FAIRY OPAL ROUGH 
NATURAL UNTOUCHED UNTREATED
NOW YOU CAN HAVE SOME FUN DISCOVERING THE COLOURS.

This is natural untouched fairy opal . This rough has been oxided  by time as the out side will be darker then insided but it should treat well and be high yeilding with stones once treated. They are ready to be shaped or cut into smaller stones or for earrings ect. We bought a few 44 gallon drums and only selected the pieces showing some colour. There is a large amount of wastage. 
It is precious opal embedded in the natural sandstone and mined in Queensland Australia.Only by carbonizing it does it become like black opal..The treatment  are listed below
TREATMENTS
--On the opal field the normal treatment is to wrap the stones in aluminum foil with a some sugar and olive oil and throw into the hot coals for 15 minutes in a out side fire.I have tried this with varying success.
-This treatment you could also try with some oil.
You can heat the stones in a oven to 90 degress F  for a hour to dry them out
Place gently in a bowl with syrup of sugar. Heat for 8 plus  hours but not to boiling as you will loose the water so the sugar seeps in to the stone-i once left for over a week and had good results.
Wrap in aluminum foil and heat to 400 F for 4 hours-you can check earlier. This is best done on a out door bbq,kiln or oven.
-You can treated like Andamooka matrix with acid-details are in the learning section on the site.

TREATMENT FOR FAIRY OPAL AND ANDAMOOKA MATRIX WITH SUGAR ONLY.


MATERIALS
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.
Remember to have fun!

POLISHING
This parcel The surface is porous so its hard to get a good finish.
You can polish as a natural stone or coat it with resin to get a better finish.
We suggest a polymer resin as its stable.inert and nontoxic and dosent yellow..Check out our listings of fairy opal polished in sedaopals.Some of there were polished in china under vacume with a amazing finish.
We have also used mono-compontent thermo set resin,cynoacrylates and 2 parts resin but these can turn yellow over time. ive even heard of nail polished used and hardened under uv lights.

The weight and size is app
It is similar in appearance to Honduran opal.

seda rough opals
seda rough opals
SEDA ROUGH OPALS is run by Paul Sedawie of Seda Opals. 8 opals can be combined in the one shipping if bought with in 7 days. The Seda Opal company was incorporated in 1994.The owner Paul sedawie is the current president of the OPAL ASSOCIATION INC. Seda Opals is an abbreviation from our surname Sedawie. The business is mainly wholesale and it is through this site that we can bring the opal fields and the bargins direct to you. Paul Sedawie started mining at the Four mile field in Lightning Ridge in 1986 with his first partner Bob Young. It took them 6 months to find a decent stone and this experience gave me a healthy respect for the stone and how hard it is to find. Previous to mining opal, Paul ran a successful mail order business in plants for 7 years which gave him a lot of experience servicing customers through parcel post. We use mainly Australia post as it has a excellent reputation for delivery to most parts of the world. I don't do any active mining now but my eldest son Peter Sedawie has taken over. This leaves me free to travel to any opal field and to enjoy the beauty of this magnificent stone. We hope you enjoy our stock and good luck with your biding.

Zašto korisnici nadmašuju same sebe?

Kada se postavi ponuda, to je maksimalni iznos koji je korisnik spreman ponuditi za proizvod. Naš sustav će zatim automatski licitirati u ime tog korisnika, postupno povećavajući licitaciju kako bi zadržao svoju poziciju ponuditelja najviše, do navedenog maksimuma.

Kada postoji ikona koja označava "Automatsku ponudu", to znači da naš sustav aktivno daje ponude za korisnika na temelju njihove maksimalne ponude. Ovo se može činiti kao da korisnici sami sebe nadmašuju, ali to je jednostavno rezultat ažuriranja ponude sustava kako bi odražavala maksimalno ograničenje korisnika.

Revizija

Program Opal Sheriff omogućuje našim članovima da zatraže reviziju bilo kojeg proizvoda, koju dovršava neovisna :kvalifikacija koja procjenjuje točnost opisa artikla i slika.
