Terlingua-type calcite shows a similar response to UV light compared to true Terlingua calcite, from the Terlingua, Texas, area. True...

A large and pretty calcite specimen from the Taolin Mine, Linxiang County, Hunan, China. The calcite glows a bright red in SW and a much...

This is a single, colorless calcite crystal from one of the lead mines that used to operate in Shullsburg, Wisconsin. Under UV, this...

Wheat sheaf bundles of parallel growth calcite crystals on a yellow/brown fluorite matrix, from Cave-In-Rock, Hardin County, Illinois. ...

This is a large cluster of transparent, modified rhombohedral calcite crystals on limestone matrix. It was collected in 2016 from the...

This is a spectacular and unique fluorescent specimen that has a lot going on under every UV wavelength. It perhaps shows the greatest...

Terlingua calcite is one of the most spectacular and beautiful fluorescent minerals due to its bright, multi-colored, multi-wave,...

It has been reported that crystals of sulfur from Maybee, Michigan, occasionally show weak yellow fluorescence under UV (Robbins,...

This calcite and hydrozincite combo comes from an old Belgian lead/zinc mine near Plombières, Liège province, Belgium. The locality is no...

Very sharp calcite needles that fluoresce a stong greenish white with an equally strong phosphorescence. Clearly some polycyclic aromatic...

You can hardly distinguish between calcite and swedenborgite in white light. In SW-UV they couldn't be more different. Micheal Gaft, H....

From Weardale, Durham, UK, comes this lovely combo. Under midwave UV you get the fluorescence of both the fluorite and the calcite....

On less than 1 cm² we find these three minerals. Calcite fluoresces red, aragonite fluoresces greenish white, cerussite is intergrown...

This specimen is an excellent example of building with the materials at hand. It is a piece of concrete, collected from the Trotter...

If I had to pick the top five fluorescent localities in the world I would pick the Hogan claim in AZ as one. They are bright and...

Tabular calcite crystals and small scheelite octahedrons on limestone matrix, from the Ophir Hill Mine, Ophir, Tooele County, Utah. At...

This milky white calcite cleavage fragment was collected in 2016 from a roadcut along Indiana State Route 37 in Bedford, Indiana, very...

This is a large specimen of milky white to light pink, stacked, poker chip calcite crystals on a bed of massive pink calcite, from Russia....

A red/brown, somewhat rhombohedral, piece of nearly pure willemite, with minor calcite. This red variety of willemite contains manganese...

Aragonite "lightning bolts" fluoresce bright blue/white on this spectacular specimen from the Long Lake Zinc Mine, Olden Township, near...
