Hi, thank you for the video, do you know if a clarity enhanced opal by being heat treated changes the value of a stone and by what estimation?
Omg guys thank you for this I have been looking for this info for a while
Nice video, but I think the maths is wrong… she is dividing the weight of the stone in air by the weight of the stone in water alone, NOT by the weight of the stone in air MINUS the weight of the stone in water (as is shown in her example equation). In the case of the dyed Ethiopian stone, the equation should read: 19.45 carats/(19.45 carats – 11 carats) = a specific gravity of 2.3, not 1.7. But the video is very helpful — thanks for posting!
I have sone question sir if its okay with you
This is very useful thanks
Seems like a Propaganda for Australian Opal. Please see your calculation, The specific gravity of Ethiopian Opal is 2.3 based on your own formula.
Whatspp do
You forgot the triplet opal..
Very much thank you for this video! I know it has been really requested on the opal reddit community.
Your website and your opal info is by far the best to be found, thank you. So much BS out there
Did you forget your own mathematical formula? Cos 5.8 /(5.8-2.9) = 2.0 and 19.45/(19.45-11) = 2.3
Are natural, not dyed ethiopian opal also floureszent?
Some great information. Some of the Wello opal looks great, but I always stay away from the dyed ones. Will the Wello opal weigh in water be affected by the amount of water it contains already? Just the ethiopian opals absorb water easily.
Wello is awesome opal but fakes and to much water in some, spook me away.
