Hemimorphite is found in many localities worldwide, though most only produce microcrystal
s of this mineral. However, there are many exceptional localities though that have provided excellent mineral specimens. In Europe, some of the earliest occurrences of Hemimorphite were at Vieille Montagne, Kelmis, Belgium. Blue globular
and white crystallized forms of this mineral are found in Germs-sur-l'Oussouet, Lourdes, France; and at the Sa Duchessa Mine, Domusnovas, Sardinia, Italy. Colorless and white Hemimorphite crystals, sometimes associated with Wulfenite
, have come from Bleiberg, Carinthia, Austria; and white crystal fans from Lavrion District, Attiki, Greece.
China has recently been producing some outstanding globular forms Hemimorphite with a deep, neon blue color. The most notable localities are Dulong and Wenshan, Yunnan Province. In Iran, nice white crystals are found in the Qaleh-Zari Mine, Nehbandan.
In Africa, pale blue, spiky Hemimorphite crystals come from the Skorpion Mine, Rosh Pinah, Namibia; and light blue rounded aggregates are found in M'Fouati and Mindouli, Congo.
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.
In the U.S., globular masses of Hemimorphite are well-known from the Sterling Hill Mine, Ogdensburg, Sussex Co., New Jersey. This locality has produced rounded white aggregates and sparkling drusy crystals. Tan and yellow Hemimorphite has come from Granby, Newton Co., Missouri; and Joplin, Jasper Co., Missouri, often as epimorphs and coatings.
Very large, white and colorless Hemimorphite crystals come from the Summit Mine, Radersburg District, Broadwater Co., Montana; and dense white crystal aggregates from Leadville District, Lake Co., Colorado. The 79 Mine near Hayden, Gila Co., Arizona, has produced Hemimorphite in beautiful, lightly-colored blue and greenish rounded aggregates.
