There are only two possible uses for Millerite: you can sell it for a nice 1,000 gil, or you can upgrade a mastered Iron Bangle (starting when you find the Omni-kit in Chapter 4). Since a Silver Bangle costs only 800 gil, it may not seem worth the upgrade, but you will save some money upgrading the Iron Bangle since it is of lower rank. Regardless, you certainly won't want to buy Millerite when it becomes available for sale later in the game, as its 3,000 gil retail price is impossible to justify.
