This tremendous beauty is from Geoff's air trap series of marbles, where each air trap creation represents a bird in a cage. Transparent glass is woven incredibly elegantly inside of crystal clear glass, giving us a magical result that truly looooves the light! Sooooooo much sweeter in hand than these pictures show! I shouldn't have even taken those pics on a black background, those came out terrible, and don't show the marble at all what it looks like in hand. The inner 'bird' air trap is a wonderful transparent blue, but it came out too dark in those black pics. Signed 'G Beetem P.2003' - I believe the P stands for premium, but I'm not positive.
