blue tourmaline butterfly 🦋 ring

I have to admit that I thought it is blue. But after look at it for several minutes. I feel it is greenish blue, more like teal, not Tiffany blue. This is more blue in darker lights. It changes color to more green when light is stronger! Butterfly 🦋 greenish blue tourmaline ring Very unique and light in color Adjustable ring Size 6.5 - 7
