We sourced this boulder opal from Yowah, QLD. The opal's fire like orange and intense blues evoke the feeling of a vivid sunset. The opal measures 22mm wide x 9mm deep x 9mm wide. The stone is quite deep giving the impression of an optical illusion when moved. The strong colours really move around in this stone due to its depth. There are so many interesting inclusions and minerals inside the opal. One of the first comments we got was that it looked like there is an underwater mountain range inside the opal. If you choose this wonderful stone, I'm sure other visual references will present themselves. Cut, polished and set by hand in Melbourne, One Of A Kind piece. Presented on a 45cm Italian sterling silver chain.
