Diamond is still a very relevant material in many industries and it has a high refractive index making it a nice gem stone - but the prices jewelers charge are definitely due to DeBeers' marketing and market manipulation. If diamonds had this intrinsic value, the market for second hand diamonds would be much larger.

Yea, I remember selling my wedding ring for like $30 after it cost over $800.  The worth is entirely fake, I'll never fall for that shit again.
