This item is crafted with Blacksmithing (415); taught by trainers.
Note that it can be added to a belt that already has one or two sockets.
Only one belt buckle can be added per belt.
Gems added to the socket will not help you achieve the color match bonus of the item, however they do contribute towards activation of a Meta gem.
The Eternal Belt Buckle will not work on items of iLevel 300 or higher, ruling it out for use with Cataclysm armour. The is used instead.
