depends on how expensive it is . But I don’t really trust Chinese certs so I almost always get everything certified. I have a friend who bought a piece of jade that’s stated to be jadeite on chinese cert .
However , she brought it to Singapore gemologist to days it’s actually low grade omphacite with many impurities like amphibole . Granted , very pure omphacite is considered as a form of jadeite . But with the amphibole impurities , the Singapore gemologist says it would not be honest to certify it as jadeite at all .
For a gemstone to be classified as jadeite it must have at least a certain majority percentage of that content to be certified .
This is the stringency that Nanyang Gemologist in SG applies to their testing .
Some China labs can be very unscrupulous to certify such items even if they don’t qualify as jadeite to help sellers sell off something that can’t certify as jadeite .
After buying jade for sometime ,for many varieties , it’s not too difficult to tell grade A or not .
But for expensive varieties u already spend quite a lot on it , having a cert is not an appraisal of value, but does assure the jade buyer, what you are paying for etc ,good translucence etc
Good peace of mind for the next seller if u change your mind and intend to resell it .
For the cheaper varieties if u are sure if it’s authenticity , maybe not . And also for Nan Yang Gemology , (SG) able to get a verbal , for half the price of a printed cert . They have this flexibility because if an item don’t turn out grade A or if it’s fake , who wants to pay the full price for paying for something fake or inauthentic yes ?
so I always make sure to get a verbal at least even if it’s cheap . Just very anal about hearing it from the gemologist lol
Certifying jade doesn't really add any value to your jade pieces as far as I've read other than confirming that the piece you got is indeed untreated. But expensive pieces are definitely worth getting certification on since treated jades are the very thing that are trying to imitate expensive high quality jade pieces in terms of color + translucency.
Thank you Bernie and AJadecent Angle. Very informative. I don't intend to resell at all, but who knows what the future will bring. You guys have given me a lot to think about.
