Splayed rosettes 0.5-2.5 cm in diameter of akrochordite thinly coating a fracture surface in granular, high-grade, brown willemite-franklinite ore. This is the best of several akrochordite specimens owned by the Franklin Mineral Museum and is notable for the large size of several of the rosettes; in most other specimens they are only 5-7 mm across (Dunn, 1995, p. 656). From the SPEX/Gerstmann collection, this specimen now bears the catalog number FMM-1916. This is from the 1979 find of akrochordite described by Pete J. Dunn in his 1981 paper; he states that only about 20 specimens were recovered.
