Abstract: An adjustable fit ring includes a main ring and a plurality of adjusters. The main ring has a ring inner peripheral surface, a ring outer peripheral surface, a front surface, a rear surface, a through cavity formed as a space surrounded by the ring inner peripheral surface, and a slot formed on the ring inner peripheral surface. The plurality of adjusters are received in the slot of the ring inner peripheral surface. The adjuster has an adjuster inner peripheral surface, an adjuster outer peripheral surface, and a resilient element installed on the adjuster outer peripheral surface to push against an inner wall of the ring outer peripheral surface, the adjuster being connected to the main ring to move between a resting position and a pressed-in position.

Abstract: An interchangeable ring having a main ring which has a ring loop. The ring loop has an inner surface portion, an outer surface portion, and a through cavity formed as a space surrounded by the inner surface portion. The interchangeable ring also has an interchangeable stone setter having a spring loader operatively engaged with the main ring, a connector, and an engaging stone setter which is selectively configured between an unengaged position which the engaging stone setter detaches from the connector through the spring loader, and a locking position which the connector engages with the engaging stone setter through the spring loader.

Abstract: A foldable ring includes a main ring and a flipper. The main ring has a first inner peripheral surface, a first outer peripheral surface, a first front surface, a first rear surface, and a first through cavity formed as a space surrounded by the first inner peripheral surface. The flipper has a second inner peripheral surface, a second outer peripheral surface, a second front surface, a second rear surface, and a second through cavity formed as a space surrounded by the second inner peripheral surface. The flipper is pivotally attached on the first front surface to move between a first and second position. In either the first or second position, the flipper is arranged to overlap on the first front surface and that the first through cavity is arranged to align with the second through cavity to allow a user's finger to pass through both main ring and flipper.

Abstract: A halo effect ring has an inner halo fixedly connected to an inner ring, and an outer halo fixedly connected to an outer ring. Both rings can have gems in settings and other ornamentation, and when combined, the halos are in concentric circles, when viewed from above, with at least part of the inner ring or it's setting or other attached parts rising through the outer halo. Another outer ring is hingedly connected to the first outer ring, and removably connected to the outer halo such that the halo can sit flush with a top side of the outer rings.
