Sorry to hear about your bad dreams. I have no experience with AAA Jade Shop so I can't comment about them.Has anyone brought from Aaajadeshop from Etsy?
I brought a bangle, listed as A grade jadeite with opaque translucency and paid $160 AUD. I’m happy with it but I have been having terrible dreams ever since I have been wearing the bangle for a week. My aunt said the bangle probably is “dirty” meaning it may be treated or have been a pass off. Aunt also said that the bottom grade A grade jadeite would still cost around $300 AUD.
Anyone else have experience with the Etsy seller?
I have bought from both UJ and Jadeite Room and both sell Grade A jadeite. I have always found UJ pricey and Jadeite Room was lower priced for same quality last year when she first opened her Etsy shop. Now I find prices similar in both and like was said, Ling's prices have increased over time, especially if someone favors a bangle (posted about that before) so I am always careful not to do that there. Both will send lots of pictures and answer questions quickly if you ask and you do have the peace of mind that your bangle is the real deal from both.
Ling sends all bangles with a certificate, while Nandar only certificates items over $3000 US if you care about a certificate. Either way the bangles are Grade A.
As for bargaining, my experience is the opposite from what was said above. Nandar is no negotiation (for me) while Ling has been known to reduce the price if people just missed a sale for example. Maybe that's just me and doesn't hurt to ask

Nandar discloses imperfections (like cracks and rough spots) in the description, while the descriptions at the Jadeite Room are rather lacking (does not list the width of the bangle for example) and you need to ask for those details. Lower priced bangles are likely to have cracks (nothing bad, in my experience but if you don't ask, a cheaper bangle is likely to have imperfections) in both.
Shipping is very fast for me from both. Ling took 2 business days flat to get my order to west coast US in the past month and UJ took within a week. I get the regular shipment and don't pay for express shipment from either.
Bottom line: both are good sellers. UJ has always been very reputable and Jadeite Room is the newcomer on the Etsy scene with good products and customer service, perhaps still figuring out the pricing. I compare bangles from both when I am looking for something.
Good luck with your jade!
