Amazonite Crystal

About

Amazonite Crystal — Teal Feldspar from the World's Great Pegmatites Amazonite is the blue-green variety of microcline, a potassium feldspar that crystallizes in coarse-grained granite pegmatites — slow-cooling igneous bodies where large, well-formed crystals have time to develop. Its distinctive teal color, sitting somewhere between turquoise and jade, comes from trace amounts of lead combined with water bound within the crystal lattice. Mohs hardness: 6 to 6.5. The stone is named after the Amazon River, though no confirmed deposits have ever been documented there — the name attached from early trade routes long before modern mineralogy could verify sources. The most celebrated amazonite locality is Colorado's Pikes Peak batholith, where blue-green crystals grow intergrown with smoky quartz in some of the most iconic American mineral combinations. Major polished material comes from Brazil and Madagascar , where the color tends toward deeper teal. Russia's Ilmen Mountains produced the specimens that first made amazonite famous in European collections in the 18th century. A genuine hallmark of natural material: fine white albite streaks or a subtle grid-like shimmer running through the color — exsolution lamellae that separated from the feldspar as it cooled. Dyed imitations show uniform color with no internal structure. Every specimen here is hand-selected and individually photographed.

Amazonite is a blue-green variety of microcline feldspar (KAlSi3O8) that forms in granite pegmatites. The main commercial sources are Brazil, Madagascar, and Colorado (Pikes Peak area). Despite its name, no deposits have been confirmed along the Amazon River. How can I tell if amazonite
