Opal cutting is never a sure thing, and working with Allawah Nobby Opal, the stakes feel even higher. The Allawah field in Lightning Ridge is one of the newest opal-producing areas, known for its exceptional crystal opals with vivid play-of-color. In this latest cutting adventure, we take on a beautiful 10.30-carat clean skin nobby, full of promise but also uncertainty. With inclusions and sand spots lurking beneath the surface, the challenge is clear: can we reveal a truly spectacular gem?

Cutting an Allawah Nobby Opal
From the start, this opal showed signs of both potential and peril. The outer skin was thin, hinting at vibrant color within, but sand inclusions threatened to compromise the final gemstone. With a cautious approach, the first step was to remove just enough material to assess what lay beneath. The weight of the piece, coupled with a $2,000 investment, meant that every decision had to be precise—one wrong move could mean losing thousands in value.
Initially, the plan was to grind away the back to access cleaner color, but instinct suggested a different approach. Instead of removing too much too soon, a careful surface cut preserved the brightest play-of-color. A strategic slice then split the opal into two, maximizing yield and giving us a chance at not one but two beautiful stones.
A Stunning Outcome and a Future for Opal Mining
In the end, the risk paid off. The final result: a breathtaking 2.87-carat Allawah Nobby Opal, valued at $4,000, plus a bonus smaller gem. This journey serves as a reminder of the delicate balance between skill, patience, and luck in opal cutting.
While the Allawah field continues to produce some of the finest crystal opals, the bigger question remains—what does the future hold for opal mining? With fewer young miners entering the trade, the availability of these extraordinary gems could become scarce in the years to come. But for now, each discovery keeps the magic alive, ensuring that opal enthusiasts worldwide can still experience the thrill of a truly special find.

Well done, Justin. Just wondering why you didn’t put a higher dome on it? Is it to keep the weight higher? Does it make a difference in the quality? Does it magnify more? You are the best. I am learning so much….and I have been cutting for over 30 years. Some day I want to come and visit. I live in Utah. Might be a while!
Yes a high dome has the ability to create 3d color on color which can be very nice. I love a dome as it set the scene for a perfect cut
