Labradorite Pricing, Jewelry Details, and Insights into Its Worth
Labradorite, a feldspar mineral known for its distinctive optical effect called labradorescence, is a popular choice among gemstone enthusiasts. This unique property causes flashes of blue, green, gold, or multicolor iridescence, best seen when the stone is tilted, revealing "frozen auroras" of color against a gray to black base [1].
Common sources of labradorite include the Labrador Peninsula in Canada, Madagascar, Finland, Russia, and India. However, Oregon labradorite, often referred to as "Oregon Sunstone" or specifically Oregon labradorite, stands out for its richer, more vibrant flashes and unique inclusions linked to the local geology in Oregon [5].
Oregon stones often show a vivid color range, including fiery oranges and reds beyond the traditional blue and green flashes. They are appreciated for their quality of labradorescence, sometimes offering a more intense range of hues [5]. Oregon labradorite also often shows excellent polish and symmetry, which highlights its color properties.
Despite the unique characteristics of Oregon labradorite, its fundamental mineralogical properties align with labradorite worldwide. The core chemical formula (Na,Ca)(Al,Si)4O8 and physical properties such as hardness (6–6.5 Mohs), cleavage, crystal system (triclinic), and the labradorescence effect remain consistent across sources [1].
While the exact scientific data like differences in chemical composition, crystal system, or precise optical characteristics specific to Oregon labradorite compared to other locations is not detailed in the given search results, further gemological analysis specific to Oregon specimens would be needed for a more thorough comparison.
In addition to its use in jewelry, labradorite with Schiller is also a component of many dark-colored igneous rocks used in building and construction as facing materials [1]. Faceted labradorite makes a handsome jewelry stone, but its cleavage should be minded due to its hardness similar to moonstone or other feldspars.

Labradorite, originating from Oregon, is highly sought after in the fashion-and-beauty industry for its richer and more vibrant flashes of colors, often showcasing fiery oranges and reds that surpass traditional blue and green hues. These gemstones, appreciated for their quality of labradorescence, are commonly used in jewelry as jewelry stones.
Owing to its unique inclusions linked to the local geology in Oregon, labradorite can also be found in home-and-garden applications as a component of many dark-colored igneous rocks used in building and construction as facing materials.
