# Jewels 10th Ring

Jewels 10th Ring was a mixed martial arts (MMA) event held by MMA promotion Jewels. The event took place on October 10, 2010 (2010-10-10) at Shin-Kiba 1st Ring in Koto, Tokyo, Japan. It hosted the opening round of the second Rough Stone Grand Prix.

## Background

On August 21, 2010 (2010-08-21), Jewels announced that the event would begin the second Rough Stone Grand Prix.
The first fights were announced on September 10, 2010 (2010-09-10), along with the announcement that Seo Hee Ham's conflicting schedule led Jewels to release her. Ham's replacement was to be determined with the bout between Celine Haga and Saori Ishioka. More fights were announced on September 23, 2010 (2010-09-23).
Sixteen-year-old kickboxer Mizuki Inoue made her mixed martial arts debut on the card as part of the -56 kg bracket of the Rough Stone Grand Prix.
The weigh-ins were held one day prior to the event. It was later announced that Ham would return to Jewels in December to reclaim her place in the Lightweight Queen Tournament semi-final. As a result, the bout between Ishioka and Haga was changed to a regular match.
