Polished Gems

Our rough is personally sourced worldwide then brought to skilled cutters in based in Antananarivo Madagascar where we work with a young cutter developing his business, to the gem district of Silom in Bangkok where master cutters create there masterpiece stones or to local cutters based in Australia keeping the mine to market chain as close to home as possible. From decadent pieces of stunning aquamarine delved from deepest Mozambique to locally mined Australian Sapphire in its true unheated deep blues we strive to bring stones to meet all needs.
