Abstract: Rings having variable sized annular openings and methods for making and using such rings are disclosed. A ring is disclosed that includes a ring shank having inner and outer circumferential surfaces, where the inner circumferential surface defines a maximum circumference of an annular opening of the ring shank, and a clasp that includes a first end portion hingedly connected to the ring shank and a second end portion. The clasp is rotatable between a secured position in which the second end portion is securably engaged with the ring shank and a plurality of unsecured positions. The clasp may include an arcuate portion and at least one protrusion that narrows a cross-sectional area of the annular opening when the second end portion is securably engaged to the ring shank.
