The abundance of gold in the Earth's crust is estimated to be about 0.005 parts per million. That makes it one of the ten rarest elements in the Earth's crust. Gold is thought to be much more common in the oceans. Some people believe as much as 70 million tons of gold are dissolved in seawater. They also think there may be another 10 billion tons on the bottom of the oceans. So far, however, no one has found a way to mine this gold.
yes black diamonds are rare in this region
Kimberlite pipes are a common geologic feature where diamonds are found. These cylindrical volcanic rock formations bring diamonds to the Earth's surface from deep within the mantle. Diamonds are typically formed under high pressure and temperature conditions, and kimberlite pipes are one of the few mechanisms for bringing them to the surface.
Diamonds share the property of being a naturally occurring crystalline solid with a definite chemical composition, as all minerals have. Additionally, diamonds are formed in the Earth's mantle under high pressure and temperature, which is a common process for many minerals.
This is a question without an answer. What is clear, however, is that extracting diamonds from the earth is expensive and dangerous: diamonds are not as common as air or water, for example. It is not possible to determine how many diamonds there may be on earth, but it may be accurate to write that diamonds are not necessarily 'in abundance' on earth.
Man-made diamonds are often referred to as synthetic diamonds or lab-created diamonds.
The most common use of diamonds is for industrial tools, because industrial diamonds are the most common diamonds.
When describing diamonds, glass is probably not as common as ice.
Industrial diamonds are most common.
Most gem-quality diamonds found are about the size of a pea.
Brown diamonds are the most common colour of diamonds mined, of gem-quality. Only about 20% of all diamonds mined are of gem quality.
No, people say ROTATED SQUARES are diamonds - It's a common mistake. Diamonds are just rotated squares - NOT diamonds. Just remember that.
The common ingredient is - Carbon.
No. Although any diamond is rare, brown-coloured diamonds are among the most common gem-quality diamonds mined.
Most every diamond not identified as another colour is slightly yellow -- some are intensely yellow. However, Intense Fancy Yellow diamonds -- natural diamonds -- are not common, and are therefore more valuable than comparable diamonds without the intense fancy designation.
they both contain carbon
All forms of carbon.
