Enigma Black Diamond sold at auction for $ 4.3 million
Sotheby’s sold the 555.55-carat Fancy Black Diamond at auction – probably from space – for an astronomical $ 4.28 million on Tuesday. The bids were closed at GBP 3.2 million, excluding the buyer’s premium, and the diamond was offered without a reserve
According to the Guinness Book of Records, Enigma is known to be the largest auction of cut diamonds in the world with 55 shares. It will weigh more than the Big Star of Africa (530.2 carats) and the Golden Jubilee (545.67 carats). The rare black carbonado diamond is thought to be of extraterrestrial origin because it contains small amounts of nitrogen and hydrogen and may be more than 2 billion years old. The size, shape and source of Enigma Diamonds make it groundbreaking and unique.
Traditionally, diamonds have been prized for their purity and lack of color. Black carbonados are not commonly used in jewelry and are often used in industrial drilling. But in recent years, many natural black diamonds, such as Black Orlov (67.5 carats), Amsterdam Diamond (33.74 carats) and now Enigma black diamonds, have become an expensive product.
The origins of the carbonado black diamond add to The Enigma’s attraction, which jewelers and geologists call an unsolved, interstellar mystery. While most diamonds are mined from igneous rocks formed deep in the earth, carbonados are found in sedimentary sediments near or on the earth’s surface. This suggests that black diamonds may have formed in space, and some believe that carbonados formed during a meteorite impact or supernova explosion.
Enigma Black Diamond at auction at Sotheby’s
Sotheby’s has announced that it will accept a cryptocurrency for The Enigma.
Enigma’s stunning cut and finish adds fuel to the final auction price. The original Enigma was purchased in the late 1990s and in its rough, newly excavated form would weigh more than 800 carats. Cutting to its current form took more than three years. According to Sotheby’s, Enigma, despite its shocking weight, is unique in that it has only 55 functions, but has a “high gloss level that is almost unimaginable.”
Kormind says that while most diamonds are cut into one of ten popular shapes, Enigma is similar on the one hand, another unique to the jewelry industry. Its shape is the designation of the palm symbol of the Middle East, Hamsa, the sign of protection and the instrument of diversion from the evil eye; according to Sotheby’s it also represents blessing, power and might.
While The Enigma’s final hammer award did not set a record, Kormind said, “What cannot be denied is that The Enigma is a diamond of incomparable brilliance.” He added: “Just imagine revealing to your visitors that you own the largest cut diamond in the world.”
Black diamonds have a high density of opaque mineral inclusions, especially graphite – a dark gray carbon form with a hexagonal structure, unlike diamond, which is a tetrahedral carbon form – and metal sulfide, said Peter Heaney, a. on black diamonds.
Sotheby’s describes Enigma as a carbonado diamond, the Portuguese name for black diamonds in the 19th century. Carbonado is a type of black diamond that is similar to polycrystalline, which means multiple crystals mixed in a single gemstone and is porous. Carbonado diamonds also contain many uranium phosphates, which produce “almost radiation” around the pores or holes on their surface. This property makes them more absorbing white light, so they are completely opaque and darker than other black diamonds.
“Carbonados are super hard and super tough,” because of their polycrystalline and porous properties. This makes them ideal for industrial use, as well as drills used in the oil industry to penetrate hard setting stones.
Due to its large size, Enigma is probably a real carbonate. After being looked at the enlarged images on a computer, it’s believed that Enigma with dimples (meaning it’s porous), which suggests carbonade, but it’s hard to say for sure, because diamond cuts do. It is also difficult to see from the pictures whether the diamond is really opaque.
All known carbonados were found in Brazil or the Central African Republic and, were dated about 3.8 billion years ago. At present, both countries belong to the same supercontinent known as Rodinia, and how and where diamonds originate is still unclear.
The auction house admitted that Enigma probably came from the effects of a meteorite.
It is possible that the carbonados were of extraterrestrial origin, as the auction house claimed. Researchers have found black diamonds created by meteorites in the past, but these diamonds are usually very small, so they are unlikely to be the source of real carbonados as large as Enigma.
Other space theories speculate that fully formed carbonates are already present in some asteroids that have crashed into Earth, or even that diamonds are formed by powerful stellar explosions called supernovae, but there is not enough evidence to support any of these ideas. Heaney said.
“I think the chances of the carbonado samples we studied and saw data coming from space are low,” said Richard Ketcham, a geologist at the University of Texas at Austin who also studies black diamonds. , said Live Science. The idea of space-based carbonados is “a minority point of view of those who study it,” he added.
However, it’s believed it is the most likely source of carbonados here on earth. However, the exact mechanism that these black diamonds form is not yet clear. Most diamonds are formed when high pressure in the Earth’s mantle or mantle breaks up organic carbon. However, the oldest carbonados probably dominate life on Earth – and thus organic carbon – which prevents them from forming in this way.
According to other reports, since Enigma was cut out, it’s also harder to know how it started. “The outer surfaces of carbonados are likely to have their origins, which are now likely to be lost,” It is hoped that anyone who buys an Enigma will place it in a public exhibition instead of keeping it in a private collection. Many large diamonds have not seen sunlight for decades.
