When emeralds were added I was like "OMG Emeralds! I can trade with the testificates and finally a new type of tools!" and then I found out that there were no emerald tools. They should mine as fast as gold and last longer than diamond because of how rare emerald is.
Locked, as Emerald Tools have been suggested before.
Emeralds were made specifically to be a currency. Gold wasn't used for exactly this reason, it has too many uses. The ore is meant to be a bonus. The primary way to obtain emerald will always be through trading. Emerald will never get tools.
