The sample (10 x 6 x 1 cm) is flat and has black fusion crust on all surfaces, with the exception of the B and portions of the W surfaces. The sample has been fractured into two pieces across its middle. The B surface is polished and has a mottled yellowish-red-brown appearance. Chipping of the specimens revealed a medium gray matrix with inclusions (<1 mm). The sample has a prominent (1 mm) weathering rind.
