The possibility of performing non-destructive analyses $in situ$ has made XRF spectrometry a successful technique for Cultural Heritage materials. This paper discusses the $in situ$ investigation of the fragments of a processional cross by Nicola da Guardiagrele (1385-1462), one of the most important Italian goldsmiths of the $15^{th}$ Century. The composition of all materials as well as the thickness of gildings and enamels were determined by combining conventional XRF and micro-XRF methods. Particular surface effects due to the gilding and enamelling techniques were also observed.
