Do you see countries keeping diamond in the treasury depository?

Well, my point is that we are comparing between diamonds and golds, Am aware that some rare diamond are able fetch unbelievable price in the market however thats if you are rich enough to get those. As for golds, you can say that its equivalent to money in its way, also it is better to bet on gold if in case monetary system fails and it is more steady in terms of value in the market.
