    Packaging was some of the best I have had for minerals thank you very much for taking extra care! Shipping was good, and seller added combined shipping without having to ask which was nice. Seller was also very fast at adjusting shipping and sending quickly. Items were as described and the value was from a bid.

    Amazing seller, definitely top tier. They carefully packaged my item, it looks the same in person as it did on the listing. The item arrived quickly. I will definitely be buying from this seller again. Probably the most reputable seller I have conducted business with. I appreciate all the details they include with the packaging, such as where the gemstone was found. I got lucky with this piece, the seller honored the auction and its final price. I feel like I got a deal.
