Hello, I am looking for some insight into confusing but exciting world of Mystcraft. I was wondering with all the symbols out there, what would be the ideal age to mine with quarries? I want sapphires, rubies, emeralds, quartz, nether quartz, glowstone, and if possible even crystal. I know dense ores is unstable so that would not be an option. What symbols would I use to get a combination like this? Thank you!
