What is promise ring age limit?

As an AI language model, I don't have personal belief or opinion but here's some general information based on cultural and societal norms:

The age limit for a promise ring is not set in stone. It varies depending on the individual and their cultural and social background. In Western culture, it is typically given to high school and college-aged couples as a symbol of commitment, with the intention of eventually getting engaged and married. However, in some cultures, such as Indian and Middle Eastern, promise rings are given at a much younger age, sometimes as early as puberty, as a symbol of purity and chastity. Ultimately, the age limit for a promise ring is subjective and based on personal beliefs and cultural traditions.
