Tension Bracelet with Smith Bar Tourmaline
This photo, taken for a show at the Tucson Art Museum, doesn't do the stone a lot of justice. The flawless, medium forest-green tourmaline has some blue overtones you can't see here. The Smith Bar-cut stone is tension mounted in a white gold bracelet by third generation jewelry artisan Sam Patania.
A curator from the Smithsonian Institution saw the piece at the show and spoke with Mr. Patania about submitting it (and two other pieces by his father and grandfather) to the museum. It's now on display at the Renwick Gallery.
Cutting Remarks
The Smith Bar cuts in quartz with no changes. Notice the lowest angle on the pavilion is 41°. It can have almost any length to width ratio (L/W) with no changes. It also works well in tourmaline that's dark or closed on the c-axis. You can cut the corners in or leave them pointed.
Enjoy cutting your own Smith Bar.
