Discover Svabite from Långban Mine, Värmland County, Sweden, a calcium arsenate mineral belonging to the apatite supergroup.

Tested by GeoFossils, these specimens display orange fluorescence under Short Wave (SW) UV. Each piece has been individually photographed and numbered, allowing you to select the exact specimen you wish to receive.

Långban is an important historic mineral locality, recognised for its unusually diverse mineralogy and numerous type-locality species. This provenance, together with Svabite's mineral chemistry and fluorescent response, is of particular interest to collectors of Swedish and fluorescent minerals.

Choosing your specimen

Six specimens are available, numbered 162–167. Select your preferred number from the variant menu to receive the corresponding photographed specimen.

UV fluorescence

The orange response has been observed by GeoFossils on each specimen in this collection. Fluorescence can vary in intensity according to the specimen, UV lamp output, ambient light and viewing conditions.

Scientific information

Formation & mineralogy

Svabite is the arsenate analogue of fluorapatite and the fluorine-dominant analogue of johnbaumite. Its close structural relationship with other members of the apatite group means that reliable identification depends on mineral chemistry rather than appearance alone.

Locality & collector significance

Långban Mine is one of Sweden's best-known historic mineral localities and is documented as the type locality for numerous mineral species. Its unusual mineral diversity has made material from Långban significant to collectors interested in Swedish mineralogy and systematic collections.

Viewing your UV mineral

For the clearest fluorescence, view the specimen in a dark environment using an appropriate Short Wave mineral UV lamp.

Always follow the UV equipment manufacturer's instructions and avoid looking directly into the UV light source.

Care instructions

Handle Svabite carefully and store it separately from harder minerals to reduce the risk of scratching or chipping. Remove loose dust with a soft, dry brush and avoid abrasive cleaning methods or harsh household chemicals.

Frequently asked questions

What colour does this Svabite fluoresce?
GeoFossils has observed orange fluorescence under Short Wave (SW) UV across these specimens.

Where is this Svabite from?
The specimens are from Långban Mine, Värmland County, Sweden.

Will I receive the specimen shown?

Please note

You will receive the exact specimen selected from the variant menu and shown in the corresponding photographs. Fluorescent colours may appear slightly different in person because lamp output, ambient lighting, camera settings and viewing conditions can affect their appearance.
