Description
This opalised Cretaceous fossil was mined by us on the opal fields 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 has to offer.

Item Specifics:
VIDEO: https://youtu.be/DliQkDHRBQo
WEIGHT: 43.5 carats, weighed dry.
DIMENSIONS: Approx: 36 mm by 16 mm by 8 mm.
The best colour has been polished on this piece leaving as much fossil definition as possible.
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 halogen lamp. In some 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! 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).

Why are users outbidding themselves?
Automatic Bid icon
Automatic Bid
When a bid is placed, this is the maximum amount a person is willing to bid for the product. Our system will then automatically bid on behalf of the bidder, incrementally increasing the bid up to the maximum to maintain their position as the highest bidder.
When there is an icon indicating 'Automatic Bid', it means our system is actively placing bids for the bidder based on their maximum bid. This may appear as if bidders are outbidding themselves, but it's simply a result of the system updating the bid to reflect the bidders maximum limit.
Audit
The Opal Sheriff program allows our members to request an audit on any product, which is completed by an independent Gemologist who assesses the accuracy of the item description and pictures.
