Black Diamonds is a sombre sculpture that expresses anger at the final round of coal mine closures that began during Margaret Thatcher’s leadership.The closures marked the death knell of the 2000-year-old British mining industry. Black Diamonds expresses horror at this wanton destruction, and solidarity with those who fought to save their jobs and communities. A series of life size black satin crows, a symbol of death, hover over piles of coal on blackened plinths, while a reliquary reveals a red satin interior filled with coal – Black Diamonds. A banner, an evocation of those traditionally carried by trade unionists, lists the names of more than two hundred pits closed as a result of this action. There are now three coal mines in Britain, two under threat of closure, although 40% of British energy needs are derived from imported coal.
