If you need a little box to hide a precious piece of jewelry, you pretty much can’t beat this. (Though it was originally used for snuff.)
Above is one of the gemstone snuffboxes created by the German goldsmith Johann Christian Neuber (1736-1808), working in Dresden, the cosmopolitan capital of Saxony. Nearly 30 of these boxes, generally no larger than the palm of a hand, dominate “Gold, Jasper and Carnelian: Johann Christian Neuber at the Saxon Court,” on view at the Frick Collection.
