Mammalampa The Duchess Marble & Swarovski Pendant, Large 23.6 in

The grand Duchess: a 23.6-inch dome of marble chips and Swarovski crystals, a dramatic, sparkling statement.

The large Duchess is 23.6" across and 11.4" high, and its larger surface lets the marble texture and crystal reflections show at their most dramatic. Swarovski crystals are hand-set among the rough marble chips; one E26 LED bulb up to 50W lights the dome, which hangs on a steel suspension with a textile-lined cord up to 80". White pairs white marble with a white canopy and cord; Gray pairs gray marble with a black canopy and cord. It weighs about 40 lb and ships by truck freight.

About the designer

Ieva Kalēja is Mammalampa’s founder and designer. She starts from the material rather than a preconceived object and describes her approach as intuitive and feminine, sensitive to texture, atmosphere and emotion. Latvian design magazine FOLD reports that Elle Decor named her one of the world’s ten most talented women designers in 2020, and that she chairs the product-design jury of the National Design Award of Latvia in 2026. In 2024 she curated the “Summer” exhibition of design processes at Riga’s Museum of Decorative Arts and Design.

Why we carry it

We have been curating design-led lighting since 2009, and the large Duchess is the most dramatic piece in the collection: stone, crystal and light at architectural scale. Mammalampa is a family company in Riga, Latvia. Designer Ieva Kalēja started it with her sister after returning from her studies in Milan, and their father became the studio’s technical expert. The name joins “mamma” (origin, care, the human touch) and “lampa” (light), and every lamp is made by hand in Latvia from natural materials such as paper, stone, steel, canvas and crystal, with as little machine work as possible. According to Mammalampa, its lamps have been installed in projects such as Tom Aikens’s Tom’s Kitchen restaurants in London, Marie Burgos Design interiors in Manhattan, the Story27 offices in Los Angeles and the Dome Hotel in Riga.

Buy once: durability and care

Mammalampa’s care advice: clean gently with a soft, dry cloth, avoid abrasive materials, and always switch off the power before cleaning. A soft brush lifts dust from between the marble chips (our advice). Have a licensed electrician install it. Mammalampa lamps carry a 3-year warranty.
