he's crazy like the moon bats he fervently believes are real, but I can listen to akroyd talk all day. he had his geology and water source info wrong though. the water is from the Wisconsinan glaciation, not glacier. the ice mass was the laurentide ice sheet. the diamonds are turning yellow because of sediment in the liquid settling behind them and changing the way light shines through them. easily cleaned in a sonic cleaner.
