| description | The invention relates to a method for producing a gemstone (10), in particular for a timepiece, from a single-crystal mineral body, the gemstone (10) comprising holes (8). The method comprises an ablation step in which the body is subjected to material ablation by scanning at least one face of the body with ultra-short pulsed laser radiation, the duration of which is less than one hundred picoseconds and the beam of which is guided by an at least three-axis precession system, the precession system is configured to at least partially eliminate a conical focus angle of the laser, and the laser ablation step comprises digging a cone (12) at the entrance of the hole (8). The invention also relates to a mineral gemstone of the single crystal type, in particular for a timepiece, said gemstone comprising a face (6) provided with a hole (8) formed in the body of the gemstone (10) and a functional element at the entrance of the hole (10). The functional element has the shape of a cone (12).
