Diamant Auctions

Subarna, a Barcelona auction house, runs both in-person and online sales, with its catalogues spanning silver, jewellery, Oriental art, design, decorative arts and painting, according to past sale titles on its site. The house also holds periodic "déballage" sales, a charity sale called "FAMOSA," and a Christmas direct sale, and its archive reaches back to 2017. The site itself is largely a running list of sale headings and catalogue links, with its next sale listed as "próximamente" (coming soon).
