Czochralski Ruby Rough

Also known as "pulling," the Czochralski process is also used to grow single silicon crystals that are cut and used as silicon wafers (which seemed appropriate, given this is meant as a gift to a creator of a programming language). This is a more time-consuming, expensive process than the verneuil (flame fusion) process commonly used to create lab-created gem rough, is of higher quality, and allows for larger finished stones.

 

The gem was cut from red corundum (which is what a ruby is -- any other color of corundum is a sapphire).
