Well, I don't know what kind of butterfly this is exactly, but what I do know is that it is gorgeous, and that it is from EARLY in Jesse's career, and it also has to be VERY rare, because I've never seen another marble with this butterfly on it. It is in Jesse's famous and classic style, with the featured murrine, a ring of flowers, and a twist on the bottom - in this case, a light green twist made from the legendary OG Moss glass. This is a serious collector's piece. It was made in 2001 and signed 'Taj 2001'.
