Fluorescence occurs when a mineral absorbs ultraviolet radiation and immediately re-emits visible light. This phenomenon transforms ordinary-looking specimens into vivid displays of color under UV lamps. There is a decent amount of mineral collectors, who specialize on UV active minerals.
The Munich Show finally returned in the 2024 in its full shape and size as before Covid. There was plenty of new minerals, plenty of interesting people and friends, and vast amount of deals available.
Natrolite is a common sodium zeolite, forming highly aesthetic and fragile crystals. It has also important industrial use in mineral filters and absorbers.
Matthew (Matthäus) Parshchikov is a young mineral collector, geosciences student, and photographer from Cologne, Germany.

Spodumene is an uncommon lithium silicate and one of the precious lithium ores. It produces nice crystals as well as popular and colorful gem material.
Ankerite is interesting and surprisingly uncommon carbonate, mostly limited to metasomatic rocks and hydrothermal veins. It can form outstanding crystals and clusters.
The Munich Show 2023 was back to the standard. Lot of new and outstanding mineral specimens, good bargains and many new publications. The main show exhibition was truly magnificent, with outstanding specimens and their paintings.
Minerals of the tourmaline supergroup occur in a wide range of colors and form spectacular crystals, which makes them highly popular among mineral collectors. Tourmaline is also important geochemical and petrological indicator.
Marcasite is very common mineral, but it is often ignored by mineral collectors. Despite its nice crystal forms, it lacks the luster of some other sulfides and its quite brittle. Its infamous instability in just slightly wet air does not help its popularity either.
Native sulphur is one of the few non-metallic and naturally occurring native elements. Despite huge drop of its industrial use, the native sulphur is still mined today. It can form highly aesthetic bright yellow crystals, which are very popular among mineral collectors.
Staurolite belongs to the scientifically important but otherwise quite overlooked minerals. It is not very popular among mineral collectors, as most of the specimens looks similar to each other. Also industrial application of staurolite is very limited.
