Timepiece part, and method for producing such a timepiece part

A timepiece part comprising:

• at least one colored transparent stone wherein said colored transparent stone comprises a crown portion and a pavilion portion which has an end extremity;
• and
• a mount comprising at least one aperture for receiving said colored transparent stone;
• wherein
• the ratio between the height and width of said colored transparent stone is lower than 50%;
• said mount is made of anodized titanium or anodized aluminum;
• the at least one aperture has lateral surfaces;
• said lateral surfaces comprise:
• first lateral surfaces arranged for receiving the crown portion of the colored transparent stone;
• second lateral surfaces arranged for receiving the pavilion portion of the colored transparent stone;
• third lateral surfaces arranged for receiving the end extremity of the colored transparent stone;
• the at least one aperture is a through aperture, and comprises a first end at said crown portion of the colored transparent stone, and a second end at the end extremity of the colored transparent stone;
• first, second and third lateral surfaces are anodized, the anodization process being performed after the setting of the colored transparent stone, by exploiting the second end of the through aperture, so that the anodization process reaches first, second and third lateral surfaces.
