Two hour chunk mining sessions between y-20 and y-4 in the Misty Mountains, carving out literally every block within a set area. I personally mine in sets of 20x20 squares, selling half of any precious gems I find and keeping the other half. I generally can dig between ten and twelve 20x20 chunks in each set of two hours (while listening to podcasts). The extra cobblestone I store and keep for future building projects. I also sell any silver, copper, tin, Sulfur, and salt alongside the precious gems. Thirdly, I sell half of any iron and gold. This strategy stills leaves you with decent enough amounts of ore needed for other purposes while still leaving you with plenty of money (and negative Gundabad alignment).
