Rings are the most common kind of jewelry. There are varieties of rings: child’s, ladies’, men’s, unisex. Some of them have symbolic meaning, for example engagement rings or wedding rings. There is a ring for every finger.
Rings, like all products, can be simple and complex. To simple rings jewelers include rings that are relatively simple to make. They are oval-shaped rings (having a segment in cross section), flat-shaped rings (having a rectangular cross-section in cross section) and rings with a stone (consisting of a simple caste and a shinka). A caste is a rim of stone, a shinka is a rim, wrapped around a finger.
Complex rings are considered to be complex in construction, and therefore in manufacturing. Complex rings can be time-consuming and laborious in assembly and processing. These are rings with openwork castes, multi-stone rings, rings with repeated patterns, filigree, engraved, etc.
Dimensions of the rings are determined by their internal diameter: from 15.5 to 24.0 mm. If, for example, the inner diameter of the ring is 18 mm, the ring size will be 18. The subsequent size of each ring differs from the previous one by 0.5 mm. The size of the ring can be determined with ring-collar (collar).
