Pendant 3D model for a cabochon. The bail and the charm are in separate files.
Pendant size without bail and the charm - 52 mm
Stone size - oval 20x15x5 mm
Weight in sterling silver with stones - 15.3 gram
The front and back parts are printed separately and cast in silver. The cabochon is adjusted between the parts, which are then welded with laser welding (it is not that hot as regular welding, so the stone is completely safe). Laser is available in most jewelry workshops now.
