The Tisserlitine Raw Collection - Lunar Meteorite Necklace and Pendant I .925 Silver Jewelry
The Tisserlitine Raw
On Offer: Pendant hand fashioned from the hydrothermally altered lunar meteorite Tisserlitine 001. The center stone for this pendant is not shaped after cutting like most of our pendant center stones. Instead we are leaving these in a more natural state and set them with minimal additional stylistic input to compliment the organic and complex patterning created by the hydrothermal alterations.
The Tisserlitine 001 lunar meteorite is a beautiful brecciated lunar meteorite, with a vey complex interior in comparison to many feldspathic breccia, due to terrestrial alteration by hydrothermal processes prior to being discovered.

Tisserlitine 001 21.325°N, 0.729°E
Find: 2019 Dec
Classification: Lunar meteorite (feldspathic breccia)
History: Beginning in December 2019 many similar dark stones were found together in the Kidal region of Mali, close to the border with Algeria. One very large stone (40026 g), another stone (4037 g) and 44 smaller stones (combined weight 3642 g) (total weight 47705 g) were purchased by Aziz Habibi in January 2020 from an Algerian dealer and subsequently acquired by Darryl Pitt. Independently, ten other stones of the same distinctive material (combined weight 8536 g) plus many smaller fragments (combined weight 1169 g) were purchased by Mbark Arjdal in February and March 2020 from a relative of the same Algerian dealer.
Physical characteristics: All specimens (many of which have a flattened slab-like form) lack fusion crust and exhibit medium-brown, "knobby" exterior surfaces. Interiors of stones have an overall tan to pinkish hue with obvious light gray, dark gray and whitish clasts plus some visible small grains of metal.
Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Two separate endcut specimens were studied. Both are samples of the same breccia material, composed of mineral clasts of anorthite, olivine, pigeonite, subcalcic augite, augite and orthopyroxene, plus sparse lithic clasts of spinel troctolite, set in a fine grained microvesicular matrix containing accessory altered kamacite, troilite, taenite and pentlandite. Secondary calcite is present pervasively in one of the two specimens studied and in places may be replacing original glass. Olivine grains in both studied specimens have been partially replaced by inhomogeneous phyllosilicate-rich assemblages, which apparently are hydroxylated (as evidenced by systematically low oxide analytical sums of 88-90 wt.% and absence of measurable F and Cl), and which are very Mn-deficient (yielding very elevated FeO/MnO ratios in the range 150-250). Troctolitic clasts are composed predominantly of anorthite and olivine with accessory Cr-pleonaste, low-Ca pyroxene and/or higher-Ca pyroxene.
Geochemistry: Olivine (Fa17.3-32.1, FeO/MnO = 76-100, N = 15), anorthite (An95.4-99.0Or0.2-0.0, N = 7), pigeonite (Fs18.2-26.8Wo12.4-4.7, FeO/MnO = 47-54, N = 6), orthopyroxene (Fs16.0-21.6Wo2.2-3.7, FeO/MnO = 51-66, N = 4), subcalcic augite (Fs15.9Wo31.0, FeO/MnO = 41), augite (Fs7.6-7.9Wo42.9-45.6; Fs13.8Wo38.9; FeO/MnO = 36-48, N = 3). Troctolite clast: olivine (Fa18.2-21.2, FeO/MnO = 84-92, N = 4), anorthite (An97.7Or0.0), pleonaste (mg = 0.721, cr = 0.093).
Classification: Lunar (feldspathic regolithic breccia, partially hydrothermally-altered).
Specimens: 37.6 g in the form of two polished endcuts at UWB; remainder with DPitt and Mr. M. Arjdal.
