PrinceCut Diamond
June 09, 2005
Anne and I attended the JCK Fine Jewelry Trade Show in Las Vegas last weekend and were able to see the PrinceCut diamond which is a patented modified emerald shaped diamonds that was beautiful. It has 111 facets compared to the typical emerald that has 46 facets so had much more brilliance and fire (scintillation).

The issuing of patents with no reference to prior art would be amusing if it wasnt dangerous!
The "Prince Cut" is a bastard union of a scissor cut crown with a "Princess" style pavillion.
The obvious alteration to this would be to split the four main facets to produce 115 facets and then calling it a "king" or some such.
A german company was selling Amethyst with a cut that looks identical in the 1970's .
Also by the logic of granting patents on
fitting random cuts together, and ignoring prior art I would like to patent a new cut the "Clog" it is a stone with a "Dutch Rose " as crown and paillion, its ugly; but then I sue all cutters for using my patented triangular facets.
A truly novel style of cutting should be protected but using the patent system purely as a marketing ploy to monopolise a name , and a name cynically chosen to build on the "Princess Cut" an ownerless brand does show a certain low cunning , as contesting it would cost too much .
I suggest that all cutters copyright any cuts they like and call them after the illegitimate male offspring of European nobility of the last 1000 years , thus the "Prince Edward" cut a modified scissor cut with 115 facets has today been registered with my Lawyer ,copyright is so much faster than patents.
