This paper synthesises and analyses archaeological data on the Nitrianska Blatnica II hoard of metal artefacts (Ha C1a; 800–725 BC) from the hilltop settlement of Marhát. Currently, this is the largest metal deposit from the Final Bronze Age in Slovakia, providing a fundamental chronological synchronization of the Ha C1a sub-phase with Northern Italy and Central and Southeastern Europe. A spectral analysis of the serial circular jewellery shows a uniform origin from a unique metallurgical workshop and contributes to the scientific discussion with important data on economic operations in the Carpathian Basin. The closest analogies to the bronze vessels and gold cylindrical earrings come from the most important contemporary sites of the Hallstatt and Mezöcsát cultures and stimulate the notion of a large intercultural trade in prestigious goods and the practices of the aristocratic population of the Final Bronze Age in Central Europe.
