This piece features a bowl and foot sections of Mazanita and the stem is turned from Maple. This guy sold a while back, but to the best of my recollection, the bowl section was 4" in diameter and walls about 1/8  thick. The overall height of the piece was about 11".
 
If you would like a wine glass similar to this one, please contact me so we can discuss a time line for getting one made.
