‘mine run’ Explanation: The term means that the stone is pretty much as it comes out of the ground. Some cutters prefer the excitement of searching for the color rather than to have it exposed. We must warn you that buying opal this way can be risky from a value point of view because you cannot be sure what you will find. Maybe some exciting surprises and sometimes disappointments, but as stated below, we always take a keen interest in the results of any rough supplied, and are happy to help you with more material if the results are disappointing.

Rubs: The term ‘rubs’ refers to the practice in Australia of cleaning away most of the unusable opal potch and other impurities so that you are not paying freight for material that is just waste. If you need some cheaper opal for practice, please make a request for this in your order and we will include some as a bonus. Sometimes some nice gems are found in this material, and we are happy if you benefit by this.

And dont worry, we trust your honesty in this matter.
