See the difference with my previous post?
I had the case before of a big opal bought in good condition... I had the bad surprise to find it full of important crazing after some years of storage in its sealed box :-(
I read somewhere soaking it in oil may fill the cracks and improve the appearance.
I did it, using a cosmetic "dry" oil, in fact thinner than olive or other food oil...
It worked!!! I only had to repeat once the "treatment" done one year ago :-D
I must say I have another opal which showed no improvement at all...
So, I scraped carefully the glue remains, gave it a slight filing with my 4 steps nail buffer, then this huggie had its oil bathing for 2 hours.
A tissue wipe then a rub and polish with insect wax (used on jadeite by the Chinese)...
Et voilà! :-)
