What does a silver ring with 925 and a circle with DL inside?

A silver ring marked with "925" indicates that it is made of sterling silver, which contains 92.5% pure silver and 7.5% other metals, usually copper. The circle with "DL" inside likely represents the manufacturer's or designer's logo or initials. This marking can help identify the brand or artisan who created the piece. Together, these markings suggest the ring is both a quality silver item and has a specific designer association.
