The eye of the lapidary

This is definitely the activity of the lapidary that requires the most comprehensive knowledge of gems.

The challenge of cutting is to produce the finest cut stones in terms of brightness, intensity and colour while maintaining the maximum weight after cutting. The interpretation of the uncut stone is therefore a key stage.

Working on center stones

This involves bringing out the brilliance of the stone by shaping, cutting and/or polishing. Lapidaries can give it a new shape, alter the size or modify the faceting. They pay special attention to the quality of polishing, which has a direct impact on the beauty of the stone. They strive to retain the maximum weight.
