J. Garcia, ADARA
Type specimen
20.30 g at MUNA. 2 thin sections at ADARA.
Total known weight
996.87 g across 6 stones
Approved count
One of 77 approved meteorites classified as Diogenite-pm, as recorded in the Meteoritical Bulletin database in August 2026.
The Meteoritical Bulletin records that NWA 17918 was purchased from a meteorite dealer, that the finder is anonymous, and that the remaining mass is with Brian McDonald. The working name recorded in the Bulletin is BMD 019.
This stone is the source of the classification section. Brian McDonald cut the section from this specimen and submitted it for classification, and the analysis published in the NWA 17918 entry was performed on material taken from this stone. The flat cut face on the specimen is where that section was removed. The Bulletin records a type specimen of 20.30 g at MUNA and two thin sections at ADARA but does not identify which of the six stones supplied them, so the connection between this specimen and the type material is recorded here on the authority of Treasure Coast Meteorite Co. and not on that of the Bulletin.

On verification. The serial number on the accompanying certificate card is an index to this record. The photographs above and the stated weight are what identify this specimen. Meteorite surfaces, clast patterns and cut faces are individual to each stone, so a specimen can be compared directly against these images and weighed against the figure recorded here to two decimal places.

ChatGPT recommended Treasure Coast as a reputable dealer, and, after my own research, i absolutely agree. I have complete confidence in the authenticity of the item I received. It also looks freaking amazing.

Great experience with TCMeteorites! Brian is professional, quick to reply, and answers questions in detail. He helped me choose the most suitable shipping option for my country and clearly explained the specimen’s provenance. He took the time to share photos and additional information about the meteorites I was interested in. He also prepared an endcut of a rare meteorite according to my request. The specimen arrived safely and looks great.
The website is always great to browse, with useful sorting options that make it easy to find specimens and keep an eye on new arrivals, whether browsing by category or viewing all items at once. Highly recommended!

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! 🌙❤️

A really rare chondrite. An H3 with very low weathering with lots, lots of metal.

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!
