Description

SEDA OPALS
This is a natural piece of shell opal fossil. 100 million years ago inland Australia was a vast sea. The shell voids were replaced over time by opal making a unusual rough.You will find the stone slightly curved as it follows the shape of the shell so care should be taken when setting.It can also be made in to doublets.
Mined in Coober Pedy Sth Australia.
photo taken wet

I suggest you look at the rough dry and wet before cutting as we only refund on untouched rough.

    This is my 2nd opal from Sedaopals. The last one did not disappoint. I am super excited about this one. If this continues, I will buy again.

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.
