Creating mythics

Hi guys, just a dumb question here.

If I want to get a Mythic amulet do I have to socket an amulet or can I socket any item and the right combination will give me that mythic ?

I’m asking because I only found head and wand with “mythic” on it in the codex and I own both.

all mythic items have a recipe that requires specific mythstones and specific item types. There should be a few lists on the forum floating around that show the recipe, requirements, and resulting item.
