This Art Nouveau Brooch had extensive
damage to the green enamel. We restored the translucent green enamel
taking care not to make it too dark otherwise it would not keep its
translucency and the overall effect would be lost. Greater temperatures
can be used when dealing with diamond set pieces as they are originally
formed under great temperature and pressure, other stones however
like agate must be treated with care so as they do not discolour.
