Dichroic red and green Oregon Sunstone. This matched pair of earrings has the fascinating ability to show two different colors at the same time. These types of gems are rare to come by as the gemstone must be cut in just the right axis to keep the red and green colors from mixing within the stone. These gems are 2.7 cts ea., 7mm and show predominantly the green color. Set on a sterling silver post with friction backing.
