There is a thread on this topic at a not very popular chat site.

People have said that the Royal Asscher has a patented facet arrangement.
I was of the opinion that the original patent from 100 years ago was now defunct and anyone can cut that stone.
The name Asscher too has drifted around and has no trade mark anymore - which is why the orginators grandchildren called the stone ROYAL Asscher.

Any of you IP geeks out there care to advise us?
