Tourmaline briolettes

[dkata]

I've just bought a new pearl pendant, which has a small pink briolette, and I just fell in love with this kind of cut. I've found an Etsy seller, who sells seemingly exceptional quality, I've just found positive reviews. I don't want to post the link, I'm afraid someone might steal it.
The Seller claims, the tourmaline is from an old mine in Brazil , which is already closed. The price for this briolette's is about 166 USD. Do you think it's worth it?


The size of the briolettes is 4*5.1 up to 4.2*8.7 mm. The colors seem fantastic. The Seller has a few other beautiful items, like this:

The price of this item is 500 USD.

Could the experts give some advice and their opinion? Thank you in advance!

Be aware that photographs usually show more saturation than the stones have in reality, but yes, I think the clarity looks excellent, and some of the colors do. On the $500 one, the bottom half looks great, and the top half looks pretty muddy in color. If you like the colors in the $166 lot, yes, I think the price is fine.

Tourmaline - thank you for your reply! I'm really tempted to buy the 21 pcs. tourmaline! I would like to use them for a Marco Bicego Paradise inspired necklace.
