History After the women’s MMA promotion Smackgirl faced severe financial difficulties caused by unexpected departures from major sponsors and television network deals, an executive from the Japanese event production company Archery Inc., Yuichi Ozono, formed the company Marverous Japan, who acquired the assets and rights formerly belonging to Smackgirl parent company Kilgore. Since the reputation of Smackgirl was tarnished by all the problems it faced, it was decided to start anew.

On June 9, 2012, it was announced that Jewels has formed a strategic partnership with American promotion Invicta Fighting Championships to cross-promote the world's top female fighters on their respective fight cards in the United States and Japan.

On , Jewels announced that it would cease operations as an independent company, with Yuichi Ozono, then head of Jewels, stepping down and Shigeru Saeki from Deep, formerly supervisor, taking the full direction. This move transferred fighters and the promotion’s image to the new Deep Jewels brand, which would be managed by Deep.
