Unique Fact About Diamond

Share on :

There's no denying that diamonds are a traditional symbol of romance and love. Why, a man needs a diamond ring to ask the woman of his dream to marry him, right? But was it always that way? Did you know that someone worked very, very hard to make diamond rings de rigueur in marriage proposals? Or that diamonds aren't actually very rare at all? Or that they make lousy investments?

A diamond is the hardest natural substance on earth, but if it is placed in an oven and the temperature is raised to about 763 degrees Celsius (1405 degrees Fahrenheit), it will simply vanish, without even ash remaining. Only a little carbon dioxide will have been released.

Diamonds are formed over a period of a billion or more years deep within earth’s crust – about 150km (90 miles) deep – and is pushed to the surface by volcanoes. Most diamonds are found in volcanic rock, called Kimberlite, or in the sea after having been carried away by rivers when they were pushed to the surface.

A diamond is 58 times harder than the next hardest mineral on earth, corundum, from which rubies and sapphires are formed. It was only during the 15th century that it was discovered that the only way to cut diamonds was with other diamonds. Yet, diamonds are brittle. If hit hard with a hammer, a diamond will shatter or splinter.

Well, what are the other facts about the unique Diamond?

Diamond has many colors

When thinking about the diamonds, may be a message that is in your mind is kind of beautiful white stone. As we all know, the white diamond is one of the most popular kind of diamond, while black diamonds are also quite popular for many people. Did you know that diamonds actually have a lot of colors like pink, blue, or even yellow. Not all diamonds are white. Impurities lend diamonds a shade of blue, red, orange, yellow, green and even black. Vivid blue, green and pink mined diamonds are the rarest. They are not the rarest gemstones, however. That title goes to a pure red ruby. Diamonds actually are found in abundance; thousands are mined every year. 80% of them are not suitable for jewelery – they are used in industry or in cheap rings. Although these colorful diamonds may not be quite popular, but it can give a unique impression for the wearer.

Besides used as jewelry, diamonds are also useful for other things

Yes, there are many benefits to be gained from the diamond because of its ability to cut other substances. Most people think that diamonds only used for jewelry only, as in rings, necklaces, or other jewelry. Though diamonds can also be used for a variety of other equipment, such as a knife sharpener, smooth equipment, glasses, or to cut other precious stones.

Diamonds are the most expensive precious stones

Everyone believes that diamonds are the most expensive gemstone in the world, such as Ocean Paradise Diamond. The Ocean Paradise is a diamond measuring 1.6 carats (0.32 g) after polish and was discovered in Brazil and currently owned by the Nahshonov Group. When discovered, it measured 6.43 carats (1.29 g). The Ocean Paradise is the second and one of the only natural diamonds known to the GIA to possess a blue-green hue (the first being the Ocean Dream Diamond owned by the Cora Diamond Corp., found in Central Africa), making it one of the rarest diamonds in the world.

Valuing Diamonds

Diamonds are graded by trusted institutions like the HRD or GIA based on several characteristics. While such a grading process is quite complex, it can be simplified to a few key factors. Although the blue diamonds have higher prices, but the color is not the main determinant of the price of diamonds. There is another thing that is also a consideration price of diamonds, first: clarity and second: carat weight.

Diamonds are priced per carat, according to their size and quality. Although the carat weight of a diamond is indicative of its size, it is not necessarily indicative of a diamond's quality.
