It's possible that a raw diamond has facets -- often the crystalline structure can look like a pyramid -- or two pyramids joined at the base. Then, there would be up to four planes which could look like facets.
Facets -- in the conventional, gem-stone sense -- are cut, angled and juxtaposed other facets, based on the planned cut for the raw stone.
Diamonds come from deep within the earth, yes, a natural source.
Mostly, natural diamonds come from deep within the earth.
Some gem-quality diamonds come from the ground in the shape of two pyramids joined at the base, with four 'faces' on each pyramid. This is an ideal, natural diamond. Very few natural diamonds are found with this ideal shape. (Diamond as a precious mineral was probably first admired based on a human picking up such a stone, more than 5,000 years ago.) Most diamonds as they are found, are mis-shapen with many faces. As well, only 25% of mined diamonds are of gem quality, the remainder are considered 'industrial diamonds' not suitable for processing as gemstones.
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.
Blue diamonds are mined in various locations around the world, including South Africa, India, Australia, Brazil, and Russia. The most famous blue diamond mine is the Cullinan Mine in South Africa, which has produced a number of large and valuable blue diamonds.
No, raw uncut diamonds do not come in the shape of a round crystal ball. Raw uncut diamonds typically have a rough, irregular shape with many facets and angles. The round shape of a crystal ball is usually achieved through cutting and polishing.
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 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.
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.
