925 sterling silver mother of pearl pendant Pin Or Necklace Native 6.9 Gr BROCHE

Entirely .925 solid sterling silver and inlay mother of pearl. Both a pendant (large bail on top for a chain) and a fully working pin. Stamped "925 Sterling BROCHE ALPACA" I picked this up when I lived in San Diego. The inlay design I believe is depicting a firebird (Mexican?) Please see all pics for details, weight and size. ds rb4
