@WestOz For new players to mine for gems, which include Sapphires, Rubies, and Diamonds, they have to go to one of the two mines, being copper or iron. At the copper mine, there is a chance to get copper ore, uncut sapphires, uncut rubies and gold nuggets. At the iron mine, there is a chance to get the iron order, uncut rubies, uncut diamonds and gold nuggets. Once the gemstones have been mined, there are two ways to cut them. The first way which is the most efficient, but also most expensive, is at the gem processor where you need to buy a license for each kind of gemstone for $400,000 per license. The second way is to go to Bunnings and get a hammer and a chisel, which can be used to craft a cut gemstone. One downside to the hammer method is that they are a one-time use, so if you are doing a lot of gems, it is slow and inventory consuming. Once the gems are processed, head over to the Gem Trader and sell them. The usual price for cut sapphires is $22,000 each. Cut rubies go for $38,500 and diamonds go for $62,500.
