ANDAMOOKA ROUGH TREATED
We bought this from a miner who roughly treated it and only cut the gem pieces.They have only been roughly treated so they may improve but its still a gamble but at least you know there will be colour.

This is a natural opal treated so it becomes black. You can cut as stones or leave as specimen or for carvings.  but you will have to re treat if you take too much away.
You may see black spots which is usually blackened sugar which will come off. The miner has just roughly treated and rubed them down.
Mined in Andamooka Sth Australia
We have taken the photo of the rough wet! We have cut stones from this parcel which are listed in sedaopals.
All rough does have a element of a gamble as some may treat better than others but this has been treated to show what the colour will be like.
TREATMENT FOR ANDAMOOKA MATRIX WITH SUGAR ONLY.
MATERIALS-BUT YOU CAN TRY OIL IF YOU LIKE
250 grams glucose,white castor sugar,pot or pressure cooker,plastic tweezers.
STEPS
-Pre shape the material


- Thoroughly dry the material in oven sun or hairdryer. You can also soak in aceton for 10 minutes to dry the stones out.
- Put water in pot on low temperature and add glucose and castor sugar. DO NOT BOIL.
-Place warmed stones into warm solution and cover the stone with liquid.
-leave on low temperature for 24 hours but DONT BOIL.
-Remove with tweezers and let cool.Use a paper town to wipe away access.
The next steep is to carbonize the sugar in the stone. Place the stones on a metal or pyrex dish and place in a kiln at 500 F degrees for one hour.This will burn or carbonize the sugar in the stone.
_When the stones have cooled clean on a grinding wheel.
Remember to take all precautions with gloves and mask and clothing with good ventilation.
This is a natural product so results may vary a bit due to how porous the sandstone is. Some material will have to be treated a few times to get good results. You can also experiment with various temperatures as i like to cook with lower temperatures.
You may have to treat a stone a few times to get the desired result.
Remember to have fun!
WE HAVE TAKEN THE PHOTO WITH THE ROUGH WET.
In the learning section of opal actions there is details on how to treat with ACID and sugar but this sugar only gets good results if the material is porous

Why are users outbidding themselves?

When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.

When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users 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.
