- 4.4 × 2.9 × 2.1 cm – Miniature specimen (fits into a 5 cm cube)
Hibonite is a complex oxide nominally comprised of primarilly calcium and aluminum. Minor impurities of iron and titanium of different valences lead to an electronic charge transfer, which manifests as black coloration. Curien et al. (1956) named the mineral in honor of Paul Hibon, who discovered the mineral. Hibonite here forms thick tabular crystals to 9 × 7 mm in marble. This is a rather unusual specimen in that hibonite has matrix.
From the collection of E.R. Laskowski (1949-2020). Laskowski acquired this specimen from Tropic Stone in 2002; labels from Laskowski and Tropic Stone accompany the specimen.
