Four Patents cover this technology. 
Much like a microchip fabrication process, we start with a lithographic process to etch over 6 billion pixels in a cleanroom. We then grow archival metal into the image and form it as a disc. The disc is optically bonded individually by hand to a watch crystal and then mounted into a pendant made from hand machined 304 stainless steel. The center piece is the Pi symbol made up of millions of diffractive elements to make it glow when a single source light hits it.
