Infinite Sphere - does it exist?

I’ve selected some customisation option on Best in Bags and requested 75 NR for Anub. It has asked me to find a +5 resist gem called Infinite Sphere.

Does this actually exist in game? Wowhead suggests it doesn’t (at least the comments from 2009 say that).

I can remove that item, yeah looks like perhaps it was only in a beta at some point (annoying that Blizzard just leaves junk items hanging around in their data, but so it is).

For now you can exclude that gem from optimizations until I update the site (to do that first click on a gem socket in the optimized solution, then search for the gem in the list, then click the exclude icon to the right of it, which will turn red when it is excluded – picture below):
