Wondering why are Diamonds expensive?

Just like the story behind your future diamond purchase, there is a unique story behind the creation of each stone. Natural mined diamonds are seen as precious miracles from nature because of the incredible way they have come to be. Older than life on earth, diamonds are estimated to be anywhere from one billion to three billion years old.

Diamonds take years to form and require extreme temperatures, and incredibly intense pressure. That explains expensive diamonds. Let’s dig deeper into some of the surprising reasons why are diamonds expensive.

The gemstone quality diamonds are nearly 100 percent pure carbon and are the only gemstone mineral made from a single element. They are formed at depths estimated between 125-200 kilometers (or 90 and 120 miles) beneath the Earth’s surface. The pressure is around 50,000 times greater than the atmospheric pressure at the Earth’s surface, and the temperature range is approximately 900°C to 1300°C (or 1652–2372 degrees Fahrenheit). These incredible conditions all coming together to create such beauty certainly warrants natural mined diamonds to be considered unique, rare, and even priceless.

Most diamonds occur in kimberlite pipes in a type of potassic volcanic rock. Two of the most common methods to extract diamonds are open-pit mining and underground mining.

The right cut: Before a diamond enters the consumer market, it passes through a cutting manufacturer. India is one of the most important diamond-cutting centers in the world, along with Russia, Israel, and Belgium. India cuts approximately 92 percent of the diamonds mined worldwide and accounts for nearly 65 percent by value.

The final destination:A polished diamond must pass a final inspection before it can be used in jewellery. The diamond is boiled in a solution of hydrochloric and sulfuric acid to cleanse it of oil, diamond powder, and debris, and then is examined to ensure that it meets the manufacturer’s quality standards. Once a diamond passes inspection, it is ready for jewelry use.Only 30 percentof the diamonds mined worldwide pass through as gem-quality.

Jewellers classify the physical attributes of diamonds using the 4Cs of diamond quality–Colour, Cut, Clarity, and Carat Weight

Carat Weight: The carat is the standard unit of weight for diamonds and other gemstones. The modern metric carat, equal to 0.2 grams, weighs exactly the same in every corner of the world.

Clarity: Clarity refers to the presence or absence of inclusions in a diamond. The majority of natural inclusions are invisible to the naked eye, yet they affect the way light is reflected and refracted within the stone. Inclusions appear in different shapes, such as crystals, clouds, or feathers.

Colour: The colour grade ranges from “D,” indicating virtually colourless, to “Z,” representing the largest presence of colour. Keep in mind that the closer a diamond is to the colourless end of the scale, the more light it will reflect. Reflected light equals more brilliance.

Cut:Though difficult to analyze or quantify, the cut of any diamond has three attributes: brilliance (the total light reflected from a diamond), fire (the dispersion of light into the colours of the spectrum), and scintillation (the flashes of light, or sparkle, when a diamond is moved).
