The opals are found in rhyolite geodes (thundereggs) in a perlite that has altered to a pastel colored clay. The geodes that contain gem-quality opal are only about 10% of the total geodes mined and only about 1% of the geodes contain gem-quality opal with play of color. The remaining geodes contain agate, quartz crystals, or common opal. The geodes vary greatly in size, from a few centimeters in diameter to over a meter.

Great! What more can I say. The service, communication, speed of shipping and packing of my order was perfect. Very happy. This stone goes from looking like a drop of water to a beautiful play of colour.
Great! What more can I say. The service, communication, speed of shipping and packing of my order was perfect. Very happy. Very tempted to make a piece of jewellery out of this as the orientation of cutting suits it.
