This is a very beautiful loose natural Australian boulder opal from the Queensland opal fields. This gem opal displays a rich tapestry of colour in the full sprectrum with big bold broad flashes illuminating throughout the stone. The size is excellent and would be ideal for a stunning diamond halo ring as the centre stone, or similar in a pendant. It has a nice high dome and the crystal like clarity of this opal lets you view inside the stone and see the full display of the colours dancing within. An excellent boulder opal and a very good choice for wear or investment.
