The Russian rock crystal used in the bonbonnière is exceptionally fine and clear. Franz Birbaum, Fabergé’s workshop manager commented in his memoirs that the material,
‘demanded of the craftsman a particular skill and its setting was entrusted only to the most experienced Workmaster. It could not tolerate the slightest heat and the settings were never soldered, even with tin’
The gold settings of the bonbonnière are enamelled rich translucent red and mounted with diamonds. The flux for red enamel contains gold and was the most prized and costly of enamel colours used by Fabergé.
A similarly mounted nephrite bonbonnière is in the collection of the Hillwood Estate Museum in Washington.
