all info pertaining to australian opals and opal fields is ok. online valuations is difficult but not entirely impossible. Photographs of stones should clearly show weight in carats and scale in mm. naturally photographs of opals are the hardest thing to take as a slight shift in direction displays a new colour or plane

Experience in the area

Born into a pioneering opal family , now 48 yrs old , visited every opal field in australia, seen some of the finest stones ever produced . Sold high quality gems to japanese collectors and europeans and Americans
Have an incredible photogallery of opals ...try me !

What do you like about this subject?

That you can not just learn this information from a book without a lifetime of handed down experience.

What do you still hope to achieve/learn in this field?

That beauty in the natural world of gemstones has no price .

Something interesting about this subject that others may not know:

Gem Opal is much more rare than average Diamond. Gem opal are becoming more difficult to find as the easy ground has all been worked in Australia . Only some extraordinary events will see exploration into fringe areas in Australia. Its almost like Mars ! There just might be an asteriod or planet that has properties similar to the Opal ...wouldnt that be wild !

Something controversial or provocative about this subject

There is no more opal being made by mother earth . 96% of the worlds gem opal comes from Australia. There is no known way of detecting precious opal . Once upon a time it was sought after from all corners of the world, now everybody almost has everything . Not everyone loves opal but those that do still have the ability to dream in colour beyond the square !
