Nizhoni is deliberately misleading buyers by posting photos from third party websites of items they pretend to be selling but don't have in their possession.

I bought a handmade vintage pendant (heart shaped row of turquoise, Dan Dodson) at Nizhoni Traders LLC online, and asked for an updated photo in daylight to confirm the type and colour of turquoise in the pendant. Nizhoni refused to send a photo and insisted that the pendant was identical to the sales photos.
Once the pendant arrived, it was not the one from the sales photos, but a completely different pendant. Same design, but not the stones from the sales photos.
It turns out that Nizhoni had lifted the sales photos from an auction website instead of taking their own photos of the actual item they put up for sale, so they knew exactly what they were doing. Nizhoni is deliberately misleading buyers by posting photos from a third party website of an item which they don't have in their possession.

How it's going:
Paypal is requesting that I return the item to get a refund of the payment. So the return shipping will be out of my own pocket. I already paid steep import taxes out of my own pocket. But the return shipping is very expensive for privates in my country, so essentially it'll cost me half of the price of the pendant in return shipping and import taxes, which Nizhoni will not refund.
So should I pay even more to return the item?

I recommend to stay away from Nizhoni Traders. Don't buy from them. There are plenty of decent and honest turquoise sellers out there. Nizhoni is not one of them.

Edit:
I ended up keeping the item because I had to pay for international shipping myself, and because I wouldn't get all the money back I had paid for import tariffs. I would've been out of pocket even if I returned the item.
I wish I could upload photos of Nizhonis sales photos and photos of the actual item I received, which was not identical. The items are clearly different. But uploading photos unfortunately isn't part of Trustpilot's service.

In short — Nizhoni DID send me a different item than the one they sold to me on their website.

Nizhoni's reply to this review where Nizhoni accuse me of fraud and stealing is straight up slander.
And Nizhoni never replied to me directly about this matter, and they never offered to cover the return.

Please understand that this is a genuine review reflecting my personal experience with Nizhoni. And Nizhoni has proven to be dishonest, unresponsive, and slanderous.

I recommend staying far away from Nizhoni Traders.
