It is a semi-precious stone and quite rare. This stone is not readily available just anywhere. However, it is popular in rosary and jewelry. You will see various blue patches on its surface, which gave it the name blue spot jasper. The stone also comes with some near-earth and brown color spots, making it look like it is straight from the ground below.
Blue spot jasper has a smooth surface and extraordinary characteristics, just like other natural gemstones. Even though blue spot jasper is not transparent, it bears a bright color. Many people can easily confuse this gemstone with a lapis lazuli or sodalite.
