An extraordinary and highly collectible mid-century modern mushroom table lamp produced by the prestigious aureliano toso furnace in murano, italy, during the late 1970s. This specific piece represents a luxury custom-grade variant of the classic mushroom lamp, boasting premium materials and official documentation that secure its authenticity. a masterpiece of materials and luxury details the amethyst gems: unlike standard production models, this lamp features 3 massive, hand-shaped murano glass inserts in a rare amethyst purple hue. Bound in polished brass claws, they act as safeguards for the glass shade while creating a magnificent color contrast. hand-blown glass: the generous mushroom shade (40 cm diameter) and the elegant central stem are crafted from pristine hand-blown incamiciato satin murano glass. Weighing a substantial 4.4 kg, the density of the glass ensures a perfectly uniform, soft, and glare-free ambient glow. organic silhouette: the intentional slight organic tilting of the stem and the asymmetric arrangement of the three arms are absolute proof of its 100% handcrafted nature. It is a sculptural light born exactly this way in the furnace. advanced 1970s technology original relco milano dimmer: the lamp is equipped with its ultra-rare original 1970s relco milano floor dimmer in a matching bronze-gold finish.
