From: Dictionary of American Fighting Ships
An opaque and impure variety of quartz, usually red in color, used as a gem.
BAM-29, an Auk-class minesweeper, was launched by Associated Shipbuilders, Seattle, Wash., 20 June 1943; completed and turned over the United Kingdom under lend-lease 12 August 1944; and served in the Royal Navy as Jasper. She was returned to the U.S. Navy 24 December 1946 in England, and eventually sold to Greece, where she was apparently not used as a warship.
