Hi Lesley, My sandblaster would not achieve such course texture, the machine that Peter has would be a better option. I would say that the jewellery would need scratch brush polishing after such blasting as sand blasting leaves a dull matte finish. If you had patience you could achieve a similar effect by texturing with a hammerhead attachment in a flexshaft drill. I use my hammerhead when texturing carved animals and such like. The same effect can be achieved with chasing tool punches and a hammer. I also use my scratch brush, a rotating brass bristle brush, when creating a fine matte finish like the background to this crest.
