This is a stunning specimen of calcite cubes on mordenite druse. The crystals are well defined and look beautiful together.
Calcite is found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble.
Mordenite was first described in 1864 by Henry How. He named it after the small community of Morden, Nova Scotia, Canada, along the Bay of Fundy, where it was first found. It is one of the most abundant zeolites and is found in volcanic rock such as rhyolite, andesite, and basalt. It is associated with other zeolites such as stilbite and heulandite.

Apophyllite, Stilbite and Calcite on Chalcedony Druse | 2.46 kg | Jalgaon, India
Apophyllite, Stilbite and Calcite on Chalcedony Druse | 2.46 kg | Jalgaon, India
This is a beautiful combination of Apophyllite, Stilbite and Calcite on Chalcedony Druse. It is a large specimen at over 2 kg and has many double terminated crystals.
Stilbite is a zeolite mineral appreciated for its delicate crystal formations and pastel hues, ranging from colorless to white, yellow, pink, and peach. It forms distinctive tabular crystals with a bowtie or butterfly shape and exhibits a vitreous to pearly luster.
One of the distinguishing features of apophyllite is its ability to form well-defined crystals with a pyramid-like shape. These crystals often exhibit a prismatic or pseudo-cubic habit and have a vitreous luster. Apophyllite is transparent to translucent and is commonly found in colorless or white varieties, although it can also occur in shades of green, pink, yellow, or brown.
Chalcedony is a microcrystalline Quartz found in many different colours and patterns. It has a number of crystals grouped under it many of which are very familiar, including Agate, Carnelian, Chrysoprase, Aventurine, Jasper and Onyx.

Kyanite is a silicate mineral with the chemical formula Al2SiO5. It's known to be one of the most attractive natural minerals in the world, frequently found with lustrous blue bladed crystals, with the intensity of color varying by location of extraction. Kyanite regularly forms fibrous, radiating crystals, as well as flattened and tabular. Some crystals form with white striations, color bands, and even multi-colored crystals, though typically found with a deep blue streak running down the middle.

Green Apophyllite Crystal on Acicular Scolecite matrix | 964 gr | Panvel, India
Green Apophyllite Crystal on Acicular Scolecite matrix | 964 gr | Panvel, India
Apophyllite almost always forms good crystals of two major types. The favorite crystal habit is the rectangular prism capped by a steep four sided pyramid. A doubly terminated crystal is exceptionally special. The faces of the pyramids are rotated 45 degrees with respect to the prism faces and so plunge down into the prism edges. This produces a diamond-shaped pyramidal face instead of a typical triangular pyramid face. The shape is an extraordinary example of tetragonal crystal form. Although normally colorless or white, colored examples of apophyllite are always treasured. Some crystals of apophyllite are cut as gems, but are mostly just for the collectors.
Scolecite forms as vertically striated, thin, prismatic crystals. Scolecite may also occur as radiating fibrous masses. The colour may be white, yellowish, or colourless. It is a transparent to translucent mineral, and it has a vitreous to silky luster.
This is an absolutely stunning piece!

This is a specimen of Star Mica or Muscovite and Quartz cluster. These clusters show crystals that grow in sheets or book formations. It is silvery gold with good transparency when held up to the light. The name Muscovite comes from the term Muscovy Glass which was a name for the thick sheets of Mica used as a substitute for glass Russia. The name Mica is derived from the Greek word that means to split.
On this nice specimen, the matrix faces are covered with beautiful golden yellow point stars of muscovite mica, a typical shape for this rare mica formation. The stars are the result of twinning; the points show a bit of wear but this does not detract from the beauty of such a piece.

Cubic and crystallized pyrite matrix with Marmatite and Quartz crystal cluster.
Some of the more important Colorado localities for specimens of well-crystallized pyrite include mines at cli- max, Gilman, Leadville, Rico, Ouray, Telluride, Creede, Alicante, Alice, and State Bridge. Specimens from each of these localities often have distinctive crystal habits and mineral associations. The Eagle mine is probably best known for its pyritohedral Pyrite specimens. This cluster is a good representative Eagle mine Pyrite showing typical striated pyritohedra with sharp, lustrous faces plus some Marmatite opaque black iron-rich crystals.
