Physical properties

Formation & geological history

Formed in granitic pegmatites and hydrothermal veins. It gets its distinctive color from minute amount of lead and water within the feldspar structure. Found in Precambrian to Cenozoic geological settings.

Uses & applications

Primarily used as a gemstone for jewelry (cabochons, beads) and as an ornamental stone in carvings. It is a popular specimen for mineral collectors due to its vibrant color.

Geological facts

Named after the Amazon River, though it is not actually found there. It was historically called 'Amazon Stone.' It is particularly famous for occurring with smoky quartz in Colorado locations like Pikes Peak.

Field identification & locations

Identify by its unique blue-green 'tiffany' color and the presence of fine, white, wavy lines (perthitic texture). Commonly found in Russia, Brazil, Madagascar, and the United States (Colorado and Virginia). Collectors should look for saturated color and minimal fractures.
