Rainbow Calsilica, also known simply as Calsilica, is a striking opaque material celebrated for its vibrant, multi-layered bands of color, which can include hues of blue, green, yellow, orange, red, black, and sometimes even pink or purple. While initially presented as a natural stone mined in Chihuahua, Mexico, extensive testing has revealed it to be a man-made composite. It consists primarily of powdered carbonate rock (calcite), silica, artificial coloring pigments, and a plastic-like stabilizing agent, often resembling paraffin wax. Despite its artificial origin, Rainbow Calsilica is highly sought after for its bold appearance and is commonly cut into cabochons, beads, and carvings for jewelry and decorative purposes. Its unique visual appeal makes it a popular choice for designers seeking a colorful and distinctive material.
