Many disaggregated olivine and metal fragments were recovered along with a larger metal-rich specimen nearby. All of the material was purchased by Ziyao Wang in October and November 2020, and the Meteoritical Bulletin records the main mass as held by Ziyao Wang. It was classified by A. Irving at the University of Washington and P. Carpenter at Washington University in St. Louis, and reclassified as an ungrouped pallasite in MB 114 following further mineral, trace element and oxygen isotope work.

I cannot say enough wonderful things about my experience with Treasure Coast! I purchased a lunar piece as a special gift, and their customer service went above and beyond to make it even more meaningful. After learning the story behind my gift (it was for my 1 year wedding anniversary), they surprised me by including the sweetest personalized card that said “Love you to the moon and back” with my name on it. It was such a thoughtful, unexpected touch and genuinely made the whole experience feel special. The lunar piece itself was wonderful, but the care and kindness they put into my order is what really stood out. This is the kind of customer service you remember. Highly recommend! 🌙❤️
Super great communication with the seller. All documentation for customs was correct and everything went super fast and smooth. The chondrite is exactly like shown on the seller's web.
A beautiful chondrite specimen, perfect for any collection. As always, Bryan is incredibly kind and helpful when answering questions or providing explanations about the specimen; he is also very pleasant to chat with, beyond the transaction itself. I highly recommend buying from him.
Received a Gyarub Zangbo and had a great experience. Brian was very responsive and guided me through the process. The piece is beautiful and will absolutely be a return customer!
An authentic piece of the moon for my small and humble meteorite collection. The piece is very accurately described with a COA attached. Highly recommended.
A truly positive experience; the products are authentic and truly interesting. Communication with the seller was excellent, and he was open to any questions or concerns about the items for sale. If you're looking to buy meteorites, he's the right seller. Highly recommended!
Ordered a lunar meteorite for my daughter to take to school during space week, it was a hit! Being able to hold a piece of the moon while teaching kids about the solar system is a fantastic way light the spark of curiosity in the class. The product itself was authentic, beautifully presented, and cherished by my kids. Highly recommend TCM!
