Interesting and Little-Known Diamond Facts
Everyone knows that diamonds are the hardest natural substance in the world, but there are many things that have to happen to make them this way. This article will look at some diamond facts that you may have never heard before.
Diamond Facts: The Unique Properties of Diamonds
Diamond is composed of carbon aligned in a cubic crystal form. This four atom form gives diamond its amazing strength. Diamond has an adamantine luster with a high refractive index, 2.42 to be exact. Diamonds are usually known as being almost colorless, but they can come in yellow, brown, blue, green, orange, red and black colorations.
While these diamond facts are interesting, there is far more to this gemstone than its physical properties. One of the least known diamond facts is how old it is. Diamonds may be up to three billion years old and in general are far older than the rock in which they are found. They begin there existence far below the earths surface at a depth of around three hundred and twenty miles.
From there the diamonds are transported to the surface via kimberlite and lampriote pipes. These rock formations form a link between surface rocks and the Earth's mantle. One of the more unique properties of diamond is that it can burn. It is composed entirely of carbon, and if exposed to enough heat and oxygen it will ignite. It does take a significant amount of heat, around a thousand degrees Fahrenheit, to make this happen. Conversely, a cubic zirconium will not burn.
More Than Just Diamond Facts
In addition to the factual information presented above, there are many other diamond facts that are based more in myth and legend than pure scientific fact. Diamonds have been seen as a status symbol throughout history with origins dating back to the pre Christian era. Diamonds throughout history have symbolized purity and invincibility, as evidenced by the origin of the word diamond from the Greek name, adamas, meaning invincibility.
Ultimately, however, these properties come from the physical properties of diamond. Even before science was able to fully analyze the properties of this gemstone, ancient people recognized it for its rarity and incredible toughness. For thousands of years people have recognized that the properties of this rare mineral are exceptional. By reviewing diamond facts one can understand why this gem is so valued and so common for use in jewelry, decoration, and everywhere else to symbolize longevity and wealth.
