Ils ont découvert un diamant absolument massif—2 492 carats, en faisant le deuxième plus grand jamais trouvé ! 💎 La société minière canadienne Lucara Diamond Corp. a fait l'annonce en août 2024, et tout cela s'est passé dans la mine de Karowe au Botswana. Fait amusant, c'est le même endroit où le précédent deuxième diamant, le Lesedi La Rona de 1 109 carats, a été trouvé en 2015. Celui-là a été vendu pour la somme stupéfiante de 53 millions de dollars seulement deux ans plus tard ! Maintenant, tout le monde se demande combien vaudra ce nouveau géant. Une chose est sûre—quelqu'un s'apprête à devenir très riche !

00:00It is dark and hot, and it is difficult to breathe deeply underground in the mine of Karov, in the heart of Botswana.
00:08Your work day has started several hours ago, and yet the stone you are holding in your hands does not seem promising.
00:15On the other hand, there is a slim chance that it is the biggest diamond you have ever found.
00:21You decide to inform your Canadian bosses of the Ukara Diamond Corp, and bingo!
00:27The stone you have found turns out to be a stunning 2492 carat diamond, the second largest ever discovered.
00:37However, the average size of the ring rings is 1.7 carat.
00:42This means that this single diamond could be enough to provide rings to more than 1,465 married women.
00:48You can compare the size of this precious stone to that of a fist, and the weight of this priceless gem exceeds 400 grams.
00:57Its value has not yet been determined, but why not make some assumptions?
01:01Thus, another diamond of the same mine, which bears the name of Constellation, was sold for 63 million dollars in 2016.
01:10And it was only 813 carats, less than a third of the size of this new diamond.
01:17The only other discovered diamond that is larger is the famous Kulinan diamond.
01:22It was found in South Africa in 1905, and weighed 3106 carats.
01:28Now, calculate how many ring rings we could draw and write the number in the comments.
01:35Unfortunately, it was then cut into several smaller diamonds, and some of these fragments are now part of the British crown.
01:44Interesting fact, there was once an even larger stone that looked like a diamond.
01:49A black diamond called Carbonado.
01:52It was discovered on the surface of the ground in Brazil at the end of the 1800s.
01:56And the coolest thing is that it could come from a meteorite.
02:00The Carbonado Sergio, which is the name of the discovered stone, was divided into small pieces.
02:05They wanted to make industrial drilling wrenches out of it, because it is one of the most resistant materials on Earth.
02:11This new diamond was actually found using a cutting-edge technology.
02:15The company used a X-ray device called Megadiamond Recovery X-ray Transmission to detect the stone.
02:23It is not the first record diamond that Lucara found in the Karowe mine.
02:28In 2019, they discovered the Sewelo diamond, which weighed 1758 carats.
02:35At the time, it was the second largest diamond in the world.
02:39The luxury brand Louis Vuitton then bought the stone for an undisclosed amount.
02:45And before that, in 2015, they found the diamond Lesedilharona in the same mine.
02:52It weighed 1109 carats and brought 53 million dollars to the company in 2017.
03:00Diamonds are not the only surprising thing that can be found in the ground.
03:04The deeper you dig, the more likely you are to discover rare objects, such as an old lipstick, for example.
03:12It would be the oldest lipstick in the world.
03:15It would be about 5,000 years old.
03:17This deep red lipstick was found in a stone vial in southern Iran.
03:23The vial was discovered in 2001, but it took time for researchers to understand what it was.
03:29The reason is that it is not a modern tube lipstick.
03:33People probably applied it with a brush.
03:37Researchers are delighted, because this discovery could give us a glimpse of what women of the Bronze Age were doing to stand out.
03:44In elite societies, they probably applied this lipstick for a glamorous effect and displayed their high social status.
03:53Here is now the history of the vial.
03:55It comes from a cemetery of the 3rd millennium BC and is linked to the powerful Mesopotamian civilization.
04:02This civilization was very important at the time.
04:06The cemetery was discovered after a flood and, unfortunately, many objects were stolen.
04:12But fortunately, the authorities managed to recover this unique piece.
04:16The vial attracted the attention of scientists because it was different from the other objects they had found.
