Enamel is a wonderful material for jewellery and precious objects, although time and use can bring damage. The art of enamel restoration focuses on not only regaining a fine appearance but matching the original craftmanship.
The Tiffany watch shown is a good example of their craftsman's art. Lustrous enamel and diamonds, on an 18ct gold base, with a few signs of wear from a century of use.
A patch of white and the gold underlay can be seen in the lower left area of the ribbon, then a much smaller white spot, high up on the left. Although not so evident, the enamel there has a wider bruise, the sheen has gone.
On the watch case itself, there is a tiny diamond missing from the centre and the enamel this sat in is fritted around the edges. Minor damage in a sense but detracting from the beauty of a finely made piece.
