Due to the highly condensed carbon structure of diamonds, the use of diamonds has gone beyond the decorative stage. The difference between naturally grown or developed diamonds and the lab-produced diamonds has puzzled the market of the precious miniature materials. The paper by Zhang et al. 2026 has demonstrated that at the tiny size of a nano-structure the typically found hard structure of a diamond brakes down. The size-dependent softening of the diamond at the nano-size is a puzzle, but has been resolved with the explanation that on the surface the atoms remain rather stiff, only the inner structure of the cristalline core does “wobble”. Hence, diamonds are still almost forever, unless you crush them with far too much weight or power.
