Venetian pair of Murano table lamps, each with three stacked "avventurina" glass balls with black glass rings and base. Rewired for the US. The height of the glass is 19.25 in. Avventurina: Clear glass with 23-karat gold flecks, creating a shimmery, metallic look. The process was aptly named, as it means "adventure" describing the difficulty of working with this process.
