Provenance

Gyarub Zangbo was found in October 2020 by G. Tulga during exploration on the Qinghai-Tibet Plateau, in the Qiangtang uninhabited area northeast of the Gyarub Zangbo river in Xizang, China. 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. This 226.95 gram slice was acquired by Treasure Coast Meteorite Co. and 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! 🌙❤️

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!
