<prompt> Human: I want to diversify my assets and was wondering if anyone has any strong opinions on whether I should or should not invest in precious metals. Im obviously interested in gold but was wondering if investing in silver, platinum, or another precious metal would also be a good. Is there anything specific I should look for when purchasing a specific metal?Is it true that if the stock market busts, gold is usually a safe haven?Im also interested in gem stones but I think that requires more knowledge about cut and quality.  <response>: By definition you cant invest in precious metals since they cant generate any income, you can speculate in precious metals since the only potential profit is from buy-low sell-high.Speculation is extreme high risk and I would advice against it, and if you look at the long term track record gold performs pretty shoddy, adjusted for inflation gold is worth less today than it was in 1980...
