The name "sunstone" is used for specimens of translucent to transparent feldspar that produce bright metallic flashes when light interacts with tiny plate-like mineral inclusions within the stone. These mineral inclusions usually have a common orientation, and light entering the stone reflects from them at a common angle. This produces a flash of light in the eye of the observer who views them at the proper angle. This optical phenomenon is known as "aventurescence."

The first materials to be called "sunstone" because of their aventurescence were specimens of oligoclase, a plagioclase feldspar. As other types of feldspar with a strong aventurescence were discovered, the name was also applied to them. Labradorite feldspar (another plagioclase) and orthoclase feldspar have both been found with strong aventurescence. 

The aventurescent flash of light produced by a sunstone can be observed by three different actions:

  1. moving the stone in the light
  2. moving the position of the light
  3. moving the eye of the observer

Sunstone is also known as "heliolite" and more commonly "aventurescent feldspar." It is cut into cabochons, beads, and small sculptures. The most transparent pieces are used to produce faceted stones.

Sunstone is popular with innovative jewelry designers and is especially popular in the geographic areas where it is commercially mined. It is not a gemstone that is seen in every jewelry store, and many jewelry buyers have never witnessed its aventurescence. However, once a person is given a demonstration of sunstone’s aventurescence, they often want to try it and are fascinated. It is a gemstone that sells best if the jeweler takes a moment to educate the buyer about aventurescence.

Sunstone Localities

Aventurescent feldspar has been found in Australia, Canada, China, Congo, India, Mexico, Norway, Russia, Sri Lanka, Tanzania, the United States (Oregon, New York, Virginia, Pennsylvania) and other localities.

The most famous sunstone deposits in the United States are located in Oregon. A few of the sunstone deposits in Oregon are large enough to sustain mining operations. They are found in certain basalt flows in Lake County and Harney County. There the sunstone occurs as phenocrysts within the basalt. Some sunstone is produced from the weathered zone above the basalt flows, and some is produced from the basalt.

The Oregon basalt flows that contain sunstone are located mainly on public land, and many productive or promising areas are held by mining claims. The U.S. Bureau of Land Management has reserved one area in Lake County as a public collecting area where anyone can enter, look for sunstone, and keep what they find for personal use. Collectors must follow BLM’s collecting rules and stay off of adjacent lands where mining claims have been registered. Collecting on land with an active mining claim can only be done with the owner's permission.

Inclusions that Enhance Desirability?

Inclusions are particles of foreign material in a gemstone. They cause a reduction in the clarity of the stone and usually decrease its desirability. However, some inclusions in sunstone can enhance its desirability. These inclusions are perfectly flat, highly reflective and precisely aligned to simultaneously produce a flash of light. Instead of detracting from the stone's beauty, these flashes of light usually delight the observer and increase the desirability of the stone.

The inclusions in sunstone are usually tiny plates of copper, hematite, or goethite aligned parallel to crystallographic planes within the stone. 

Stones with a small number of inclusions produce a weak aventurescent flash. Those with a greater number produce a stronger flash. Stones with a strong display of this optical phenomenon surprise people and are highly desirable.

The inclusions in sunstone can be so small that they are not visible to the unaided eye, or they can be large enough to be clearly visible. The inclusions are extremely thin. Even though they might be large enough to be clearly seen face-on, they are usually too thin to be visible when viewed from the side.
