Sunstone ring

95.00

Materials: sunstone, sterling silver

I used a hammer texture on three rings, soldered them together and bezel set the sunstone.  The dark effect is caused by an oxidyzing patina to enhance the texture exhibited.  

If it isn't currently the correct size for your finger, just let me know what it needs to be and I can change it in a jiffy.  

Sunstone is a plagioclase feldspar, which when viewed from certain directions exhibits a spangled appearance. It has been found in Southern NorwaySweden and in various United States localities.

The optical effect appears to be due to reflections from inclusions of red copper, in the form of minute scales, which are hexagonalrhombic, or irregular in shape, and are disposed parallel to the principal cleavage-plane. These inclusions give the stone an appearance something like that of aventurine, hence sunstone is known also as "aventurine-feldspar." The optical effect called shiller and the color in Oregon Sunstone is due to copper. The middle part of this crystal sparkles, and usually the color is darkest in the middle and becomes lighter toward the outer edges.

The feldspar which usually displays the aventurine appearance is oligoclase, though the effect is sometimes seen in orthoclase: hence two kinds of sunstone are distinguished as "oligoclase sunstone" and "orthoclase sunstone."
