A pair like this does not need much around it. The mix of rounded form, soft amber tone, and fine linear pattern gives a shelf, table, or console an easy focal point, whether you add a few stems or leave the glass to speak for itself.

Mario Colelli was a Murano-associated glassmaker known for technically demanding filigrana / filigree work, in which fine colored canes are embedded into clear glass to create linear optical patterns. In Rosenthal Glasstudio pieces attributed to him, that Venetian craft vocabulary is paired with a more reduced Northern European design language.

Hertha Bengtson (1917–1993) was a Swedish ceramic and glass designer and one of the key figures of 20th-century Scandinavian design. She began at Rörstrand in 1941, became especially known for combining beauty with function, and later worked as a freelance designer for Rosenthal from 1969 to 1981, where she developed several porcelain services and design objects with her characteristic clarity of form.

Rosenthal, founded in 1879 in Selb, Bavaria, is one of Germany’s most important porcelain manufacturers, recognised for combining industrial production with high design standards. With its Studio-Linie programme from the 1960s onwards, Rosenthal invited international artists and designers to create avant-garde forms and décors, making pieces like this set both functional objects and design collectibles.
