This is a unique pipe. A half-Blast/Half-Smooth Demi-Egg Sitter. As you can see from the photos, one half of the pipe is contrast dyed and finished smooth while the other side has a beautiful ring grain blast. The briar block's plateau was conserved and fills the entire heel such that the pipe is easily balanced to sit. 
The stem is polished black ebonite.
