Yes, hydrophane opal have a surprisingly perfect diffraction pattern, being able to refract multiple images of the light source back at you in different colors. I have also discovered, with some naturally crystal clear opal, after submerging in water and drying, the body color turns white. But after a few months or so, the body color reverts back to crystal.
@@gemstory i have ton of this opal and i manufacturing this opal, more then 100 kg stones have polished one. fire back after heating with sunlight .. like 20 min or half hour full fire back and original condition .
Dont worry about that ..boilt point and water states such as liquid,ice,gas will answer that ..remind me again about the Australian opal cant absorb water please..i live on high altitude with out A/C.. absorb vs resist ..we will see
@@birruahimed7253Australian opal is sedimentary Ethiopian and most other opal is ignious, sedimentary opal has very tightly packed layers of silica spheres hydrophane opal is much more irregular and absorbs liquids. Almost all Australian opal does not crack over time yellow or absorb liquids while Ethiopian opal of all the hydrophane opals has the highest chance to crack yellow and absorb liquid.
I have a Ethiopian Opal which changes colour rapidly. When it comes into contact with water it becomes translucent, & after some time it turns white. It also emits blue rays at times. I want to know, is it Opal or some other ordinary gem stone ?
Your opal sounds very "Hydrophane Opal", maybe it has some nice blue flashes ... just too hard to say much without seeing the picture of your opal Arun.
एक बार ओपल को पानी में थोड़ी देर तक रखने से कुछ नहीं होगा बल्कि ओपल को नहाते समय या पानी में काम करते समय पहने हुए रहने से कुछ दिनों बाद फायर चली जाती हैं
Hola, yo tengo un ópalo etíope y cuando lo compré era blanco, luego lo usé lo puse dentro de la caja y cuando lo fuí a usar, estaba transparente, qué hago?
This is what happens with clear water... what do you think putting black carbon goop into the spaces between the spheres?... there are no colors in the stone, the structure of the stone breaks light into its component colors... by the orderly arrangement of spheres and spaces... to do this, each sphere must be half the size of a wavelength of visible light... the phenomenon is governed by Braggs law of diffraction... if you fill the spaces between the spheres... no more colors
@@bellashegitu747 i can advice Roy rocks and black opal direct channel on youtube. They have alot off good video's. Learned alot there. You can try a zip bag to slow down the drying proces.
My opal ring turned a clear yellow and Hasn't returned to it's original shimmer😞 I've left it in the sun for several days.. Is there anything else I can do??? It was a gift from my mom before her passing..
Hey, thanks for making this video. I put my eth opal into hot water with some ring cleaning normal chemicals. After cleaning i saw it turned into light brown clor and one side was cloudy like half boiled egg and the fire on that side was almost gone or got dull. Kindly tell me will it come back to normal or not?
Thanks for your comment. When it changes the body tone and colors due to the chemical, there's less chance to get its original beauty back .. please try to soak an opal into some pure water for few days and see if the color comes back.
@@gemstory Thanks for replying but Im not sure what you mean. It might not come back you think? It is real raw ethiopian opal pieces....im trying drying it out in uncooked rice I know the rice absorbs water. My color came out from humidity in my house from the weather outside I assume. I live in NY. Im so upset about it it happened to a few of my favorite pieces. I will try sunning them if rice doesn't work. They are completely transparent with a tiny flash of color.
Jennifer, i am sorry to hear all that but some ethiopian opal will lose the color forever and some will get the color back it all depends on the quality and its origin ... We are not a specialist for ethiopian opal so it might be best to check this page out and understand the characteristic of ethiopian opal. geology.com/gemstones/opal/ethiopian-opal.shtml Hope the link will help a little. Thanks for your time and understanding. Kindly, Malayvone Souvannavong
this was happening to me on my wedding ring it was the saddest thing ever what we did is we replaced our Ethiopian opal stone with an Australian opal stone and the color is steady as a rock ! hope this helps !
Great to hear that. If the color of opal went clear / translucent by the clean water, some gets the color back. If not a clean water, usually the opal loses its original beauty.
@@gemstory now that is the problem, i did a test using clean and clear water, but if the water is cloudy or mixed with other compounds then i agree the color most likely won't come back as before Thank you for reminding me this point
@@alaiaadam5767 Water opal can be "man-made" or can be not, it all depends on where an opal is from. Please do some researches on "Mexican opal" or "Water opal" through internet, you'll be surprised how much information you can find about "water opal".
This experiment is only to show the difference between Australian opal and Ethiopian opal .. Don't do it to Ethiopian opal but Australian opal is OK !! It won't lose its color. ^^
We are not trying to make a bad image on an Ethiopian opal but trying to show how some hydrophane opal absorbs the water and change the colour. Thanks for watching our video.
I noticed a crack in one of mine after doing this and the opal return to full opage white. Not like it was before. I just did it to clean off the clay and show the stone. Crazy experiment. Thank though now I know why. They are still beautiful. I noticed iced if I keep it cold the stone will stay more clear. If it is hotter or being polished it generates so much heat it happens in second before my eyes. Gotta show a video
Not all opal will change or lose the color like this and that's why we believe Australian opal is more stable and precious. Please try and understand our point of view by learning from here, thanks for your comment (^^)
