I have been brought up around opals all my life and I have always been fascinated by this beautiful stone. In 2011, I decided to follow my passion and start in the the gemstone industry after serving 7 years as an electrical engineer. Chroma Gems offers opals from all over the world, but mainly from the Australian sites of Lightning Ridge, Coober Pedy, Koroit and Yowah. All of the stones are direct from the mines and have not been treated of modified in anyway unless clearly indicated. That is something Chroma Gems prides itself on. We offer a 100% money back guarantee on all purchases. Australia post is the main postal service used as it has a excellent reputation for delivery to most parts of the world. We hope you enjoy what we have to offer and we hope you find a piece of treasure of your own.
