Fish-Form Bottle Opener with Mother-of-Pearl Inlay

A bottle opener cast as a fish and inlaid with mother of pearl is a small object; the ambition behind it is not. Fish motifs run throughout the Los Castillo documented output — Morrill (1996) records fish-form jewelry from the 1940s onward, including a fish tail necklace and cuff dated to 1940–45 — and this functional piece extends that same vocabulary into table silver, carrying a signature workshop motif out of the jewelry cabinet and into the domestic register.

The mother-of-pearl inlay across the fish's body places the piece within the workshop's established practice of working non-silver materials into sterling settings. Los Castillo's inlay vocabulary encompassed tortoise shell, onyx, and crushed stone alongside silver (Morrill, 1996), and nacre — lustrous and tonally crisp against polished metal — belongs to the same sensibility. The effect rewards close looking: the iridescent surface animates a form that, as a tool, depends entirely on its silhouette.

The fish bottle opener stands as a quiet measure of the range Los Castillo sustained across the medium.
