Diamonds have always fascinated us with their beauty and the mystery surrounding their<\/div>\n<\/div>\n
\n
origin. But how much do we really know about these extraordinary gems? <\/div>\n<\/div>\n<\/div>\n
\n
\n
There’s much more behind a diamond: we know them for luxury, price, and, unfortunately,<\/div>\n<\/div>\n
\n
also for the geopolitical controversies they can create.<\/div>\n
But that’s not all. At JW24, diamonds are our constant thought. <\/div>\n
We don’t trade natural stones, but lab-grown ones, identical in every way to real stones,<\/div>\n
but with greater attention to respecting the environment and workers.<\/div>\n
Don’t miss the 10 facts about diamonds (that you might not know) and discover all our jewelry<\/div>\n<\/div>\n<\/div>\n

1. Diamonds are born at incredible depths<\/h2>\n<\/div>\n<\/div>\n
\n
\n
Diamonds form about 150 kilometers below the Earth’s surface<\/strong>,<\/strong> where extreme temperatures and pressures transform carbon into precious crystals.<\/div>\n<\/div>\n
\n
This transformation takes millions of years, and diamonds are brought to the surface through<\/div>\n<\/div>\n
\n
violent volcanic eruptions that embed them within rocks called kimberlites.<\/div>\n<\/div>\n<\/div>\n
\n
\n
To extract these precious stones, as you can imagine, enormous technological,<\/div>\n<\/div>\n
\n
physical, and human efforts are required. Fortunately, today it is possible to replicate these geophysical conditions in <\/div>\n<\/div>\n
\n
laboratories, producing diamonds identical to natural ones. I <\/strong>Lab-grown diamonds <\/strong> <\/div>\n<\/div>\n
\n
not only offer the same quality and purity, but also represent a more<\/div>\n<\/div>\n
\n
responsible choice compared to mined diamonds, avoiding the consumption of natural resources and reducing<\/div>\n<\/div>\n
\n
environmental impact.<\/div>\n<\/div>\n<\/div>\n
\n
\n
<\/div>\n

2. Their origins are ancient<\/h2>\n<\/div>\n<\/div>\n
\n
\n
The oldest diamonds ever discovered are over 4 billion years old<\/strong>, making them among the<\/div>\n<\/div>\n
\n
longest-lasting materials on the planet. Prehistoric diamonds formed when the Earth was still <\/div>\n<\/div>\n
\n
young and going through phases of intense geological activity. Natural diamonds are therefore <\/div>\n<\/div>\n
\n
an extraordinary legacy of Earth’s past.<\/div>\n<\/div>\n<\/div>\n
\n
\n
This means that a natural diamond you buy today could be between<\/div>\n<\/div>\n
\n
1 and 3.5 billion years old<\/strong>.<\/div>\n<\/div>\n<\/div>\n
\n
\n

3. The color of diamonds is not just transparent<\/h3>\n<\/div>\n<\/div>\n<\/div>\n
\n
\n
\n
\n
\n
\n
\n
Although the classic colorless diamond is the most well-known, there are gems in vibrant hues<\/strong> <\/div>\n<\/div>\n
\n
such as pink, blue, green, and yellow. A diamond’s color is determined by the presence<\/strong> <\/div>\n<\/div>\n
\n
of chemical impurities or structural defects during the formation process.<\/div>\n<\/div>\n<\/div>\n
\n
\n
For example, blue diamonds contain traces of boron, while yellow diamonds owe their<\/div>\n<\/div>\n
\n
hue to the presence of nitrogen. Lab-grown diamonds offer the possibility to <\/div>\n<\/div>\n
\n
recreate these extraordinary hues through precise control of chemical elements<\/div>\n<\/div>\n
\n
during the growth process.<\/div>\n<\/div>\n<\/div>\n
\n
\n

4. They can withstand extreme heat<\/h3>\n<\/div>\n<\/div>\n
\n
\n
Diamond is known to be the hardest natural substance in the world, but it is also<\/div>\n<\/div>\n
\n
extremely resistant<\/strong> to heat. It can reach temperatures of about 1405\u00b0C before <\/div>\n<\/div>\n
\n
starting to burn, a characteristic that makes it ideal not only for jewelry but<\/div>\n<\/div>\n
\n
also for technological applications.<\/div>\n<\/div>\n<\/div>\n
\n
\n
For instance, diamonds are used in lasers, industrial cutting tools, and<\/div>\n<\/div>\n
\n
even as semiconductors in advanced electronic devices. After all, the “womb” that <\/div>\n<\/div>\n
\n
hosts them during their birth has temperatures of 1300\u00b0C and pressures between 45 and 60<\/strong> <\/div>\n<\/div>\n
\n
kilobars<\/strong>, or 45,000-60,000 times atmospheric pressure.<\/div>\n<\/div>\n<\/div>\n
\n
\n
Such conditions can only create indestructible stones.<\/div>\n<\/div>\n<\/div>\n
\n
\n

5. Some diamonds come from space<\/h3>\n<\/div>\n<\/div>\n
\n
\n
Meteorites can contain tiny diamonds formed during stellar explosions.<\/div>\n<\/div>\n<\/div>\n
\n
\n
Known as nanodiamonds<\/strong>, they develop under extreme pressures and temperatures created by<\/div>\n<\/div>\n
\n
cosmic events, such as supernovae or collisions between celestial bodies. Although not usable <\/div>\n<\/div>\n
\n
for jewelry, they represent a fascinating testimony to the processes that occur<\/div>\n<\/div>\n
\n
in space.<\/div>\n<\/div>\n<\/div>\n
\n
\n

