Abrégé

The improvements consist in the use, as raw material for obtaining the cultivated diamond, of tissues from the umbilical cord and/or the placenta of humans or animals, be these living or dead, subjecting said tissues to a carbonization process, which, as in the main patent, may be a carbonization by strong acid, a carbonization by Mufla oven or a carbonization by Bunsen burner, blowtorch or the like, the first case yielding the carbon by means of decantation, filtration or centrifugation and in the other cases by means of a mechanical dry scraping process or, optionally, wet scraping followed by drying.

Abrégé

The invention relates to a display case for gems, comprising two prismatic blocks (1 and 2) which are preferably made from methacrylate or another transparent material. One of the aforementioned blocks (1) serves as a container which is equipped with one or more housings (3) for the gems, while the other block (2) serves as a lid which is fixed to the body (1) using at least two pairs of permanent magnets (4-5). In this way, the gems in the case remain perfectly stable, are protected and can be seen from the exterior without having to open the case. According to the invention, the quick-actuating closure means are secure and effective.

Abrégé

The invention relates to a capsule and elements for synthesised diamond production. According to the invention, the capsule comprises a vertical gradient that is favourable to diamond growth, prevailing over any radial gradient, by means of heating discs which are disposed at the ends of the heating zone, with the growth conditions being carefully controlled. More specifically, control of growth rate enables improved quality control in large crystals. Another important novel characteristic of the invention lies in the use of a carbon source having a special design that is formed by cylindrical and conical voids (graphite, amorphous carbon, diamond or other) with a solvent metal with a number of gases which are introduced into the capsule. In addition, a nitrogen sensor is used to prevent the formation of nitrides, carbides and oxides which are detrimental to growth and said sensor is novelly positioned outside of the reaction zone.

The invention relates to a method of producing large diamond single crystals of different colours using carbon from the keratin to be found in the ectoderm of many living organisms. Carbon can be extracted from a human being by cutting off a lock of hair, carbonising said lock and subsequently subjecting same to a high pressure and temperature process.

Abrégé

The invention relates to a multi-anvil machine and, more specifically, to a cubic multi-anvil machine which is used to generate essentially-hydrostatic pressures and high temperatures in an industrial reaction chamber. Said chamber can be used to produce materials such as diamond, cubic boron nitride and other similar materials. The aforementioned conditions are obtained in a stable, efficient manner. According to the invention, the force is generated using short-stroke hemispherical pistons that are housed in hemispherical chambers. The number of moving components has been reduced in order to simplify and facilitate the assembly thereof during the operation of each work cycle.