04:22Normally, they found gray and compact substances in similar containers.
04:27But when they opened this one, a fine powder spread.
04:32It was dark gray-purple, which they had never seen before.
04:37When the researchers analyzed the powder, they discovered that it was composed of hematite, which gave it this intense dark red color.
04:46It also contained other ingredients, such as vegetable oils and waxes, which made it very similar to what is found in a modern lipstick.
04:54Apparently, at the Bronze Age, makeup was a sign of luxury and high social status in this region.
05:01It was a sign of wealth and power, especially in elite circles.
05:06Moreover, researchers cannot say with certainty that it is the oldest lipstick in the world.
05:12Who knows, something older could appear one day.
05:17What if we went to Bulgaria right away to do some digging?
05:21Ah, wait!
05:23No need to take a shovel and get your hands dirty.
05:26An incredible discovery is already waiting for you.
05:29There, they found a large marble statue.
05:32It measures almost two meters high, which could represent Hermes, a Greek deity.
05:37But the craziest thing is that Eleatta was buried in an ancient well for about 2,000 years.
05:43The statue is in very good condition, especially the head, which is super well preserved.
05:48There are some cracks at the level of the hands.
05:51But overall, it is in incredible condition, according to the scientific director of the excavations.
05:57Here's how they found the statue.
05:59The team was doing routine searches in the southwest of Bulgaria, near the Greek border.
06:05This region used to be part of the old city of Heraclea Sintica, which dates back to the 4th century BC.
06:12While digging, the researchers came across the marble foot of the statue.
06:17From there, they carefully revealed the rest of the statue.
06:21It was a real surprise for them, because they did not expect to find something of this kind.
06:27At the moment, the team is trying to remove the statue from the wells without damaging it.
06:31It is very heavy.
06:33So they use a crane to lift it, and then they will transport it to the Petrek History Museum.
06:39Once restored, they plan to exhibit it.
06:42The experts are very enthusiastic.
06:45This discovery could teach us a lot about the culture of Heraclea Sintica, which is not a very well-known ancient site.
06:52Now, if you dream of making discoveries like this one, but you do not have a diploma, do not be discouraged.
06:59Even an amateur can make a scientific discovery.
07:02For example, you could find a Roman dodecahedron.
07:05It is a strange and mysterious 12-sided metal object, the size of a pamplum.
07:10And no one really knows what it was used for.
07:13Historians have been digging their heads about it for centuries.
07:18This dodecahedron was discovered last summer in the field of a farmer near Norton Disney, about 56 km southeast of Sheffield.
07:27A group of volunteers had already found coins and Roman brooches in the region, and therefore knew that the field could hold other treasures.
07:36A geophysical study had revealed underground areas where the terrestrial magnetic field was disturbed, which indicated that something could be hidden.
07:45The team began to dig trenches during a two-week search.
07:49The penultimate day, in trench 4, someone spotted the dodecahedron.
07:54Richard Parker, the group's secretary, was not far away, busy making tea when he heard a cry.
08:00They were all in shock because they had not found much metal, and then, boom, this impressive object appeared.
08:09What is even cooler with this dodecahedron is that it is complete, which is rare.
08:15Most of those we had discovered were broken or incomplete.
08:19In addition, it is larger than the others.
08:22Roman dodecahedrons can be as small as a golf ball, but this one looks more like a pamplum.
08:28Today, it is exhibited in a local museum.
08:31So far, more than 100 dodecahedrons have been discovered in northwestern Europe, mainly in ancient Roman territories, such as the Gallo-Roman regions.
08:40They date from a period between the 1st and 3rd centuries AD.
08:45Each of them is made up of a hollow metal shell, usually in bronze.
08:51It has 12 faces with holes of different sizes on each face.
08:56Around the holes, concentric rings are engraved in the metal, and at each angle where the faces meet is a small name.
09:04They have no inscription, and are not mentioned anywhere in Roman texts.
09:08This is why no one knows what these two dodecahedrons were used for.
09:12There are many theories.
09:14They could be toys, dice, masu heads, or even measuring tools for distances in Roman artillery.
09:21Some even think that they were used to knit gloves, or even to calculate dates using stars.
09:27But most of these ideas are not really founded.
