This pendant is set with an excellent Australian opal from Coober Pedy, which has a cream-coloured background with fire of at least 4 colours: red, orange green and blue. The stone is drop shaped and is 1.8cm long and 1.2cm wide, which is a fair size for such a good stone. I set it in a Sterling silver surround with a 9 CT gold hanger, so that it can be worn with either a silver or a gold chain. Both metals are hallmarked for Edinburgh 2016. The entire pendant is 3.3cm long and weighs 3.55 grams. It comes with an 18″ Sterling silver snake chain and will be sent gift boxed.
