is a third-generation Viennese jewelry dealer, collector and designer. Her grandmother, Lola Demner, founded the eponymous family business DEMNER in a tiny yet elegant shop in Vienna, having arrived in Austria from Poland in 1947 with next to nothing. Natascha’s father, Henry Demner, brought the business to the United States in the 1980’s, opening a boutique on Manhattan’s Upper East Side. The family’s gallery DEMNER specialized in eclectic vintage and 20th-century jewels and remained a prominent Madison Avenue feature for more than 20 years.

Today, while staying faithful to her family’s history, Natascha continues to generate a dynamic future for the collection. In addition to her original designs — streamlined, modern 18K gold jewels— she converts classic pieces into daring new objects. While retaining the pieces’ original character, she refreshes them with her impeccable taste and expertise. The result is a jewelry collection that weaves together elements from different periods, distinctively unique and always wearable; pieces that match the lifestyle of the eclectic group of collectors that are her clients.



is an Italian jewelry designer who has enjoyed an extraordinary 30 years career spent between the very best of two worlds: New York City and Venice, Italy.

Forever in search of exciting new materials that inspire her imagination, she creates pieces incorporating unusual gemstones, exotic woods, resin, and other unexpected and rare materials.

This tireless quest for the exceptional has yielded gorgeous and complex one-of-a-kind jewels that gracefully marry the precious
with the non-precious. Her creations are set in 18K gold or sterling silver, and all wood and resin components are hand carved and carefully finished in small ateliers around Italy.

Ever since becoming a designer, Antonia has insisted on remaining closely engaged with her collaborators, establishing loyalty,
trust, respect, and passion as the foundations of her business. She is enthusiastically committed to supporting the glorious but
endangered world of Italian craftsmanship and personally supervises the creation of every piece.

In 2007 Antonia opened her orange jewel box store on Calle delle Botteghe 3127, Venice, Italy, a boutique that serves a
clientele as international and stylish as she.





In 2015 these two extraordinary women joined forces and opened DemnerMiletto in the heart of New York City.

Their appreciation for high-quality materials, exceptional craftsmanship and personalization is reflected in the design of the salon. The space features dramatic high-ceilings, a custom porcelain light installation and walls of pale, calm gray that provide their international clientele with a refuge from the busy streets below and a truly discreet and unique experience.  

 Alongside their jewelry collections Natascha and Antonia curate and present one-of-a-kind objets d’art and the work of notable independent European designers.

DemnerMiletto offers several custom services including reimagining family heirlooms and bespoke designs. Both certified gemologists, Natascha and Antonia also specialize in stones sourcing and enjoy working hand in hand with their clients to create custom-made pieces, specialized gifts for young collectors, unique engagement rings, and one-of-a-kind cuff links.
