It's not uncommon at all to find bezel settings that were handmade/hand-jigged with gold , esp with cameos , Roderick .
Often , rather fragile cameos would get cracked or chipped when inserting/installing them into cast-metal bezels , as the cast type are pretty much thicker-walled & take much more force to 'bend' around a setting .
The cost of buying manufactured 'findings' (metal items for mounting stones & etc.) led many cameo producers to just make their own , including cast-metal ones (usually from lost-wax method) .
The reverse is true today , in general , with manufactured findings .
