New to Buying Australian Opal Online?

Buying opal online requires understanding what makes Australian opal valuable and how to verify authenticity. Body color determines base value—black opal commands highest prices, crystal opal shows brilliant color when quality is high.

Origin verification is critical. Lightning Ridge produces genuine black opal. Queensland fields produce boulder opal with natural ironstone backing. Always verify specific mine location, not just Australia.

Pattern type affects value exponentially. Harlequin is rarest and most valuable. Chinese writing commands premium pricing. Red color dominance is most valuable, followed by orange, yellow, green, blue.

Video documentation is non negotiable. Photos can be manipulated. Professional sellers provide unedited video showing stone rotation under standardized LED lighting.
