Currently the artificial production of diamond is very expensive because it consumes large amounts of energy in order to produce a single diamond. Here, we propose a new type of press based on the intensification of the gravitational acceleration. This Gravitational Press can generate pressures several times more intense than the 80GPa required for ultrafast transformation of graphite into diamond. In addition, due to the enormous pressure that the Gravitational Press can produce, the "synthesis capsule" may be very large (up to about 1000 cm3 in size). This is sufficient to produce diamonds with up to 100 carats (20g) or more. On the other hand, besides the ultrafast conversion, the energy required for the Gravitational Presses is very low, in such a way that the production cost of the diamonds becomes very low, what means that they could be produced on a large scale.
