Explanation: 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. Rough opal is not easy to identify at times and if you find that anything you order does not come up to a finished value that you can at least double your money on your investment, please let us know and we will give you extra bonuses in the future. And dont worry, we trust your honesty in this matter.

Recommendations: Traditionally, opal has been cut in the oval shape. In recent times however, because of the scarcity of the stone, the practice has been more to cut opals in their free form shape. In other words, whatever shape they naturally come in, or to a shape that you would like to create yourself. By doing this, you are creating a gemstone with much more design potential because you will have both the natural uniqueness of this amazing gem and a shape different to others. This inspires creativity in design because free forms have much more design potential. Please take a look here for some good ideas.

  1. Pepe

    Can this be customized by this company to fit into a ring like the one shown

    • admin

      Pepe, yes it could be but there would be a lot of waste. I would assess that the rectangular stone in your ring is about 6×4 mm.(approx 9/32 x 5/32″) maybe 7×5 mm (please measure it and let me know) 8301 is 14×5 mm This stone is unfinished. If you are a stone cutter of course you can cut and polish it the way you want. If not it will cost $50 to cut into shape with a lot of waste. It would be better to get a stone with less waste. i will email you. peter
