Given the age of our earth, and that the oldest minerals have been around for literally billions of years, it is surprising that geologists are still making new discoveries. However, such is the case with tanzanite. It was discovered in Tanzania only a few short decades ago; in fact, that area is, so far, the only known source in the world. With its rich, velvety blue hue, tanzanite is fast becoming one of the world's most desired gemstones. Now you, too, can experience the joy of owning one of these exquisite gems. This lovely sterling silver ring is sure to add that extra touch of elegance.
