I just love this piece, it is like looking into an underwater cave. A 3D effect with the see through opal, just lovely. It was a twig of wood which has turned into opal imbedded in the ironstone The stone measures approx 21.5mm. Measurement of pendant including the setting (but not the bail) is approx 28.5mm x 7mm. Narrowest mesurement inside bail is 4mm
