Trivia

 * Nether Quartz appears to be quite common in The Nether, but in reality, is about as common as Iron Ore in the overworld, each spawning approximately 70 ores per chunk. What makes it seem more common is that it can spawn on any layer within The Nether, and the fact that the Nether has more exposed blocks than an overworld cave.


 * Jeb recently released a snapshot supporting Nether Quartz to Diamond conversion via smelting. Considering Nether Quartz common appearence in the Nether, it is estimated that player could obtain somewere from 1-3 stacks of diamonds in half-an-hour.
