Note: Dan was kind enough to give his "Hammers" design to the faceting community. I am sure he would be glad to hear from anybody that cuts his design. Thanks for the design Dan.... Jeff

Daniel Starr - Cutting Remarks
The stone was cut from Ametthyst (supplied by Gram Faceting), it weighs 2.56 carats, measures 8.5mm wide x 5.6mm deep.
Here's an easy one to cut! The pavilion is quite basic...all the fun comes in the crown.I purposely tried to make another Mirage design when I designed this one. But it also had to be easy to cut. I think this design is both.
Once again, there is a "second girdle" running around the crown. Cut C4 and C5 just as you would the facets that establish the girdle: Just go round and round. Better have the spiral set correctly. The long sides of 96-24-48-72 give off a nice flash in person. Polishing C6 to meet C1 goes very quickly, so be extra careful there. The table should be completed before working on C7. C7 can be adjusted no higher than 14 degrees, but can be taken down to 11 degrees if you like. Decreasing C7 towards 11 degrees steadily increases the brightness of the stone, but not by too much. My wife immediately appropriated the finished amethyst, which looks better in person.
