World of Rocks & Minerals

Learn about the properties of different rocks and minerals in this kit containing more than 80 specimens from around the world. With this kit, you can examine rocks and minerals at up to 250x magnification using a USB 2.0 digital microscope and observe some minerals change color under a blacklight.

NOTE: This rock kit contains galena, a source of lead. Skin contact with galena is not dangerous; however, to avoid potential digestion, always wash hands after handling.


Fluorescent Mineral Kit

Learn about fluorescence the fun way-by viewing glow-in-the-dark rocks! This kit comes with six 1.5"-2" mineral specimens that fluoresce under the black light (longwave UV) flashlight that's included. This kit is recommended for ages 8+

  • A boxed set of six 1.5"-2" fluorescent mineral specimens
  • A 6" black light that emits longwave ultraviolet light
  • The Story of Fluorescence by Harry C. Wain booklet
  • Our special instructions that teach about ultraviolet light, fluorescent minerals, and include three extra UV light activities

NOTE: UV light is the part of the sun light that causes sunburns. Never look directly at UV bulbs and wear UV filtering goggles if using for extended periods.

Minerals included in this set and color under UV light:

  • Aragonite – yellowish-brown
  • Hackmanite – orange
  • Calcite – pale yellow
  • Flourite – purple, blue
  • Resinous coal – blue, green, gold
  • Scapolite (Wernerite) – yellow


Tektite Sample – Extraterrestrial impact Stone

A tektite is a small, naturally glossy rock that is made from a meteorite impact. More specifically, tektites are made of black, gray, brown, or green (ex. moldavite is a green tektite) natural gasses. They are melted during meteorite impacts and essentially splashed into Earth's upper atmosphere, where they then harden, cool, and fall to the Earth's surface.

Tektites are only found in certain areas around the world. They can be found in what are called strewn fields, simply defined as regions on Earth's surface within which tektites of similar origin or age are found.


Geode Samples

Different types of geodes form when mineral deposits build up inside volcanic or sedimentary rock "bubbles." Although they look like ordinary igneous or sedimentary rocks, geodes are often full of a variety of crystals.


Plugable USB 2.0 Digital Microscope

  • 2.0 Megapixels, up to 250x magnification (Note: Final magnification corresponds to monitor size)
  • Uses a webcam chipset and sensor to support a nearly any operating system and standard webcam software
