How do you give a dull finish to gold jewelry?
At home this can be achieved with a piece of abrasive material, a bit like a pan scrubber! In the workshop we use a "scratch brush". In much the same way as a highly polished piece look dull after the scratches of day-to-day wear and tear, then a dull finish will eventually wear shiny. The dull finish, just like the highly polished finish, can easily be restored by your jewellery workshop.
