This colorful, engaging rock collection will teach you more about diamonds, gems, and their connection to kimberlite, lamproite & diatremes. We have selected six specimens, a few from premier geological sites, to help explain the mechanisms involved in how diamonds are created and transported to the surface. Our information guide features diamond locations, history, mining, and details about each specimen. The photo for this rock collection is of the famous "Big Hole" in South Africa, one of Earth's premier diamond mines.

The rock specimens in this collection are:

"Big Hole" Kimberlite from Kimberley, South Africa.
Ferris Kimberlite from Albany Co., Wyoming.
Lake Ellen Kimberlite from Iron Co., Michigan.
Ville-Marie Kimberlite from Quebec, Canada.
Mule Ear Diatreme from San Juan Co., Utah.
Crater of Diamonds State Park Lamproite from Arkansas.

Diamonds are formed deep within our planet's mantle and forced to the surface during a rare volcanic eruption. This type of volcanic eruption is one of nature's most rapid and violent events. The hardness of diamonds helps them endure the rigors of such a tumultuous journey.

Their value has made them immortal celebrities on the world stage, with names to fit their reputation, such as Hope, Moon of Baroda, Oppenheimer Blue, Koh-i-Noor, The Enigma, Great Star of Africa, and many more! Their worth depends on the carat, clarity, color, and cut. Their colors are as exotic as their names, ranging from red, blue, pink, green, purple, violet, gray, brown, orange, yellow, white, and even black.

We have selected six specimens, a few from premier geological sites, to describe the mechanisms of how diamonds are created and transported to the surface. There are three types of volcanic pipes that carry diamonds to the surface: kimberlite, lamproite, & diatremes. Our information guide includes diamond mine locations, history, and details about each specimen.

The rock specimens are sized to fit into a 7/8" circle. The rock sizes are .75"L X 3/8 to 5/8" W and 3/8 to 1/2" D.

The diamond kimberlite, lamproite and diatreme rock collection plexiglass case size is 8 1/4" L X 7" W X 5/8" D.

Each collection features similar yet different specimens.
