The scientific name of the sun stone is heliolite, heliolite or Venus feldspar, which belongs to a kind of plagioclase and is mainly distributed in western Norway and some parts of the United States. The surface of the sun stone is glassy and has a certain bicolor. It can show different colors under the light of different polarization directions, that is, the daylight effect.
The scientific name of the sun stone is heliolite, heliolite or Venus feldspar, which belongs to a kind of plagioclase, because the crystal feldspar contains hematite, goethite and many other neatly arranged, reddish-brown flaky mineral inclusions with bright colors. When irradiated by light, it can reflect glittering bright spots, which is named after the radiance of the sun.
Solar stones are heterogeneous, with a glassy surface and a hardness of about 6-7 degrees Mohs. The inclusions inside are often in parallel plate-like shapes, and the aggregates are in blocks and other forms. Due to the dual-color nature of solar stones, they can show different colors under the illumination of light in different polarization directions, that is, the daylight effect.
Sunstones are mainly distributed in western Norway and some parts of the United States. They are state stones in Oregon, the United States. When sunlight shines on the sunstones, it can be seen in a translucent state. The color is often dark orange, gold, and golden brown. Occasionally, colorless and transparent.
