An 11x9mm oval orange sunstone with 0.18 carats of pear white Ethiopian opal and 0.11 carats of round white zircon in 18K yellow gold over sterling silver ring - the ring where sunstone's distinctive warm orange adularescence and Ethiopian opal's play-of-color create two optical phenomena in a single piece. Sunstone exhibits adularescence - a floating copper-to-orange glow beneath the stone surface; Ethiopian opal produces spectral play-of-color. Two exceptional optical phenomena in warm gold. Not sizeable.
