We make it a priority to use Australian stones where possible and have great relationships with our local suppliers. When local sourcing isn’t feasible, we partner with trusted gem merchants with whom Millie has built committed relationships with over the last 10 years. All opals come directly from miners in Mintabie, South Australia and majority of our GIA diamonds come from suppliers in Melbourne.  

Furthermore, we recycle all our metals on-site, maintaining an eco-conscious approach in everything we do, and we are always striving to improve where we can.
