Hall Mine, Nye County, Nevada, U.S.A.

This specimen is the standard product for this American locality. Its monoclinic crystals are small (3/16" max. length) and prismatic, but showing radiating tendencies from several central points. They are a lavender color and transparent, and cover about 35% of the host rock, which seems to consist of massive Quartz and a variety of Feldspar, with tiny veins of Pyrite or some other sulfide. This is some very pretty stuff! Ah, yes, it fluoresces, too!

Though a relatively small specimen, this piece boasts large crystals. These Creedite prisms have a diamond-shaped cross-section, sloping termination and achieve a maximum length of almost 1/4"(6 mm)! The amount of definition and lack of damage are not common for crystals this size, especially on a small specimen. The crystals are a pale pink color with a hint of violet and are slightly transparent, being a bit foggy like rose quartz. They have a surprisingly shiny, vitreous luster. So much Creedite is infused in the host rock that it is difficult to define. The specimen is attached to a square acrylic base with a tacky putty. This is one of the nicest quality specimens of Creedite that I have seen for its size.

Hall Mine, Nye County, Nevada, U.S.A.

At least 20 Creedite cryastals of impressive size rest on this specimen. They have a prismatic form with a diamond-shaped cross-section and a steeply sloping termination. The largest of these crystals measure 5 x 3 x 2 mm. All are in excellent condition, though tere are some patches on the host rock where clusters have been crushed and broken. They all have a pale pink color, a vitreous luster, and are transparent. They rest on a host rock that looks as if it's made of alternating layers of quartz and some type of feldspar. The specimen is attached to an acrylic base with an adhesive putty.

At least 20 small Creedite crystals rest on the thin, pale brown crust of this thumbnail specimen. All are very small, not exceeding 0.1" (3 mm) in length, but they are in excellent condtion, showing very little damage. Their monoclinic prismatic form is excellent, and many of the crystals seem to be gathered in almost radiating clusters. All have a pale lavender coloration and a bright vitreous luster, and are transparent and partly clear, as many of them seem to possess a cloudy "core" that is surrounded by a clear "shell".

Hall Mine, Nye County, Nevada, U.S.A.

The dull gray-brown host rock of this thumbnail specimen is covered with a crust made up of at least 50 intergrown Creedite crystals. These crystals, though not exceeding 0.1" (3 mm) in length, are in excellent condition, showing almost no damage. Their monoclinic prismatic form is very well-defined, with sharp edges and clean faces that possess a vitreous luster (see the close-up image). All have the standard pale-lavender coloration of Creedite and are transparent and quite clear. The host rock is nondescript and is mostly covered by the Creedite druse.

Tonopah vicinity, Nye County, Nevada, U.S.A.

A crust of intergrown Creedite crystals coating a quartz and muscovite base make up this large thumbnail specimen. The crystals that make up the crust are mostly damaged, but several are still intact. They do not exceed 0.1" (3 mm) in length and have good monoclinic prismatic form, with well-defined edges and striated but clean faces that possess a pearly-to-vitreous luster. All have a pale lavender coloration and are transparent and quite clear.

Anaconda Mine, near Tonopah, Nye County, Nevada

A druse if many tiny Creedite prisms rests on the white quartz base of this large hand specimen. These crystals are in excellent condition, showing no damage, and appear to have excellent monoclinic bladed form, though they are so intergrown as to appear specular in a few areas. All have the standard lavender coloration and a bright pearly luster, and individual crystals are transparent and moderately clear- those that are "specular" are a deeper violet in color and are essentially translucent. The quartz base on which they rest contains some pyrite or other metallic sulfide in one area.

Hall Mine, near Tonopah, Nye County, Nevada, U.S.A.

This small thumbnail piece consists of a druse of small Creedite crystals that rests on a crumbly, pale brown base. These crystals reach lengths of 0.3" (8 mm) and are in very good condition- there is little damage present. Their monoclinic prismatic form is very good, and all have the pale lavender color and pearly-to-vitreous luster that are standard for the specie. The piece is affixed inside a plastic specimen box with a removable putty, but because of its delicate nature, it is probably wise not to try to remove it.

Anaconda Mine, near Tonopah, Nye County, Nevada, U.S.A.

About 20 Creedite prisms rest on the pale beige base of this large hand specimen. These crystals are in good condition, showing little damage, and are some of the largest that I have ever seen- they reach lengths of 0.5" (1.3 cm)! All show excellent monoclinic prismatic form and have the standard pale pink color and dull pearly luster of their specie. They are only dimly transparent at best, and most are cloudy. A small amount of some metallic sulfide is also scattered on the base.

Francisco Portillo, Santa Eulalia, Chihuahua, Mexico

Hundreds of tiny Creedites rest in hollows in the black base rock of this hand specimen. These crystals do not exceed 0.1" (4 mm) in length and are generally in very good condition - a small number of crystals are exposed and damaged or broken. All appear to show excellent monoclinic bladed form, and have a vitreous luster. They are colorless, as opposed to the pale-pink crystals found in Nevada, U.S.A., and are transparent and very clear. Some extend from a white, massive formation that rests on the base rock- I do not know what this material is.

Anaconda Mine, near Tonopah, Nye County, Nevada, U.S.A.

This flat cabinet specimen is made up almost entirely of compact, acicular and crystalline, radiating Creedite. Though many of the crystals are noticeably crushed, there are still hundreds that are intact and in excellent condition. These crystals have excellent monoclinic prismatic form. Some of them show a pale pink color which is common for specimens from this locality and the standard vitreous luster, but most are nearly colorless and have a dull pearly luster, likely due to weathering of some sort. The more massive material is dull in luster and has a pale violet-blue coloration. Only a small amount of a pale gray host rock is present.

This lovely cabinet piece consists of a few veins of crystalline Creedite that extend through a pale brown host rock. These veins are made up of compact, sometimes radiating Creedite crystals that are generally in excellent condition and reach lengths of nearly 0.3" (8 mm). All have very good monoclinic prismatic form and show the standard pale violet color and vitreous luster of their specie. They are generally transparent and show dim to moderate violet fluorescence. Some quartz and a small amount of pyrite are also present on the host rock, which is affixed to a square acrylic base with a removable putty.

This rather odd specimen contains two small clusters of warped, apparently incomplete Creedites. They are in excellent condition, showing no fresh damage, and do not exceed 0.2-0.3" (5-8 mm) in length. All have highly warped, nearly unrecognizable monoclinic prismatic form that appears to have been caused by intense erosion, probably by water. They are essentially colorless, show a pearly luster, and are transparent and quite clear. They are rather difficult to isolate amid scores of what appear to be selenite blades. The Creedites glow violet under shortwave ultraviolet light, however. These blades look very much like selenite, including having a rhombic cross-section, but they are too hard. This made me consider barite, but the form does not seem to correspond to the orthorhombic form of barite. All are transparent, quite clear and tend to be colorless, but many have rusty inclusions. Their luster is bright and vitreous, and their prism faces show little striation.

A crust of intergrown and clustered Creedite prisms rests on the pale brown base of this cabinet specimen. These crystals are generally in good condition, showing moderate damage, and reach lengths of 0.3" (8 mm). All have excellent monoclinic form and show the classic pale violet color and vitreous luster. All are likewise transparent and quite clear. A large amount of quartz and a small amount of pyrite make up part of the base rock, which is affixed to an acrylic base with an adhesive putty.
