Oregon sunstone is mined in two broad areas of the state more than 100 miles apart: the Ponderosa mine in Harney County, in central-eastern Oregon, and the Plush mining area in Lake County, southwest of the Ponderosa.
Sunstone is a stone of personal power, freedom, and expanded consciousness. Of all the stones on Earth, this one truly reflects the qualities of Solar Light - openness, benevolence, warmth, strength, mental clarity, and the willingness and ability to bestow blessings on others. The "Schiller" phenomenon makes the stone appear to "glow" as if it had it's own internal light source. Sunstones can kindle the fire of leadership within those who wear or carry it.
Extensive study of the Ponderosa mine sunstone labradorite has revealed a number of distinctive characteristics, including aventurescence and pleochroism, as well as provided information to help determine the cause of the different colors. This sunstone can be readily identified on the basis of its gemological properties.
