The Simon Gauntlet is currently worn and used by the Simon Famiglia's tenth generation Boss, Enma Kozato. When activated, the Earth Simon Ring transforms into a pair of gauntlets reaching up towards the forearms, surrounded by rings of text. When used in battle, the gauntlets create spheres of dense gravity around opponents; this was first demonstrated by Enma against the Vongola Guardians during the Inheritance Ceremony. The Vongola Guardians were smashed into walls by the intense gravitational field. The gauntlets are not limited in their form of gravity manipulation, as Tsuna was simply smashed where he stood as well as against the wall behind him.
After the Simon Rings were upgraded by the Vongola Sin, the Simon Gauntlet, when used, have notably changed in appearance; on one side of Enma's arm, the gauntlet went further up his arm, extending to his shoulders while forming a wing-like armor on his shoulder. On the other side it changed to have the Simon Famiglia emblem on the center of the back hand. The gauntlet's abilties of gravitatial manipulation also increase even further then before, shown during Enma's temporary fight with Tsuna. Also, similar to the X-Gloves that are possessed by Tsuna, the gauntlet can release Flames for propulsion and levitation.
