Ceylonite

Ceylonite (first cited 1793) and pleonaste (first cited 1801) are dingy blue or grey to black varieties of spinel. Ceylonite, named for the island of Ceylon, is a ferroan spinel with Mg:Fe from 3:1 and 1:1, and little or no ferric iron. Pleonaste is named from the Greek for 'abundant,' for its many crystal forms, and is distinguished chemically by low Mg:Fe ratios of approximately 1:3.
==Composition==

The mineral ceylonite has the chemical composition of (Mg, Fe2+) Al2O4, putting it into a group of minerals known as the spinels, or the oxide spinels. The oxide spinels have a formula of the model ()()2O4; where () is commonly Fe2+, Mg2+, or Mn2+, and () is Fe3+, Al3+, or Cr3+.
