garnet

garnet An important rock-forming mineral group, with the general formula X3Y2Si3O12, where X may be Ca, Mg, Fe2+, or Mn and Y may be Al, Fe3+, or Cr3+; the main minerals are grossular (X =Mg, Y = Al), pyrope (X = Mg, Y = Al), almandine (X = Fe2+, Y = Al), spessartine (X=Mn, Y=Al), andradite (X = Ca, Y = Fe3+), and uvarovite (X = Ca, Y = Cr3+), and there is continuous chemical variation in the group; an unusual variety called hydrogrossular Ca3Al2[SiO4]2[SiO4]1 − m (OH)4m has hydroxyl ions in the structure and is found in the rare rock type rodingite; sp. gr. 3.6–4.3; hardness 7.0–7.5; colour very variable depending on its chemical composition, and can vary from shades of deep red-brown to almost black, green, white, yellow, and brown; usually vitreous lustre; crystals cubic, with the most common form being dodecahedra; no cleavage; found in high-grade metamorphic and igneous rocks, in beach sands, and alluvial placers. Transparent pyrope crystals may be used as gemstones, but garnet is more generally used as an abrasive.

Garnett, Henry

Henry Garnett (gär´nət), 1555?–1606, English Jesuit. He was converted to Roman Catholicism and in 1575 became a Jesuit. After some years on the Continent he returned as a missionary to England (1586) and became superior of the English Jesuits. He is principally remembered as one of the priests accused of taking part in the Gunpowder Plot. Garnett admitted to knowledge of the plot as confessor to two of the conspirators, was convicted of treason on confusing evidence, and was executed.
