5.2" Amazonite Crystal Cluster with Quartz - Colorado

This is a lovely, teal blue amazonite crystal cluster mined from the 10 Percenter Claim in Park County, Colorado. Quartz crystals can be found along the edge, in small cavities and across the underside of this specimen. Another exciting feature of this crystal association is the octahedral fluorite crystals along the underside of the specimen. The largest amazonite crystal is .8" wide.

Comes with an acrylic display stand.

Amazonite is a green variety of microcline feldspar that is the state mineral of Colorado. It has recently received a lot of attention for its prominence on the reality show, “Prospectors” which follows several groups of Colorado mineral miners. In fact, most of our amazonite is sourced from some of the prospectors on the show. High quality amazonite crystals are found at several locations in Colorado, often in vugs associated with smoky quartz.

The name comes from the Amazon River, where it was thought Amazonite was originally found, though it’s now thought doubtful that it occurs in the region. For years it was thought that the green color was due to copper content, but we now know that it’s due to very small quantities of lead present in the mineral.

Silicon Dioxide, also known as SiO2 or Quartz, is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich, hot watery solutions called hydrothermal environments, at temperatures between 100°C and 450°C, and usually under very high pressure. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountains forming, and can be hundreds of millions of years old.

Fluorite is a halide mineral comprised of calcium and fluorine, CaF2. The word fluorite is from the Latin fluo-, which means "to flow". In 1852 fluorite gave its name to the phenomenon known as fluorescence, or the property of fluorite to glow a different color depending upon the bandwidth of the ultraviolet light it is exposed to. Fluorite occurs commonly in cubic, octahedral and dodecahedral crystals in many different colors. These colors range from colorless and completely transparent to yellow, green, blue, purple, pink or black. Purples and greens tend to be the most common colors seen.
