Murano handblown vases of opaline glass made by prestigious Italian glassblower, Sergio Costantini. Clear glass with polvere d’oro (23-karat gold leaf flecks) is layered over white opaline glass, creating beautiful “incamiciato” glass. Extraordinary luminescence and scale, with slight iridescent quality. Ribbed on three sides. From 1980, signed Costantini at base.
