Diamond prices are down 60% since a 2011 high, and they are still falling. It's not all down to lab-grown diamonds, demand is down too, especially in China.

No one can lab-grow gold yet, so its rarity and scarcity protect its value, but that will end too. It's just a question of when. China launched an asteroid touch-down mission this week, which will make it the 4th country/region to do so, after Europe, the US & Japan.

How soon will it be feasible to mine asteroids? Who knows, but a breakthrough in space propulsion might mean the prospect happens quickly when it does. It's possible gold has twenty years or less of being high value left.

Diamonds are rare on the surface of the earth, and their discovery therefore costs on the average much labour-time. Consequently, they represent much labour in a small volume of space. Jacob doubts that gold has ever paid its complete value. This holds true even more for diamonds. According to Eschwege, by 1823 the complete yield of the eight-year old Brazilian diamond-diggings had not yet amounted to the value of the 1½ year average product of the Brazilian sugar or coffee plantations. Given more richly laden diggings the same quantum of labour would be represented by more diamonds and their value would sink. If one succeeds in converting coal into diamonds with little labour, then the value of diamonds would sink beneath that of paving stones.

hmm sounds like someone has a theory of where value comes from

This reminds me of how someone I used to know once literally pointed at diamonds to "disprove" the labor of value and is like "Marx never considered diamonds" and I'm just like phoenix-objection-1 phoenix-objection-2 at that exact paragraph.
