Wow! So now when we see pistachio pearls, it is possible they were color treated.

Another reason to buy from reliable vendors.

I suppose the problem is that many wouldn't know the pearls had been dyed when they bought them, it looks like this has been going on for awhile.

Interesting article, as long as the treatment is stable...I wonder if treatments are applied to other Tahitians pearls to obtain other desirable colours and overtones.

 

[Icyjade]

Makes me wonder too...

In the article it does say that most Tahitians are only rinsed and "lightly tumbled" before entering the market. I don't have an issue with treatments, as long as they are properly disclosed. Great article, and really quite informative on the processing of these pearls!

Nice to know they are disclosing! Really good article. Thanks GG.

Figure 1 the colour of the pearls is very artificial looking.
