Green Tourmaline Silver Ring, Deep Forest Wood Grain - Rugged tree limbs wrap around the finger in this unique ring. It is wide and sturdy, appx 9mm. The branches and limbs stand up to grasp a green tourmaline with surprising depth of color. Deep green, nearly black under some lighting, but with an internal flash of fire that draws the eye. The stone is an elongated cushion cut, one of a kind cut. Therefore, we simply had to create a one of a kind setting. Sterling silver.
