Description

ANDAMOOKA HARD MATRIX

This material came from a retired miner who said he found it in the 1980s. Inside the old box was a paper from the 1980s and interesting enough he said he even made triplets from it!

This material will take a natural poliosh so no resin needed.All rough can be a gamble but exciting also.

You can dremel and keeps its natural shape or if you cut deeper you will have to re treat.

I treated some with oil which did make it darker but not a great result.

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.
