我通过k - 12教育不断被告知,钻石是一个产品的碳,时间、压力和温度。如果这是真的,什么是阻止人构建一个高压,高温系统和倾销石墨,使数以百万计的钻石吗?看来我这里列出的具体策略是:https://en.wikipedia.org/wiki/Synthetic_diamond High_pressure.2C_high_temperature。但这是在文章“人造金刚石”。How can one tell a difference between a synthetic diamond and a "real" diamond? What is stopping someone from making these HPHT machines and making tons of money? Update: I watched the BBC special on synthetic diamonds (https://www.youtube.com/watch?v=5d2WebdMpBQ) and De Beers shows you can tell the difference between synthetic and real diamonds by their reaction to UV radiation. I am still interested in how I can make a DIY diamond if anyone has details on that. And to make this more on topic, how best I can simulate the Earth's formation of diamond? Why is the Earth's formation of diamond different from these HPHT and CVD diamonds?
