Microcline is one of the most common feldspar minerals. It can be colorless, white, cream to pale yellow, salmon pink to red, or bright green to blue-green. Microcline forms short prismatic or tabular crystals that are often of considerable size: single crystals can weigh several tons and reach yards in length. Crystals are often multiply twinned, with two sets of fine lines at right angles to each other. This gives a plaid effect that is unique to microcline among the feldspars.  The nice patch of Quartz crystals makes this a spectacular piece. 

This is a quality specimen that would be a beautiful addition to any new or existing rock collection.

This is an attractive specimen consisting of natural pale gray transparent crystals of Calcite on a green crystal matrix from Morocco.  Very beautiful material.

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.

This is a large sparkly cluster of beautiful multi-colored bladed barite and some Cerussite crystals.  Barite crystal formations grow in parallel sheets that almost appear fibrous. It is well-known for its great range of colors and varied crystal forms and habits. Cerussite is commonly known as white lead and is an important ore mineral.  It consists of lead carbonate which crystallizes in the orthorhombic system.  Its color will vary depending on the composition and structure, with colorless, white, grey and green tinted, being the most common colors of crystals found.

Celestite, also known as celestine, typically ranges in color from light blue to pale blue, though it can also be colorless, white, or shades of yellow and pink.  Celestite is a strontium sulfate mineral which crystallizes in the orthorhombic crystal system, typically forming well-defined, prismatic crystals.  This celestite specimen is a nice example of a prismatic crystal form.

Celestite is often associated with calming energy and is believed to aid in meditation and spiritual development. It is said to promote mental clarity and enhance communication with higher realms.

Cubic and crystallized Pyrite matrix with Marmatite 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.

This top specimen is in very good condition. Would be a beautiful addition to any new or existing collection.

This is a superb terminated Peruvian quartz crystals. This top specimen is in very good condition and would be a beautiful addition to any new or existing collection.

Quartz crystals are among the most abundant and well-known minerals on Earth. It belongs to the hexagonal crystal system, and typically forms six-sided prismatic crystals with a pointed termination. Its crystals can be colorless or exhibit a wide range of colors. The color variations are often due to the presence of impurities or trace elements during the crystal's formation. Quartz is transparent to translucent. 

Quartz is considered a “master healer.” It's said to amplify energy by absorbing, storing, releasing, and regulating it. It's also said to aid concentration and memory. Physically, clear crystals are claimed to help stimulate the immune system and balance out your entire body.

Quartz is also said to be a power gemstone that harmonizes and balances; enhancing energy and thoughts as well as purifying the spiritual, mental and physical. Quartz is associated with the crown chakra.
