As a huge Seattle Seahawks fan, I was thrilled to find this in my back yard last summer...actually stumbled over it...just popped up out of the ground after a rain.  I couldn't believe that it looked just like the Seahawks logo.  It's a real, natural stone.
Even though I want to keep it, I could use the funds of it's sale (to a diehard fan) to pay off a medical bill from an accident last year.  It would look really cool either on a shelf behind glass, or even in it's own little glass cube.  Small (about 1-3/4" long), so it would fit in well amongst other Seahawks memorabilia.  It is natural, and kind of a tan/bronze color, even though the pictures may show it of a slightly different shade (a little greener?).  It's truly one-of-a-kind!
Thanks for looking.
