These are two 1970s Mid-Century Modern wall sconces crafted by Mazzega, a renowned Italian glassmaker known for its Murano glass designs. Each sconce features a rounded, slightly irregularly shaped shade made of opalescent Murano glass, with a textured surface that gives it a shimmering, organic quality. The glass exhibits a beautiful play of light, with subtle opacity and translucency that enhances the fixture’s glow when illuminated. The design reflects the period's fondness for artisan glasswork and organic forms, making these sconces iconic pieces for Mid-Century Modern decor. They are likely mounted with simple metal fixtures, allowing the glass to be the focal point. They are in working order, glasses are in perfect condition.
