There’s hardly anything more beautiful and precious on Earth than a diamond formed of black coal. We are all mesmerized by its unmatched beauty, elegance, and history, yet we know so little about it. We would like to share with you the ten most important and useful information that’s worth knowing about it.
- DIAMOND IS THE HARDEST GEMSTONE THERE IS
Diamond forms of pure carbon atoms in an extremely rigid crystal structure, into one of the hardest naturally occurring materials on Earth. It has the highest score, 10, on Mohs’ hardness scale of minerals. It does not scratch or wears away and your diamond ring will forever shine bright if you take good care of it.
- DIAMOND IS THE SYMBOL OF ETERNAL BOND
Diamond originates from the Greek word “adamas’ meaning unconquerable. The first mentions about gifting a diamond go back all the way to the 15th century and it is still the symbol of eternal love ever since. In ancient Greece, diamonds were considered to be the teardrops of the gods falling on Earth.
- DIAMONDS ARE BROUGHT TO THE SURFACE BY VOLCANOES
Diamonds are created at least 150 km deep down in the crust of the Earth over billions of years at extremely high pressure and a 1000 degree Celsius. Volcanic eruptions brought the diamonds closer to the surface over the millions of years, from where they are mined today.
Interesting fact: it can also happen, very rarely, that a meteor hits the Earth and the high pressure and temperature make way for the precious gemstones to be formed.
- A DIAMOND’S WORTH DEPENDS ON ITS COLOUR TOO
Diamonds occur in many different colours in nature, such as yellow, brown, blue, green, purple, and black too. The whiter the diamond, the more it’s worth, although some very expensive, unique colours also exist, like blue or pink. The most precious diamonds are colourless, but most of them have a little yellowish tint. Colours are marked in many different ways, the most commonly used scale is the one with the letters of the alphabet, starting with D that marks the clearest, highest quality diamonds.
- CARAT REFERS TO THE WEIGHT OF THE DIAMOND
Diamonds are priced per ct (short for carat), which represents the weight of the stone. One carat (1 ct) equals 0,20 grams. Weighing is done in great punctuality to three decimal places and the third number can only be rounded up if it’s a 9. Certificates include the weight to two decimal places.
Interesting fact: extremely valuable coloured diamonds over 10 carat only surface maybe once a year in the whole world.
- DIAMOND FIRE
A diamond’s fire is the mesmerizing sparkle we all love about these precious gems. When the gemstone is exposed to light it breaks it down to different colours and reflects it back. Diamonds have an excellent refractive index, and with the right shaping, it will perfectly reflect the light back. To create the well-known round shape diamond, 57 facets are cut to the surface and so when the light enters the stone the facets break it to the colour spectrum and reflect it back to create the most amazing diamond fire. The round shape diamond is able to reflect back 100% of the light.
- VALUING DIAMONDS – THE 4C’S
Diamonds are assessed and certified based on four standards (4C), that highly influence their price: cut, carat weight, clarity, and colour.
- EVERY DIAMOND COMES WITH A CERTIFICATION
Apart from the 4C’s, trademark, date, and signature that every certification includes, further details can also be included in the certificate such as size, fluorescence, and a map of the interior or exterior flaws. The certificate guarantees the origin and quality of the diamond.
- DIAMONDS ARE NOT ALWAYS FLAWLESS
The clarity of a diamond is determined by the absence of flaws. During grading the diamond is viewed under a 10x microscope to check for inclusions (flaws) that can lower the quality, reduce the transparency, and effect the colour of the stone. A flawless diamond – without any internal or external flaws – is the rarest of rare.
- WAYS TO RECOGNIZE A REAL DIAMOND PROFESSIONALLY AND AT HOME
Diamond’s thermal conductivity is six times better than copper’s. This can be used both in determining the authenticity of a diamond and in nanotechnology.
X-ray technology helps to detect diamonds hiding inside rocks of volcanic origin as diamonds irradiated and activated by X-rays emit light in the optical spectrum.
Fog test: place the stone in front of your mouth and, like a mirror, fog it up with your breath. If the stone stays fogged for a few seconds, then it’s probably a fake. A real diamond won’t fog up easily.
Newspaper test: The newspaper test is most effectively used on loose diamonds, because of the refraction of light, you won’t be able to see clearly through it and make out the letters on the paper
