The deep yellow green color caught my eye as this little bugger sat on a shelf down in my basement. When I brought it out into the daylight I could see what I used to call amber swirls. They are swirls but these Icon discussions have left me shell shocked. What ever color they are, the overall effect is a beautiful yellow green color. On the upper ridge of the wire groove, to the left of the embossing, there is a narrow open bubble with just a touch of a chip at one end. It`s something you feel it more than you than you see it. $25 shipped to your door.
