Rare snow-white, nearly acicular Strontianite crystals in radiating clusters or "balls," on a Calcite matrix
Strontianite (SrCO3) is a mineral consisting of strontium carbonate, named after the village of Strontian, Lochaber, Scotland, where it was first discovered. This mineral is white, greenish, or yellowish in color, usually occurring in fibrous massive forms, but sometimes in prismatic crystals. It is an important raw material for the extraction of strontium (From Wikipedia, the free encyclopedia).

Brazil's Diamantina region in north-central Minas Gerais was a major source for gold and diamonds in the early 1700s, when the Portuguese controlled the region.
Goethite, named after the German polymath Johann Wolfgang von Goethe, is an iron bearing oxide mineral found in soil and other low temperature environments
(From Wikipedia, the free encyclopedia).
Multi-colored iridescence transforms this usually unattractive Goethite mineral into an eye catching specimen. The Goethite has grown over Rutile.
Beautiful 3.7 lb. polished hunk of Malachite that has formed about a dozed "bullseyes." Also some small areas of light blue Chrysocolla. These are highly sought after decorative specimens.

Lustrous lavender colored Smithsonite. The distinct mineral Smithsonite was first described in 1832 and named for British chemist and mineralogist, James Smithson (1754-1829), whose estate financed the Smithsonian Institution.

Spessartine is one of the aluminum garnets, along with almandine and pyrope forming the "pyralspite" group. Spessartine is an uncommon garnet. It ranges in color from red-brown to yellow-brown.
Numerous dark amber colored Spessartine Garnets with minor Smoky Quartz on matrix.
Metaphysical Properties: Desert rose helps disperse self-imposed programs that are running too long as well as creates inner peace. It can be used to strengthen affirmations of purpose.
Interesting "mouse ear" shaped desert rose formation. When Gypsum (var. Selenite) crystals form in sandy areas, the crystals trap sand and become browner in color.  Selenite crystals with sand inclusions forming in a rosette shape are called "desert roses." 
The Blanchard mine is probably the best collecting location in New Mexico. World class specimens of fluorite, linarite, brochantite, and barite have been found . Galena was the primary ore  at the mine and is ubiquitous. Other minerals found include cerussite, anglesite, wulfenite, jarosite, gypsum, smithsonite, hemimorphite, and many others.


Beautiful blue Fluorite cubes on matrix, the color being unique to the mine.
Heavy, solid plate of golden Chalcopyrite with a nice partial covering of white Calcite crystals.

Terrific pseudomorph of light brown Siderite after Calcite.

Siderite is a mineral composed of iron carbonate FeCO3. It takes its name from the Greek word sideros, “iron”. It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus.
In geology, a pseudomorph is a mineral compound resulting from a substitution process in which the appearance and dimensions remain constant, but the mineral which makes up the chief component of the compound is replaced by another. The name literally means False Form.

Three kinds of pseudomorph exist:

A paramorph (also called allomorph) is a mineral changed on the molecular level only. It has the same chemical composition, but with a different structure. The mineral looks identical to the original unaltered form. This occurs, as an example, in the aragonite to calcite change.

An infiltration pseudomorph is a pseudomorph in which one mineral or other material is replaced by another. The original shape of the mineral remains unchanged, but color, hardness, and other properties change to those of the replacing mineral. An example of this process (also called substitution) is the replacement of wood by silica (quartz or opal) to form petrified wood in which the substitution may be so perfect as to retain the original cellular structure of the wood. An example of mineral-to-mineral substitution is replacement of aragonite twin crystals by native copper, as occurs at Corococo, Bolivia.

A variety of infiltration or substitution pseudomorphism is called alteration, in which only partial replacement occurs. This happens typically when a mineral of one composition changes by chemical reaction to another of similar composition, retaining the original crystalline shape. An example is a change from galena, lead sulfide, to anglesite, lead sulfate. The resulting pseudomorph may contain an unaltered core of galena surrounded by anglesite that has the cubic crystal shape of galena.

An incrustation pseudomorph results from a process by which a mineral is coated by another and the encased mineral dissolves. The encasing mineral remains intact, and retains the shape of the original mineral or material. Alternatively, another mineral may fill the space (the mold) previously occupied by some other mineral or material

Woomera is a famous outback township which, from the 1940s, was the centre of Australian and British rocket launching experiments
Located 486 km north of Adelaide and positioned some 165 m above sea level, Woomera is a purpose built town designed by the Long Range Weapons Board of Administration to provide an isolated experimental ground for testing rockets. It is located in the middle of a desert terrain where the average annual rainfall is only 190 mm.

Hardin County is located in the scenic Shawnee Hills of southeast Illinois. With the Ohio River serving as a main artery of transportation, the county served as a gateway to Illinois during the late 1700s and 1800s. Pioneers passed through these lands on their way west. Many stayed to settle in beautiful Southern Illinois.

Six perfect Scheelite light orange, somewhat gemmy, octahedrons to 3 cm in size nicely arranged on a Muscovite covered matrix. The crystals are undamaged. Sawn around the edges.

Scheelite is named in honor of the Swedish chemist K. W. Scheele who analyzed the tungsten in the mineral.
