These multicoloured natural mined Australian rough opal rough and rubbed stones were mined at around 45 feet on the 16 Mile Creek (shallow 17 Mile) opal field of Coober Pedy Australia.


After 30 years in the opal business, we firmly believe opal can be the most beautiful gem on Earth, and we love the colourful characters and lifestyle of the outback opal fields. Here at World Class Opal we are privileged to do our best to acquaint the world with the colour, light and beauty that quality Australian opal jewellery has to offer.




Item Specifics:

WEIGHT: 17.5 carats,  7 stones.

These are medium yield pieces that should cut around 4-6 carats of lovely solids, doublets, inlay or intarsia etc. (higher yield would likely be achieved if carved.)

Use the ruler as your guide to size (IN INCHES)

We do not sell opal simulants of ANY sort. All of our opal is 100% guaranteed Natural Australian Opal.

The color variations in some photos are due to different light angles and distances. All of our auctions are photographed with macro settings under a 60 watt incandescent lamp. In all photo's the opal is immersed in water.

Please check the dimensions carefully as the opal will not be as big in your hand as it looks on your monitor! Also some monitor settings will cause white based opal to look darker than it actually is. Please check the description carefully before bidding and view your purchased rough opal wet in sunlight or in a dark room with a direct light source ie: desk lamp, down light etc. (As photographed and practiced throughout the opal industry).
