UPDATE: Price dropped by $640, now it is a super bargain!

There are six types of schiller (copper inclusions) occurring in Oregon sunstone. This deep red Oregon sunstone has speckles of copper looking like champagne bubbles, especially visible from the side (see photos). Schiller that doesn’t overwhelm the color or clarity of the sunstone, as in this case, combined with the interest it adds, increases the value. Collectors look for this very feature and with color like this, off the charts vivid deep red, it is a true collector’s gem. However, it sure would look great in jewelry too! Precision faceted by Loren Brown in a beautiful design by Robert Long.
