Hey all, I was wondering if you could give me some advice on this particular necklace (see pictures) as I'm torn between this set and Pearl Paradise's untreated natural hanadama necklace. I loved the way PP's pearls exhibit the fascinating overtones, but the luster in this akoya necklace caught my attention. The luster seems too good to be true, and I think they received extra treatments? I read somewhere that some treatments do enhance the luster but it makes the nacre so thin that the luster will wear off over time? If that's the case then I'd rather go for PP. What do you think?
