The beads from the 11th and 12th century cemetery at Bratislava´s Devín Castle were analysed with help of the X-ray diffraction analysis with Goebel mirror and Raman spectroscopy. The orange-red and violet beads, sometimes in older literature marked as amethyst beads, were selected for the study. Mineralogical composition of the individual beads was determined according to the macroscopic signs and experimentally obtained data. While violet beads are made from fluorite, the orange-red ones are made from carnelian. The fluorite as well as carnelian beads are imported, since fluorite and carnelian do not occur in Slovakia in sufficient quality. Based on the distribution of deposits with the occurrence of fluorite and fluorite beads it may be expected that the raw material comes from Germany, Austria or Bohemia. As far as carnelian is concerned, because of the missing data about a detailed mineralogical and chemical composition of beads and potential raw materials, it is not possible to determine the provenance of raw materials used for their production.

Presented study focuses on quartz crystal finds in archaeological contexts, from the late prehistory through ancient history to the medieval period. Presence of artefacts made of crystal, as well as pieces of raw semi-precious gemstone variations of quartz on different types of archaeological sites and in features dated to the wide time range are analysed. Main impulse for writing this paper was the discovery of a unique crystal icosahedron in the horseman grave 208/87 at the graveyard from the period of Avar Khaganate in cadaster of municipality Čataj, location Zemanské-Gejzove, district of Senec. This artefact, together with similar finds dated to earlier or later time periods, are viewed in wide chronological and geographical context. The authors search for similarities and differences between them, and try to explain them. Selected finds of quartz crystal and beads made from this material from the territory of Slovakia, dated from the prehistory, but mostly to early historical period and Middle Ages, were analyzed using the Raman spectroscopy method.
