Why did my well opal turn yellow?

Hi Karen,
Thanks for your question. I have a good deal of experience with Wello Opal from Ethiopia.
After about 1 - 2 years the colour will fade , but before that  many stones turn a mucky yellow colour . Truth is that they treat the stones in oil of some sort to enhance the brilliance  of colours . This is not the case with any  Australian Opal . So put simply your stone has been treated . Sorry to hear about that ... They do  look lovely when you first buy them ...but that just dont last .hope that helps  best regards Rod

all info pertaining to australian opals and opal fields is ok. online valuations is difficult but not entirely impossible. Photographs of stones should clearly show weight in carats and scale in mm. naturally photographs of opals are the hardest thing to take as a slight shift in direction displays a new colour or plane


Born into a pioneering opal family , now 48 yrs old , visited every opal field in australia, seen some of the finest stones ever produced . Sold high quality gems to japanese collectors and europeans and Americans
