World's longest printed digits of Pi.  And Smallest.

Amaze and impress your friends with the only pendant in the world that contains 7 millions digits of Pi.  Actually it's 7,150,000 digits of Pi.  View with a microscope or use the QR code viewer app to see the etched digits.

4 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.  You would be the talk of the party.

We only made a limited quantity for this Christmas season.  Get it while it lasts.
