100 years – 100 Objects: Azurite

The Houston Museum of Natural Science was founded in 1909 - meaning that the curators of the Houston Museum of Natural Science have been collecting and preserving natural and cultural treasures for a hundred years now. For this yearlong series, our current curators have chosen one hundred exceptional objects from the Museum’s immense storehouse of specimens and artifacts—one for each year of our history. Check back here frequently to learn more about this diverse selection of behind-the-scenes curiosities—we will post the image and description of a new object every few days.

This description is from Joel, the Museum’s President and Curator of Gems and Minerals. He’s chosen spectacular objects from the Museum’s mineralogy collection, which includes some of the most rare and fascinating mineral specimens in the world, that we’ll be sharing here – and at 100.hmns.org- throughout the year.

Azurite
Tsumeb Mine, Tsumeb, Namibia

 The Tsumeb mine has produced the world’s finest azurite crystals, of which this large 11-cm crystal group on green smithsonite is one of the best examples. The highly lustrous, elongated crystals with perfect terminations, on a contrasting base, admirably fulfill the requirements of connoisseurship.

main-elbaite-on-quartzTourmaline Queen Mine, San Diego County, California.
North America has produced some extraordinarily beautiful specimens of elbaite, a member of the tourmaline group, but the most admired are the bright red-pink crystals with blue caps found in 1972 at the Tourmaline Queen mine. The 24-cm example pictured here is the finest of the 33 major specimens recovered and is therefore the finest North American tourmaline. The lustrous, lusciously colored, undamaged pair of crystals at the top grow from an undamaged quartz crystal and are accompanied by smaller tourmaline crystals. It has been nicknamed “The Rabbit Ears.”

Tsumeb Mine, Tsumeb, Namibia.

Among the most beautiful of all smithsonite specimens found anywhere in the world are the apple-green to emerald-green crystals from Tsumeb. The color comes from trace amounts of copper and is so distinctive that cuprian smithsonite from Tsumeb was, for a time, given its own name, “herrerite” (named for the local Herrero tribe) before it was proven to be a variety of smithsonite.

The extraordinary 8.1-cm example pictured here is perhaps the finest known example of the variety, showing deep color, unusual transparency, brilliant luster, interesting crystal shape, and a fine, large grouping of crystals.

Sweet Home Mine near Alma, Colorado.

The superb 10-cm rhodochrosite crystal on matrix pictured here, known as “The Alma Queen,” is among the most famous specimens in all of mineralogy. It is the best specimen recovered from a pocket found in 1965 by John Soules and Warren Good. The exceptionally large, rich red-colored crystals perched on a crystallized matrix of quartz and tetrahedrite combine to create a level of sculptural composition and aesthetic beauty that make this one of the world’s truly great mineral specimens. Since its discovery, it has attained legendary status as a “Mona Lisa” of the mineral world – it is widely regarded as the finest example of rhodochrosite known – and among knowledgeable collectors and connoisseurs, it is considered to be the finest mineral specimen of any kind ever found.
