Eastern Hemisphere Rocks

Fluorescent Rocks from Langban, Sweden; Rogerly Mine, England; Shigar Valley, Pakistan; and La Grasta Mine, Italy.

Langban, Sweden

Langban rocks are among the brightest fluorescent specimens, often shining vividly against a dark or black background. These hand-sized treasures are impressive with:

• Calcite: bright red
• Svabite: bright yellow
• Dolomite: bright pink-red
• Willemite: green
• Berzillite: blue

These fluoresce beautifully under short-wave ultraviolet light.

Rogerly Mine, England

The Rogerly Mine features large, zoned, translucent fluorite specimens. These beauties shine in daylight and glow a bright blue under both long and short-wave ultraviolet light.

This double hand-sized specimen is a favorite.

- Fluorite

Shingar Valley, Pakistan

Apatite crystals fluoresce yellow against a dark backdrop of quartz and schorl tourmaline crystals. This fist-sized specimen is stunning in both natural and short-wave ultraviolet light.

La Grasta Mine, Italy

This aragonite specimen is a classic from a historic locale. The fluorescent colors are vibrant and change subtly across the specimen, creating an illusion of translucency and zoning not visible in natural light.

Under different UV wavelengths, the fluorescent colors change dramatically:

• Natural light: translucent white
• Long wave: bright pink
• Mid wave: lavender
• Short wave: lilac
• Phosphorescence: soft aqua-green

A very unusual and beautiful specimen.

- Aragonite Crystals

Malawi

A zircon crystal from the Rift Mineral Province. This one’s big and is one of the oldest rocks in the world. It has a nice heft and is a fluorescent classic.
