The Crimson Diamond

I wouldn't normally be so specific about a puzzle, but that moment was less a Crimson Diamond and more a White Whale that I would hate to see anyone else chasing. Otherwise I think The Crimson Diamond is a beautiful piece of work, combining a love letter to the past with a modern implementation, all wrapped up in a mystery that may not have huge, shocking twists, but remains a page turner throughout. And there are bonus geology facts, too! Consider PLAYING THE GAME.
