Stripes & Blades by Daniel Starr

Note: Dan was kind enough to give his “Stripes & Blades” design to the faceting community. I am sure he would be glad to hear from anybody that cuts his design. Some of you may notice some similarity to my Mirage designs. Dan cut some of them and liked them and was inspired to create his “Stripes & Blades” design.
Thanks for the design Dan…. Jeff

Ametrine  by Daniel Starr

Daniel Starr – Cutting Remarks

The stone was cut from Ametrine (supplied by Gram Faceting), it weighs 5.06 carats, measures 11.1mm wide x 7.5mm deep.

I’ve been puttering around trying to learn GemCad. I couldn’t sleep one night and Jeff’s advice to me to “Think outside the box!” kept ringing in my mind.

How could I make a square (or mostly square) design that hadn’t already been done? And how to make it easy to cut? Well….here’s my first solution. It’s a bit unusual, but I hope you all enjoy it!

This is an easy design to cut as long as you can get the crown spiral set correctly. Any error in the spiral may be magnified when cutting the stripes (or chevrons). The stripes should be cut the same way you cut C-1 and C-2 to establish the girdle. Also, the stripes almost require that the stone be fairly large or else they may tend to become too thin. The table should be cut and polished before C-10. Then C-10 can be polished to meet the table corners. Be careful about trying to lengthen your finished C-10 facets: if you adjust C-10 much above 18 degrees, you could adversely affect the brightness of the stone.
