Seen at the 2017 Tucson Gem and Mineral Show, Hotel Tucson City Center, room 323 (Suzanne Morrison, Raining Rocks).
From the MetBul:
Physical characteristics - The stone (510 g) lacks fusion crust and has a weathered, brownish exterior; the interior consists of separated white and brownish clasts in a dark matrix.
Petrography - (A. Irving and S. Kuehner, UWS) Fragmental breccia composed predominantly of gabbroic eucrite clasts with some diabasic eucrite clasts in a sparse matrix of related debris. The grain size of pyroxene and plagioclase in gabbroic clasts ranges up to 1.4 mm. Primary minerals are exsolved pigeonite (with variable red-brown staining), calcic plagioclase (polycrystalline, birefringent), silica polymorph, ilmenite, Ti-bearing chromite, troilite and Ni-free iron metal; small amounts of secondary barite and calcite terrestrial weathering products are present.

Zelimir, as you know it is paired and they each have their own individual NWA numbers so TKW will never be combined. Suzanne is aware and was already working with her to resolved. Thank you though for your comment as I really want to update everyone that purchased a slice. |

As it appears that a second stone of 1635 g named NWA
8588, purchased by Steve Witt in July 2013, is most probably paired with NWA 7989, the question is "should both pieces receive the same NWA number in future ?
If this is decided (by whom ?), the TKW should become 2@2145 g |
