Love this pattern.  This is not my pattern I got this from I believe it was Delphi a few years back.  I have seen others like it online and they are all so beautiful so I thought I would share this pattern with everyone!  Adding the wire work takes this piece to the next level!  
I recommend a hammered glass.  What makes this piece more advanced is the curves in the glass and getting them to line up correctly which is why I recommend it for intermediate level.
 
This piece pictured is a gift for a dear family member who I'm sure is going to love it!!!
