Oligoclase

Oligoclase is a plagioclase (feldspar) mineral prized by collectors and jewelers, especially its enchanting variety, Sunstone. While oligoclase itself can be found in more modest shades of white, gray, yellowish, or greenish with a vitreous luster, it is Sunstone that captivates the imagination with its unique optical effect, aventurescence. This enchanting, sparkling, sun-like shine is caused by small, lamellar inclusions of hematite, goethite, or copper within the crystal.

The color range of Sunstone is typically warm, ranging from golden yellow and orange to reddish and brown, sometimes with green hues. Oligoclase forms in igneous and metamorphic rocks, often found alongside other feldspars, such as labradorite.

The main deposits that yield high-quality Sunstone are located in India, the USA (Oregon), Norway, Canada and Tanzania. Sunstone is traditionally associated with vitality, joy and optimism. It is believed that this stone inspires positive thinking, helps to overcome insecurity, reveal leadership qualities and attract good luck. Its warm energy promotes enthusiasm, creativity and a sense of inner light.

Oligoclase, especially in the form of Sunstone, is a valuable collector's mineral and a popular material for creating original jewelry that radiates warmth and light.
