TKW 1800 grams. Observed fall 4 June 1828, Virginia, USA.
  
Frank writes:
The pictured, nearly two century old specimen, is a 2.83 gram crusted fragment. Richmond was seen to fall and recovered immediately from a one-foot-deep (30 cm) impact pit. It was partially covered with a black fusion crust and, as shown on an accompanying photo, a secondary fusion crust. Most of the meteorite is predominantly olivine, orthopyroxene, and lesser amounts of troilite and Fe-Ni metal. The fragment measures 18 mm across in the greatest dimension.
Photo 1 shows a freshly broken surface.
Photo 2 shows an original surface coated with an incipient fusion crust. Note the several spherical chondrules that reach ~1 mm in diameter. One is near the center of the fragment, and two others are seen along the edge of the fragment, one at 10 o'clock and one at 2 o'clock.

Hey Paul, I have to disagree with regard to the Met.Bul. entry. They list Richmond as an LL5! |

Hmmm?! Both the 4th and 5th editions of the Catalogue of Meteorites list Richmond as an L5 chondrite! |
