Description

Fiorite is the name given to a type of opal, or more precisely, a
fine-grained, often pearlescent silica sinter formed by deposits of hot spring water (geyserite), first described from the region around Fiora in Italy (hence the name). Here we have a specimen that is abundantly covered with cream-colored, spherical fiorite crusts and comes from this locality of first desciption.

Comes with an old label of the italian enterpriser and collector Guiseppe Garbari. He was born in Trento, Italy, on June 27, 1863 and died in Florence on June 6, 1937. Garbari had contacts with many prominent mineral collectors and dealers around the world. His mineral collection was especially rich in specimens from Italian localities, and from localities in Slovakia, particularly Banská Štiavnica and Kremnica. Garbari's mineral collection was ultimately sold to the firm of Friedrich Krantz in Bonn, Germany, and was dispersed to many private and institutional collections. A number of Garbari specimens are preserved today in the Freiberg Mining Academy's Mineralogical Museum.
