Thanks for your comments Henry James.
I just want to add that I have nothing against UJ. Although her items are overpriced in my opinion, she is flexible in allowing returns or exchanges, with no questions asked, and that's very important, especially if u are buying from overseas. Also, should any of your jade be tested to have any problems, she will readily refund u.
Just to share an example of my buying experience with her. I once bought a blue lavender bangle from her. It has an internal stoneline and one side of the bangle is thinner than the other, although not obvious if u don't scrutinize it too closely. I know that another seller would have priced this bangle much lower. But the colour is unique, its translucent and is overall very pleasing to me. Yes, I know the price is higher than what another seller would have quoted. But each piece of jade is unique and I know it is very unlikely I would find another piece exactly like this elsewhere. Although it has flaws (stoneline and uneven width), I decided to buy it anyway.
I know I paid more for the bangle than what it's worth. But I love the bangle, so it's an informed decision, like what Berniechocolate said. So in this respect, I do not say that UJ had taken advantage of me in anyway. It would have been different if I DIDN'T know that the flaws affected the value of the bangle and that it's worth less than the price and I was tricked into paying a high price for it, thinking that the price I got was fair or good.
Hope this makes sense [emoji4].
