Moonstone is a variety of feldspar, in the same class of minerals as labradorite and sunstone. Moonstone can be many colors, but it is commonly a pale blue with shiller (shiller is like sparkles as it is relfected in the light). This moonstone is collected from Sinkhole Mine, North Carolina. In this area, large magma bodies intruded into the surrounding rock during the formation of the Appalachian Mountains. Throughout the region, these magma bodies produce many gemstones including emerald and aquamarine, as well as economic minerals such as muscovite.

At this location, the magma intruded into rocks that were rich in calcium and sodium, rocks that were originally limestone from the ocean floor. When the magma intruded, some of the elements from the magma seeped into the surrounding rock and produced some unusual minerals with calcium and silica. Likewise, some of the elements from the limestone seeped into the magma. The moonstone is a result of this interaction with the limestone.

Please enlarge and view the photographs for more detailed views. Shown wet to simulate polish. As with all natural rock, there may be fractures or pits to seal or work around. Each slab has the approximate dimensions listed. I use the longest and widest point and the thinnest, it’s not averaged.

We have worked hard with the lighting and the settings on the camera so that the colors are very accurate. Individual settings may affect color viewing on various devices and I cannot predict what your device will do, but on my computer, they’re dead on for color. I appreciate your business!
