You can find cutting instructions for Button here.
I found a container of old shell and mother of pearl buttons from the 1920s. Some were hand faceted and had interesting dome shapes. I thought it would be nice to reproduce them as gemstones. So, I designed the “Button.”
Cutting this design is simple. It’s basically a round brilliant variation with a very high light return. I prefer it in a larger size (8 mm or greater) and in lightly colored material. It has very nice sparkle and will also deepen light colors quite a bit.
Enjoy cutting your own “Button.”
