As is the case for many superb inventions, Aventurine glass was created by accident. In the 19^th century, a glass-blower in the Italian city of Murano happened to spill some copper shavings into molten glass. This gave rise to Aventurine glass, now a much sought-after material, scattered with metal inclusions and named after the Italian expression "a l’avventura", literally "by chance" – a tribute to this lucky twist of fate. 

Parmigiani Fleurier is a pioneer in the use of Aventurine in watchmaking and has numerous special editions that showcase the material on their dials. These pieces are called "Galaxy" as a reminder of the sparkling constellations evoked by the material. Likewise, the Kalparisma Nova Galaxy represents a star-scattered sky that tells the story of the passage of time. The delta-shaped hands are skeletonised to better reveal the celestial display and to enhance the watch's delicate femininity.

One of the principal high points of the Kalparisma collection is its small seconds at 6 o'clock, which takes the form of a star performing one revolution per minute. Halfway between a watch function and a marvellous decoration, the "Nova" is inspired by a piece from the Maurice-Yves Sandoz collection that was restored at the Parmigiani Fleurier workshops. On the reverse of this pocket watch, a number of stars began to turn whenever the minute repeater was activated. Michel Parmigiani was captivated by this animation and knew that he would one day transcribe it into a women's watch, many years before he began to design the Kalparisma. Restoration has always been the soul of Parmigiani Fleurier, inspiring its present-day creations. This little star has found its ultimate place at the heart of a dial designed to represent the galaxy. In astronomy, "Nova" refers to a star that suddenly becomes very bright. This burst of light aptly describes the Kalparisma Nova Galaxy.
