Sterling silver ring forging workshops in downtown San Diego bring participants to METHRA's bench studio at 710 13th Street, where each guest hammers a 925-grade band from raw bar stock to wearable ring in a single session. The tanzo forging method — shaping heated metal on a steel mandrel with a wooden mallet — yields structurally denser bands than lost-wax casting, a metallurgical distinction that separates the process from the welded permanent-jewelry format at BIJUT Collection Permanent Jewelry. Each workshop covers shaping, soldering, filing, sanding, and optional hand-stamped letter engraving with metal dies before a final polish. Private bookings accommodate corporate team-building groups, bachelorette parties, and couples alongside the standard workshop format. That group-event capacity positions the studio as a pre-ceremony activity for wedding parties coordinating receptions at nearby venues like Wedgewood Weddings at The Headquarters. Advanced-course enrollees access the full studio bench for up to twelve hours across multiple sessions to master textured hammered-band fabrication and precision hand-engraving techniques in 925 sterling silver.
