All my pipes get a grading (diamonds). My decision on grading is based on the quality of the wood, harmony and overall impression.
The definition of the class I decide based on wood quality, harmony and overall impression.
I use for great quality pipes the higher classification with diamonds..
The combination of my name with one to five diamonds reflect the quality of the wood, the technical skill and the attractive shape of the pipe.
Pipes with 5 diamonds or also with a crown are very rare, but perfect.
