Which ring is considered as one ring according to the standards?

The concept of a "ring" in certain contexts often encompasses different types of rings and their significance. In this instance, a wedding ring set is considered as one ring because it typically includes both engagement and wedding bands that are designed to be worn together. This set is often seen as a singular piece of jewelry, symbolizing the unity and commitment of the marriage.

In contrast, a simple band, while it could be interpreted as a single ring, does not include the layered symbolism associated with a wedding ring set. Similarly, a thumb ring and an oversized ring are individual pieces that lack the specific association and meaning that a wedding ring set conveys. The category of a wedding ring set holds additional cultural and emotional weight, reinforcing its distinction as a singular unit according to the standards you are studying.
