Hemimorphite Specimen #30
- Hemimorphite Specimen #30
- Hemimorphite is an ore of zinc in zinc deposits. It is also an important mineral for collectors, especially when well-crystallized and in globular blue forms. Hemimorphite is also used as a collectors gemstone, with the blue forms polished into cabochons for collectors of rare gemstones.
- Hemimorphite, a component of Calamine. It is a sorosilicate mineral which has been historically mined from the upper parts of zinc and lead ores, chiefly associated with Smithsonite. They were assumed to be the same mineral and both were classed under the same name of Calamine.
- Hemimorphite is a unique mineral, with different crystal terminations on each side of a single crystal. This habit is responsible for Hemimorphite's name, from the Greek hemi, meaning "half" and morph, meaning shape. Although this habit is very common among Hemimorphite crystals, its visibility is usually obscured by one end of a crystal being attached to the matrix.
- Measures approx. 5 1/4" x 4 1/4" x 1 1/2"
- Mexico is probably the most prolific country when it comes to collectible specimen production of Hemimorphite. The famous Ojuela Mine in Mapimi, Durango is one of the most prolific Hemimorphite localites, forming well-shaped crystals on a Limonite matrix. Very large white crystals and fans have been found at Santa Eulalia, Chihuahua; and toothpaste-blue botryoidal Hemimorphite has come from the Santo Niño Mine, Santa María del Oro, Durango.
