An Australian Black Opal with fiery flashes set in our signature 14k floating setting. Ring is a size 7.75. Inquire for re-size. See photo on hand for scale. *Opals are extremely soft and porous stones, which means that they absorb moisture. Be careful not to wear opals in any water, during exercise or excessive sweat, or in extremely humid climates as these conditions can result in your stone discoloring, or cracking.*
