Our Opal: An Ethical Choice

At Broken River Mining we are committed to being both environmentally and socially responsible.

Sue and her small team use environmentally responsible procedures in mining and processing all BRM opals. We mine small sections of land at a time and we always rejuvenate the land when we are done.

All opals are mined by us in Queensland, Australia.

Shipping updates

At Broken River Mining we want to provide you with the best customer service we can. Currently, due to international restrictions, delays of 2 - 4 weeks can be expected for all international orders via Australia Post. Express items will still be given priority during this time, but unfortunately not at their normal speed. All our orders have an Australia Post tracking number and this tracking number can also be used with your country’s local postal network. For example, our United States customers can use their Australia Post tracking number on the United States Postal Service (USPS) tracking website too. Please feel free to contact us if you have any questions and thank you for your patience and support.
