What exactly is a diamond?
A diamond is a precious stone formed from an essentially colorless crystalline form of pure carbon. Interestingly, diamond and graphite are both pure forms of carbon. Diamonds are originally formed at depths of 140 to 190 kilometers in the Earth’s mantle.
Is Diamond a metal or stone?
Diamond, a mineral composed of pure carbon. It is the hardest naturally occurring substance known; it is also the most popular gemstone.

What is a diamond made of?
Diamonds are made of carbon so they form as carbon atoms under a high temperature and pressure; they bond together to start growing crystals.
Is a diamond a gem or Crystal?
In modern use the precious stones are diamond, ruby, sapphire and emerald, with all other gemstones being semi-precious. Another term used is habit, the form the gem is usually found in. For example, diamonds, which have a cubic crystal system, are often found as octahedrons.
Why diamonds are so precious?
The earliest recorded cultures used diamonds to portray strength, the value of love, and even instruments of magic. That value is likely due to a diamond’s natural strength and unique visual appearance in combination with its relative rarity. Even a low-grade gem-quality diamond is still a thing of value and beauty.
How rare is a diamond?
Diamonds are not particularly rare. In fact, compared to other gemstones, they’re the most common precious stone found. Generally, the cost per carat (or weight of a gemstone) is based upon a stone’s rarity; the rarer the stone, the more expensive.
What is the rarest gem?
Painite was first discovered by British gemologist Arthur Charles Davy Pain in 1951 and recognized as a new mineral in 1957. For many years only one specimen of the dark red crystal was in existence, housed at the British Museum in London, making it the world’s rarest gemstone.
What stone is closest to a diamond?
With its excellent brilliance and dispersion, it has a long history as a diamond simulant. In terms of appearance, zircon comes closer to diamond than any other mined gemstone. However, in terms of durability, it’s far more fragile. It will easily chip and abrade with wear.
How can you tell a raw diamond?
The only hardness test that will identify a diamond is scratching corundum. Corundum, which includes all rubys and sapphires, is 9 on the hardiness scale. If your suspected diamond crystal can scratch corundum, then there is a good chance that you found a diamond. But NO OTHER HARDNESS TEST will identify a diamond.
Can a jeweler tell if a diamond is real?
Jewelers and gemologists usually have a very fine tuned scale for measuring small differences in weight. The weight of a real diamond will be lower than fake stones like the Cubic Zirconia—but only special scales for weighing Carats will be able to detect these minute differences.
Where do real diamonds come from?
Diamonds come from the Earth.
A natural diamond’s creation began around 100 miles below the Earth’s surface. Each natural diamond is made of pure carbon, compressed by Earth’s pressure over time, and is the hardest substance on earth that exists naturally.
How much are real diamonds worth?
Calculating Diamond Price Per Carat

Are Diamonds Crystal?
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form of carbon, but diamond almost never converts to it.
