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.
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.
