Where do they come from?
Natural diamonds are the result of a very long geological process. They are extracted in mines, by excavation of the ground, requiring deep and intense digging.
Mining and natural process
To crystallize, carbon must be subjected to extreme temperatures and pressures. In the Earth's mantle, the heat ranges from 1,000 to over 3,000 degrees Celsius, and the pressure is 137,000 times higher than that felt at the surface. The mantle is therefore the only place where there is enough heat and pressure to crystallize carbon and form natural diamonds.
Natural diamonds grow very slowly. It takes between 1 and 3 billion years for a diamond to reach a size large enough to be used in an engagement ring.
Extremely resistant, natural diamonds are the hardest minerals on the Mohs scale, capable of scratching the surface of steel. They survive volcanic movements and the shifting of tectonic plates, which transport them from the mantle to the Earth's crust, where they can be extracted by humans.
Rarity and value
Since natural diamonds form over a long period of time and undergo many different conditions during their formation, most natural diamonds have major flaws. Only about 30% of natural diamonds are considered to be of high quality and suitable for use in jewelry. This means that the number of natural diamonds available for engagement rings is limited and each one is considered a rarity.
The price of diamonds is stable and sustainable. An investment, a legacy to pass on…
A safe investment
The price of diamonds is less subject to fluctuations than gold, which makes them a more stable and regular investment. An object of beauty and luxury, diamonds are also a safe and coveted value on the investment market. Diamonds are known to be a safe bet, especially for a long-term investment, with growth of 2 to 3% per year. In recent years, demand has exploded and the trend is towards a decrease in the production of rough diamond mines, which is therefore pushing the price of diamonds up. That said, do not hope to make a fortune by investing in diamonds, because the buyback price of your stone will often be lower than the price at which you bought it. We therefore advise you to remain reasonable by investing no more than 10% of your savings in diamonds.
The advantage of the diamond is to be the smallest of the values of the least space and the most easily transportable. Add that the diamond is also easy to transmit. And what a pleasure to be able to wear or see worn on the finger the result of this investment and admire the beauty in all its facets. If you own a diamond or inherit a diamond, let yourself be assured by going through a diamond dealer or a jeweler specializing in precious stones that what you own is indeed a jewel and a valuable diamond.
The price of diamonds is set by a "Rapport" index in New York which establishes a weekly average of the prices charged on the Diamond Exchanges and thus determines the price of diamonds in dollars.
