The Slovenian stamp for the year 2005 in the Minerals series is indeed Zoisite.
Here are the details about the stamp:
- Mineral: Zoisite
- Issue Date: March 18, 2005
- Significance: The stamp was issued to commemorate the 200th anniversary of the mineral’s naming.
- Named After: Baron Sigmund (Žiga) Zois (1747–1819), a Slovenian scientist, mineralogist, and patron of the arts and sciences during the Enlightenment. He was given the first specimens of the mineral found in Carinthia (modern-day Austria/Slovenia) and provided them to mineralogists who officially described it in 1805.
- Depiction: The stamp features a specimen of Zoisite from Zois’s original collection, which is now housed in the Natural History Museum of Slovenia in Ljubljana.
Zoisite is a fascinating mineral, especially known for its violet-blue variety called Tanzanite and its rose-red variety called Thulite.
