are approximate and just to help as a general guide as it didn’t sit well on the tool. I feel it’s between a 4 1/2 and a 5 but I may be wrong. Colors may be off because of lighting. This isn’t new and has been used so there are imperfections. Please ask questions.
