Hi Mandy, Caitlin and All,
I can wholeheartedly recommend Wildflower Hill. I would have mentioned her before, but I thought you were focusing on pearls only. Her pearls are usually, but not always, part of a combined set. I have dealt with her for I think about 3 years, and found good quality, reasonable cost items.
I do recommend any time you purchase dyed pearls, to carefully check and see if they need washing before using. Sometimes there is an excess of dye, and the pearls even look better when washed. I mostly use a little dish soap and toothbrush. Caitlin, have you had experience with this??
Also Caitlin, I will expect to see a photo soon of the faux faux Lop Noors in a glorious necklace!! Of course you won't have to do a dye test on those!!
