The refined goldsmith production by Roberto Costa and Sandra Arca builds on the high-quality traditional crafting of filigree and coral with virtuous style and fine technical interpretations, original and rich in decorative and sculptural details. Born in Alghero, a small town set on the renowned coral coast in the north-west of Sardinia, where they also grew up, they both undertook educational and professional paths in the domain of the creative goldsmith craft. Roberto was positively affected by the artisanal atmosphere in the workshop of his father Antonio, a goldsmith of the momentous generation that in the 1950s was part of the relaunching of the local goldsmith’s art in Alghero. Roberto then specialised in jewellery at the School of Art, where he improved the technical skills learned in the family workshop, thus acquiring know how in the design of jewels, thanks to which he created his own distinctive experimental style. Sandra also attended the School of Art specialising in the crafting of coral, she then continued her studies and graduated in History of Art. In 2002, when Roberto and Sandra set up their own workshop in the evocative historic centre of Alghero, they combined their skills in a successful business that strengthens their inspirations, as revealed by their refined original production of unique jewels of great scenic impact.
