This pendant is set with an Australian opal from the Coober Pedy mines. The stone is drop-shaped and is 1.5 cm long and 1cm wide at its widest point. It displays lovely light blue and green fire on a cream-coloured background. I have set it in Sterling silver, adding a kind of halo, to accentuate the shape of the stone, but leaving the stone itself free to sparkle on its own. The entire pendant is 3.7cm long and 2.6cm wide. The back is hallmarked for Edinburgh 2017. It comes with an 18″ (45cm) Sterling silver snake chain and will be sent gift-boxed.
