This composite mark consists of a silver purity stamp ("925"), a designer maker's mark ("RLM"), and a country of origin stamp ("THAILAND"). The letters "RLM" represent the prominent American jewelry designer Robert Lee Morris, specifically identifying pieces produced under his commercial diffuse lines, such as RLM Studio. The "925" confirms that the item is composed of sterling silver (92.5% pure silver alloyed with 7.5% copper or other metals).

Jewelry bearing this mark typically features Morris's characteristic sculptural, organic, and modernist design vocabulary—including fluid crosses, bold cuffs, and smooth, contoured pendants. These pieces were cast and finished in Thailand for broad commercial retail and television distribution (such as QVC), making his high-fashion design aesthetic accessible in sterling silver. Companion pieces frequently bear a matching hang tag stamped "RLM Studio 925 THAILAND".

This mark is easily distinguished from Robert Lee Morris's earlier or couture gallery pieces, which are typically stamped with his full name ("Robert Lee Morris"), often made in New York, and lack foreign country of origin stamps like "THAILAND".

As struck on the pieces recorded here, the full run of stamps reads “925 RLM THAILAND”.
