Gold versus Diamond, which would you like to possess and why?

Gold is a chemical element while a diamond is a form of carbon(an allotrope). Both of them are highly valuable and respected in every cardinal point of the globe. Gold is malleable and highly conductive while diamond is the hardest known substance that exist and a poor conductor. Personally, I would like to have both of them in my possession. From economic benchmark granular review, I will prefer gold to diamond because it is the backbone of any advanced economy with high resale value. On the other hand, as expensive as diamond the resale value carries a big ? mark.
