Hello and thank you for viewing my listing. Today you are purchasing one rare end cut specimen of NWA 1232 Carbonaceous Chondrite CO3 Meteorite from Morocco. Gorgeous specimen with tons of chondrules and both lithologies view. This CO3 features 2 different lithologies separated by a sharp boundary: lithology A is a dark gray; lithology B is light gray. Both lithologies contain well defined chondrules set in a fine-grained matrix. Lithology A consists of 53% chondrules, 2% CAI's and 7% AOI's, whereas lithology B consists of 50% chondrules, 3% CAI's and 5% AOI's. Below is the data for NWA 1232. Excellent rare addition to your collection.

My catalog number is 1232-0126 and weighs in at 0.62 grams and comes with my card of authenticity for provenance. Remember, provenance is a must when collecting meteorites. I have designed a COA for NWA 1232, as I do with all of my classifications or specimens, I hold weight. The specimen you see pictured is the exact specimen you will receive. Each card comes with catalog number, weight and my signature of authenticity. Thanks again for viewing. Cheers!

Thanks again for viewing and my shipping is like this, the first is usually only $4.79 and .50 cents for each additional item, unless over 60 grams, then 1.00 per item.
