3 Perfect Gems (of any type) + 1 Magic Item question

This recipe doesn’t work in NON LOD? I tried and it won’t transmute. I can’t remember if it has to be of a certain level magic item or not thou. I can’t find classic recipes online anywhere, I’ve looked so many websites.

There is only a handful of recipes for calssic. The cube back then was mostly used to combine gems and pots into better ones.

yah I knew it was limited but I didn’t realize it was as limited as is.
