In 2001, an article appeared featuring a 14.02ct stone as the first and only gem quality Jodachidolite. The suspected origin of this stone was Mogok, Burma. With the constant study of this historic gemstone deposit, it was later confirmed that Mogok was indeed the source of this new gemstone material. More specifically, Jodachidolite is found in the Pain Pyit mining area a few miles northeast of Mogok. Along with rubies, sapphires, scapolites, and spinels, this area is also known for the occurrence of other borate minerals including danburite and poudretteite.

The exact deposit of the Jodachidolite is known as Pyant Gyi. This locality was mined extensively in 2005 after the discovery of Hackmenite. Since most of the rocks were hammered to retrieve the hackmanite, little attention was paid to the small associated orange Jodachidolite crystals, and most of them were was lost or destroyed.
