This is a plain silver pendant which is set with a good, drop-shaped black opal from Lightning Ridge in New South Wales. The opal has a deep blue background with strong flashes of lighter blue, which appear turquoise according to the angle of the light. The stone is 1.6cm long and 8mm wide at its widest point. The entire pendant is 2.8cm long. The back is hallmarked for Edinburgh 2018. It is a relatively small pendant which is very dressy in its simple elegance.
