Ruby rings are made by combining a gold bar and a cut ruby. It is highly recommended you make a bank preset with 14 rubies and 14 gold bars, and a preset with 28 gold ore. You should bind these presets to quick presets 1 and 2. The process is fairly click intensive, and very tedious. With a portable forge, it takes 70 seconds to smith 28 gold ore into bars (getting enough material for two rounds of ring crafting), and the 14 ruby rings each take about 26 seconds to craft. This gives a fully cycle time of around 122 seconds, allowing 29 cycles per hour, giving 812 rings per hour.
