A 0.20 carat oval Ethiopian opal with 0.29 carats of oval fire opal in 18K yellow gold over sterling silver band ring measuring approximately 0.77 inches long by 0.12 inches wide - the two-opal band ring where Ethiopian opal's crystal play-of-color and fire opal's vivid orange-red appear together in warm gold. Ethiopian white opal shifts through spectral colors; fire opal's vivid orange is its own self-contained color statement. Two opal varieties with distinctly different optical characters. Not sizeable.
