Abstract
A method for fabricating a timepiece component partly formed of aventurine, including providing at least one piece of aventurine formed of a mass of coloured glass containing copper crystals scattered throughout the mass; grinding at least one piece of aventurine to obtain a granular powder; depositing at least part of the granular powder on a surface of a support intended to receive a decorative coating; then introducing the support with the granular powder deposited on the surface into a furnace and melting this granular powder so as to obtain, after removing the assembly thus obtained from the furnace and allowing the assembly to cool, an enamel layer made of aventurine which covers the support surface. The timepiece component is, for example, a dial, a moon phase disc or a bezel.
