Diamonds come from deep within the earth, yes, a natural source.
Diamonds come out of the ground looking like rough, unpolished crystals. They may appear cloudy, dull, and in various shapes such as octahedral or cubic. The raw diamonds have a rough texture and must be cut and polished to reveal their natural sparkle and beauty.
Mostly, natural diamonds come from deep within the earth.
Crystals are solid materials with a regular, repeating atomic structure, whereas diamonds are a specific type of crystal composed of carbon atoms arranged in a diamond lattice structure. Diamonds are prized for their hardness and brilliance, while crystals can come in a variety of shapes, sizes, and compositions beyond just carbon.
All natural diamonds come from the earth. They are mined in Canada, Australia, and Africa, Brazil, India and in other locations.
Almost 50% of all diamonds were mined in Africa. One hundred percent of all natural diamonds come from the earth and are found on every continent, except Europe and Antarctica.
There are over 300 shades of colour that natural diamonds come in including pink, black, red and yellow. This is because of mineral impurities and lattice defects in the diamond.
Natural diamonds come in all the colours of the rainbow. As well, there are many shades of 'white' diamond.
Brown diamonds are the most common of coloured diamonds found. Chocolate is simply the name of one of the shades of natural brown diamonds. Lab-created diamonds are generally 'white' diamonds.
Diamonds -- as are all natural minerals -- are as old as Mother Earth. All continents except Europe and Antarctica -- so far -- have been identified as sources for diamonds. Since diamonds have been part of human history for about 6,000 years, it's not possible to identify exactly which human in which location first picked up a shiny rock that was identified as a diamond.
All diamonds are erupted to the surface of the earth by volcanic pipes. Exceptions are diamonds that arrive on earth from unknown sources in space. Diamonds are found on every continent on earth except Europe and Antarctica.
Natural diamonds that erupt to the earth's surface were formed with the earth. Diamonds that come to earth from space may have been formed before earth: that research hasn't been documented to date.
Crystals most commonly form from a saturated solution, not from evaporation at the crystal surface. The propensity to crystallize varies according to the substance.By suspending a string in a concentrated solution, you may form good crystals yourself. But be patient and do not disturb your experiment.Compounds containing silicon have a high propensity, hence the majority of our gems. Indeed, even dry sand is known to form sand crystals, that crudely resemble quartz crystals. [Quartz has a high natural piezoelectricity.]Huge natural crystals are known formed from calcite. These are large compared to a human being!The actual crystal form is due to the position of charges on the surface of the particular molecule. Common salt is a good example of this. Diamonds are a very peculiar case, but natural diamonds don't often demonstrate clear faces.
