This eyeball marble needs and LOVES the light, it really responds to it and looks great against a darker background. Super fun to study the fuming inside, so many twists and turns! From John: "This one is similar to The Fragile Pulse but much more tamed/translucent. It reminds me vividly of the look in my 90-year old grandmother's eye, a milky reflective quality that shows transition is near; it's an eye that looks from the threshold of the veil."
