I would like to know the pastal shade colors of fresh water pearls which are apparently bead nucleated in China.
Does it comes in intense purplish hues?? I suspect treatment mainly due to the intensity of the color and uniformity. But supplier insist that its the new method they use to create these pearls which comes in ranges from 11 mm reaching upto 15 mm and there is no color treatment involved!!!
I am totally lost here... did I miss out on any important research which is ongoing?? How is it possible to creat a perfectly round bead nucleated fresh water pearl with great intensity!! in this case purple!!
When I view through the drill hole the bead nucleus rather dark layer (ring) ranging from greyish to deep yellowish. This confuses me more as the pearls on hand is intense purplish hue. What kind of treatment can they perform for these? Irradiation? Heat?
Also brings me to the question on how do we know if its fresh water bead nucleated or salt water bead nucleated? I cant find any relavant reference to this!
