Pink diamonds have sales on the sidelines

This sale is in addition to "Pink Star" and "Graff Pink" on the podium of the most expensive pink diamonds in history. Each year, the renowned GIA (Gemological Institute of America) laboratory evaluates diamonds, less than 5% of which are pink. Among these, extremely rare are those who can have the hue certified "Fancy Vivid", the highest saturation.

Diamonds in a battery?

Who said that diamonds only dream women and only work in the world of diamond jewelery? Scientists are also very interested in these times. Indeed, the University of Bristol has developed, at the experimental level, a diamond capable of producing energy. What turn a diamond into a battery with inexhaustible life.

Without going into too technical details, the idea seems very interesting from every point of view. The principle is to use radioactive gases, from nuclear waste, to turn them into an artificial diamond. We know that this material is one of the purest so one of the strongest that can be made. The radioactive material must then be placed inside the diamond thus formed so that it produces energy. And here is a diamond transformed not in a diamond jewel but in battery.

Where this principle is revolutionary is that it allows the use of nuclear waste by imprisoning them in a material that does not let the radioactivity spin, so perfectly without fear for man. In addition, depending on the particles used, it can reach an autonomy of several thousand years. The craziest dreams of science fiction can become reality with the control of an energy certainly still expensive to produce but inexhaustible later.
