is a pms 14k stamped on ring old and worth anything?

A ring stamped with "PMS 14K" typically indicates that it is made of 14-karat gold, and the "PMS" may refer to the manufacturer or designer. The age and value of the ring depend on factors such as its design, condition, and market demand. To determine its worth, consider getting it appraised by a professional jeweler. Vintage or antique pieces can sometimes hold significant value, especially if they have historical or aesthetic appeal.
