It appears the OP has found the answer to their query, but for anyone else who may have this issue...
Players do not craft relics directly. Rather, there are recipes to craft items. You barter those items for Sealed Relics at a Guild Master. Then, you take the Sealed Relic to a Relic Master to deconstruct and are able to equip the Relic onto an LI.
Now, some of the Sealed Relics are tradeable, and some are bind on acquire. The tradeable Relics are either the Bridle Relics, or each crafting Vocation has a unique stat.
Cook - Morale; Scholar - Power; Metalsmith - Might; Weaponsmith - Vitality; Woodworker - Agility; Jeweller - Will; Tailor - Fate
The bind on acquire Relics are able to be found in any guild, so anyone can acquire them and them being tradeable isn't necessary.
