System for sizing and re-sizing articles of jewelry

Abstract

A system for sizing and re-sizing an article of jewelry includes a partially circumferential band typically of a precious metal, and at least a first polar segment both having a like inner radius to that of the article, in which the band and polar segment exhibit opposing complemental radial end surfaces at their polar interfaces. The system also includes elements for selectably axially and pivotally securing the band and segment along linear axes passing through the complemental radial surfaces and polar interfaces. The system further includes at least a second polar segment having a polar parameter slightly more or less than that of the first segment, the band and second segment having opposing complemental radial surfaces at their polar interfaces. An article of jewelry may be readily sized or re-sized by either replacement of the first polar segment by the second polar segment or through a mechanical increase or reduction in polar dimension of the first segment to create a second and re-sized segment.
