I am looking at this mint tourmaline from a vendor that I have seen recommended here. It is 1.09 carats, 6mm and vvs with no treatments, the rough is from Nigeria. It is priced at $350. What I am looking for is a cool refreshing gem that is green with a bit of a blue modifier and no yellow, I also want a precision cut which this is. What do you all think of this tourmaline? The first photo is in a studio and the second is in indirect sunlight.
