This is described as a “mud” emerald ring … not sure if that is referring to the clarity of the stone, its colour or, well, just not sure. I really like the multi-tourmaline band.

This is a one of a kind ring, available in size 7 and my guess from the photo is that it is not sizeable, given the eternity setting. Available from Covet NYC for USD $3165; you can purchase it here.