6. The rarity of large diamonds<\/h3>\n<\/div>\n<\/div>\n
\n
\n
In some films, we see diamonds of considerable size that fit in the palm of a<\/div>\n<\/div>\n
\n
hand. But is it true? Is it possible for a diamond to be so large? <\/div>\n<\/div>\n<\/div>\n
\n
\n
Only one diamond in a thousand exceeds one carat after being cut and polished<\/strong>. The <\/div>\n<\/div>\n
\n
formation of large diamonds is a rare and complex process that requires extremely specific<\/div>\n<\/div>\n
\n
geological conditions.<\/div>\n<\/div>\n<\/div>\n
\n
\n
However, lab-grown diamond technology allows us to overcome these<\/div>\n<\/div>\n
\n
limitations, offering larger gems with the same purity and brilliance as<\/div>\n<\/div>\n
\n
natural ones.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
\n
\n
\n
\n
\n
\n
\n
This is possible thanks to advanced techniques such as the HPHT (High Pressure High<\/div>\n<\/div>\n
\n
Temperature) method or the CVD (Chemical Vapor Deposition) method, which allow control over<\/div>\n<\/div>\n
\n
every aspect of the diamond growth process.<\/div>\n<\/div>\n<\/div>\n
\n
\n
The result is a range of options spanning from small diamonds perfect for refined details<\/div>\n<\/div>\n
\n
to large carat gems ideal for unique and spectacular creations.<\/div>\n<\/div>\n<\/div>\n
\n
\n

7. Nanotechnologies reveal new perspectives on diamonds<\/h3>\n<\/div>\n<\/div>\n
\n
\n
In candle flames, diamond nanoparticles can be found. Although invisible to <\/div>\n<\/div>\n
\n
the naked eye, this phenomenon demonstrates how diamonds can form in unexpected<\/strong> <\/div>\n<\/div>\n
\n
contexts<\/strong>, expanding their scientific fascination.<\/div>\n<\/div>\n<\/div>\n
\n
\n
Nanotechnologies are exploring ways to use these particles in revolutionary<\/div>\n<\/div>\n
\n
applications, such as in medical treatments, industrial coatings, and even electronic<\/div>\n<\/div>\n
\n
devices. The ability to create diamonds at the nano level opens up new possibilities for advanced <\/div>\n<\/div>\n
\n
materials, offering opportunities that go well beyond traditional jewelry.<\/div>\n<\/div>\n<\/div>\n
\n
\n
<\/div>\n

8. Diamond rain on other planets<\/h3>\n<\/div>\n<\/div>\n
\n
\n
Uranus and Neptune, thanks to the presence of methane in their atmospheres, might<\/div>\n<\/div>\n
\n
experience diamond rain<\/strong> under the effect of extreme pressures. Laboratory experiments <\/div>\n<\/div>\n
\n
have shown that methane, subjected to temperature and pressure conditions similar to those<\/div>\n<\/div>\n
\n
present on these planets, separates into hydrogen and carbon, with<\/div>\n<\/div>\n
\n
the latter crystallizing into diamonds.<\/div>\n<\/div>\n<\/div>\n
\n
\n
Although this phenomenon cannot be observed directly, it offers a fascinating perspective<\/div>\n<\/div>\n
\n
on how widespread diamonds are in the universe, even in environments extremely<\/div>\n<\/div>\n
\n
different from ours.<\/div>\n<\/div>\n<\/div>\n
\n
\n
<\/div>\n

9. Not all diamonds are crystalline<\/h3>\n<\/div>\n<\/div>\n
\n
\n
Carbonados<\/strong>, also known as black diamonds, are a polycrystalline variety. They have a unique <\/div>\n<\/div>\n
\n
structure and high porosity, making them extraordinary both for their aesthetic aspect and for their<\/div>\n<\/div>\n
\n
industrial applications.<\/div>\n<\/div>\n<\/div>\n
\n
\n
Unlike transparent diamonds, carbonados are opaque and often used for cutting<\/div>\n<\/div>\n
\n
or drilling tools due to their exceptional resistance. Their origin is still <\/div>\n<\/div>\n
\n
a subject of scientific debate: some researchers believe they formed on Earth,<\/div>\n<\/div>\n
\n
while others hypothesize an extraterrestrial origin linked to meteorite impacts.<\/div>\n<\/div>\n<\/div>\n
\n
\n
<\/div>\n

10. Lab-grown diamonds: identical and sustainable<\/h3>\n<\/div>\n<\/div>\n
\n
\n
Lab-grown diamonds share the same chemical and physical composition as their<\/div>\n<\/div>\n
\n
natural counterparts. They are indistinguishable without specific tests<\/strong>, but their production is ethical<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
\n
\n
\n
\n
\n
\n
and environmentally friendly, offering a conscious choice for those seeking responsible luxury.<\/div>\n<\/div>\n<\/div>\n
\n
\n
Their growth requires significantly less energy consumption compared to<\/div>\n<\/div>\n
\n
natural diamond extraction, reducing the environmental and social impact associated with<\/div>\n<\/div>\n
\n
mines.<\/div>\n
Moreover, the ability to produce diamonds on demand allows for meeting the specific needs<\/pre>\n<\/div>\n<\/div>\n
\n
of designers and clients, ensuring a personalized and high-quality product.<\/div>\n
With lab-grown diamonds, it’s possible to combine science, sustainability, and beauty in a single extraordinary<\/div>\n<\/div>\n
\n
jewel.<\/div>\n
