Black opals are among the rarest and most prized varieties of opals, revered for their deep, dark base color that provides a dramatic contrast to the vibrant flashes of spectral hues. These opals owe their unique coloration to the presence of carbon and iron oxide in the silica gel from which they form. Unlike common opals, which are typically opaque and lack play of color, black opals possess a distinctive opalescence that mesmerizes beholders
