The Sonora Sunset is a fascinating gemstone composed of three main minerals: chrysocolla, cuprite, and iron. This semi-precious stone displays a vibrant range of colors, from the intense blue-green of chrysocolla to the vibrant red of cuprite, with black hues of iron in between. Together, these elements create a strikingly beautiful cabochon, often called Crimson Cuprite due to the predominance of red cuprite.
