NWA 6507, CR2
While perusing ebay one day, an armored chondrule caught my eye. The 5.1 gram stone was completely fusion-crusted and resembled a dull black lima bean. The main mass weighs a little under 4 grams, and is the least weathered CR2 I’ve seen from Northwest Africa.
Here’s the Meteoritical Bulletin writeup:
As can be seen in the second image, the type specimen was removed such that the armored chondrule was saved!
