Description

A single greenish topas crystal, likely from Sherlova Gora, Nerchinsk, Transbaikalia, Eastern-Siberian Region, Russia. From the collection of A. A. Damour (1808-1902), a well-known french mineralogist. His personal mineral collection was sold to F. Krantz (who was in charge of the Krantz mineral dealership between 1891 and 1926),
probably shortly after his death. Damour was sufficiently famous that Krantz had special labels printed identifying the specimens from the
Damour collection (but this caused a lot of the original hand-written labels to vanish).
Weight: 43 grams
