jewelry is always a bad investment unless you are paying right around melt for it like the we buy gold guys. there's a huge creator markup, and then the retailer markup on top of that. if you need it, like engagement or wedding rings, it is what it is. if you like it, then you see the value to the prices, but as an investment, no, there's better ways to buy gold. however if you bought gold jewelry pre 1980s, you did likely do really well. much less room on it since 2005 onward between bought and what it could sell for with the 250-300% markups that get added to the base component prices by the time it reaches retail.
