If I had a business I would do a mining company that mined for diamonds in Kansas. I chose Kansas because it has a huge diamond field in it. It also has multiple opal mines that try to mine opal. I could also go to Australia and start a business there, too, and mine opal, not diamond. Either way, I’m good at both science and mathematics so I’d be a good candidate for it. The buyers of my company would get cheaper prices than other companies and they’d get better gems. Besides, I’d make money. Therefore, a mining company is a win-win solution for everybody, no matter where I set up my company!
