Bye-Bye Diamonds

15 novembre 2020


Version Française

Ce qui devait arriver est arrivé. Les diamants ont été un moyen d’investir et balader ses investissements discrètement. Cette voie semble avoir perdu une bonne partie de sa pertinence, les diamants naturels ne seraient plus l’unique source de cristaux de carbone.

Vu ce reportage sur Sky mais il est aussi passé sur BBC et pas seulement. Cela ne semble pas du pipo, au plan technique, la description du process semble tenir la route.

Sans jouer dans la cour des conspirationistes, deux points me gênent un peu :

  1. Dans ce reportage, le carbone provient du CO2 prélevé dans l’air.
    Il existe des sources de carbone plus aisées à séparer du milieu.
  2. Les diamants présentés sont taillés.
    Un diamant brut de sortie de four aurait été plus crédible.

Si le reportage n’est pas un hoax et que le process existe, pour le moment la production est encore faible mais il n’y a aucune raison qu’elle reste faible.

Diamonds were for ever, not anymore. Et oui, l’avenir, c’était mieux avant.


US English version

What had to happen has happened. Diamonds used to be a way to invest and to wander ones investments discreetly. This path seems to have lost much of its relevance as natural diamonds seem to be no longer be the sole source of carbon crystals.

Saw this report on Sky but it was also on BBC and not only. This does not seem like a hoax. Technically, the description of the process seems to hold up.

Even though I am not playing the conspiracy game, two points bother me a bit:

  1. In this report, carbon comes from CO2 isolated from the atmosphere.
    There are sources of carbon that are easier to separate from the medium.
  2. The diamonds shown are cut.
    A raw diamond from the oven would have been more credible.

If the report is not a hoax and the process exists, for the moment the production is still low but there is no reason why it remains low.

Diamonds were for ever, not anymore. And yes, the future was better before.
