Etui van goud, versierd met honderd verschillende stenen, een staalkaart van Saksische gesteenten c. 1770

"Etui van goud, versierd met honderd verschillende stenen, een staalkaart van Saksische gesteenten" (Case of gold, decorated with one hundred different stones, a sample card of Saxon stones) is a small, intricate box created by Johann Christian Neuber circa 1770. The gold box, measuring 9.0 cm in height, 5.9 cm in width, and 1.1 cm in depth, is adorned with a mosaic of one hundred carefully selected, oval-shaped gemstones, representing a diverse array of Saxon stones. The box serves as both a decorative object and a showcase of the rich geological diversity of Saxony. This piece demonstrates Neuber’s mastery of goldsmithing and his keen eye for detail, as well as his interest in the natural world.
