Something on the order of 2500 tonnes of gold is mined each year.
one tonnes= 1000kg therefore 40 tonnes is 40x1000=40'000kg
Approximately 130 million carats of diamonds are mined each year, although this figure can fluctuate based on market demand and mining conditions. The production is primarily concentrated in a few countries, with Russia, Botswana, and Canada being the largest producers. The total value of diamond production often exceeds several billion dollars annually, reflecting their status as highly sought-after gemstones.
4.46429 tonnes.
Divide the kilograms by 1000 to convert to metric tonnes.

According to the wikipedia article about germanium, about 118 tonnes of this element were produced worldwide in 2011.
Any diamond -- man made or mined -- is valued according to its cut, clarity, colour and carat weight. A man-made stone will cost significantly less than a mined diamond when both are similarly described.
142,000 tonnes of copper per year
Approx. 2 700 000 tonnes, up to 2011, in all the world.
Both kind of diamond are made from carbon. Mined diamonds are formed by Mother Nature; manufactured diamonds are formed by machines in a laboratory. Both rate 10 on the Mohs scale of hardness. A natural diamond will be much more highly valued than a man-made diamond, given that both are gem-stone quality. As with mined diamonds, most manufactured diamonds have industrial applications, and are not used as gemstones.
Diamond studs vary greatly on the size and clarity of the diamond itself and even factors that include where the diamond was mined. On average a rather small diamond stud can be purchased for around 50 dollars. Specifically a 1 carat diamond stud can average around 1,000 dollars.
Between 13 tonnes to 15 tonnes
45,000 tonnes (metric tons) is 99,200,000 pounds.
Depending on the quality of diamond you want, you can pay millions per carat for a gem-quality diamond, or you can purchase a bag of industrial diamonds for about the price of a latte. About 80% of all diamonds mined are industrial diamonds.
