Meeting all the miners that Bill buys from in Australia has been a special treat for me in the last two years.  Alice & Avon recently closed the mine that this opal is from.  I've purchased many stones from Bill from this mine and admit that I have hoarded them.  I'll share this one :)  So unusual in nature, half green, half red.  A chrome type sheen in the Yowah Opal.  I drilled and set a sunset topaz within her, dangled her off a black diamond 18k gold chain.  She is ready.
