Provenance

Northwest Africa 17919 was found in 2024 in the Tindouf region of Algeria and purchased from a meteorite dealer. It was classified by J. Garcia at ADARA under the work name BMD 020 and published in the Meteoritical Bulletin, MB 114. The Bulletin records the classification as H6 S3 W1, determined from metal content, chondrule diameter and magnetic susceptibility, and notes that classifications made by magnetic susceptibility after Rochette et al. (2003, 2012) carry larger than normal uncertainty. The Meteoritical Bulletin records the remaining mass as held by Brian McDonald of Treasure Coast Meteorite Co., IMCA Member #3323. This 488.00 gram individual is that remaining mass and is offered as a classified specimen.

Let customers speak for us

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.

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!
