No, they never made it for sale as far as I am aware. Skinnydogdesign out of Long Beach, CA designed the ring, and several versions of it for different shots in the movie. They do custom work and prop work for television and movies.

Look under Filmography for The Sorcerer’s Apprentice and you’ll see some explanation of the ring. They even explain their design process for their work in general on their site.
You might be able to have a ring made like it somewhere (would depend on copyrights of course), but you’ll definitely pay a good price for it. It’s an awesome design though!
