This set of agates is Picacho agate from Mexico. Each half measures approximately 2.5 x 1.5 x .5 inches and is face polished. The pair weighs 3.9 ounces and comes in a plastic floating frame that can be displayed on a flat surface. Any fractures are a natural part of the stone. This is a single agate cut in half. The variance in the sides is a result of the amount of material that is removed by the saw blade when cutting.
