Abstract: A method for producing a partly transparent body with a color gradient, include: providing a transparent first casing having a first joint surface on a protrusion and including an encased object; providing a second casing which is not completely transparent and which has a second joint surface in a recess. The shape of the protrusion and the shape of the recess correspond to each other; and combining the first casing and the second casing by inserting the protrusion into the recess and melting the first joint surface of the first casing with the second joint surface of the second casing. A pressure force and a temperature are applied to the first joint surface and the second joint surface such that the first joint surface of the first casing transitions into the second joint surface of the second casing in a visually seamless manner, followed by a removal of material.
