Production perspectives of a high-status polychrome jewellery set from the Hunnic period (mid-5th century AD) Carpathian Basin

Fifty years after the discovery of the Regöly grave, the emblematic Hunnic period archaeological assemblage from Hungary, an extensive scientific investigation was performed on the polychrome dress accessories of the high-status woman, often referred to as the “Princess of Regöly”, buried there. The multi-instrumental analyses aimed to characterise material and technological aspects of the gemstone-inlaid artefacts (a set of a pair of bow-brooches and a belt buckle), i.e., the manufacturing and decorative techniques as well as the chemical and mineralogical compositions. The non-destructive and non-invasive gemmological and geochemical analyses applied optical microscopes, handheld XRF, SEM-EDX and Raman microspectrometer. This study provides the first comprehensive examination of the Hunnic period polychrome jewellery, and highlights the potential of combining surface and subsurface analyses to specify garnet provenances. It presents the first evidence of use of antique and early medieval garnet sources during the early Migration period. The findings enhance understanding of the garnet supply chain and trade network, the production organisation and potential workshop connections. Significant differences of the brooches and the buckle reveal varying levels of luxury among the elite, providing insight into the social context of the polychrome jewellery associated with the “Princess of Regöly”.
