Where do I find the Transmute receipes?

Cassandra always has great questions:

Ahhh, my generous friend plz help me!
I'm trying to be a master artisan(I'm already one and WitchWarrior101 XD) and I'm having trouble with diamonds.
Evil Theurgist used a diamond transmute recipe, and idk where to buy it.
Do you know where the transmute diamond recipe is, if you DO KNOW where it is?
Thanks a bunch, it means a lot!
