2LIPS Undecided Tourmaline stackable ring

What is this Tourmaline an undecided about? If it is Green or Red (or is it on its way to mix these colours (as in paint) in to shades of Brown, Khaki or Burgundy (that is what you get if you mix green and red paint). In a way you could call it a next generation Tourmaline since generation X does also not like to be placed in a defined category however since it is a gemstone by nature its state has been frozen in time. Where we humans age and change this beautiful gemstone will remain in its splendid state for ever. This 4 ct oval Tourmaline is set in our stackable 2LIPS ring (designed by the Dutch-designer and architect David-Aardewerk). 

The current ring size is 55/17,5, US size 7¼, UK size O½ resizing included.
