Once formed over 150 kilometers deep within the Earth’s mantle, diamonds now glitter on many a ring finger. A recent study sheds light on how these precious gems made their way to the surface. Through geological clues and model simulations, researchers revealed how the breakup of tectonic plates led to volcanic eruptions that brought these „treasure-rich“ materials within our reach.
Diamonds are made of ordinary carbon, but what sets them apart from materials like coal is their purity and consistency. Naturally, their highly compact crystal structure can only form under immense pressure and heat in the Earth’s mantle, conditions found at depths over 150 kilometers. Over millions of years, diamonds were „baked“ in this extreme environment. The process of how they reached the Earth’s surface was roughly understood: diamond-bearing rocks melted due to geological processes, rose through fissures, and eventually surfaced during volcanic eruptions. The remains of these cooled volcanoes formed the deposits where raw diamonds are found today, typically embedded in a material known as kimberlite, named after the South African diamond-rich location, Kimberley. However, previous models couldn’t fully explain the origin of kimberlite melts deep within the Earth. It was evident that these processes were somehow linked to the restructuring of the Earth’s tectonic plates.
Unraveling the Mobilization Process
To investigate the geological processes leading to mobilization and kimberlite eruptions, the team led by Thomas Gernon from the University of Southampton delved into the matter. „The pattern of diamond eruptions is cyclic and follows the rhythm of supercontinents forming and breaking apart over hundreds of millions of years. However, until now, we didn’t know the process that suddenly brings diamonds to the Earth’s surface after resting 150 kilometers deep for millions or billions of years,“ says Gernon.
To gather new insights, the researchers analyzed the global correlation between the occurrence of kimberlites and the history of tectonic plate movements on Earth. They combined radiometric dating results with tectonic reconstructions, revealing that kimberlites formed over the past billion years typically erupted about 30 million years after the breakup of continental plates in the corresponding regions. This suggested an association with specific processes occurring at rift zones.
Hot Processes at Plate Boundaries
To shed light on the exact mechanisms, the team developed geological model simulations that provided a plausible picture of the processes. According to their explanation, a continental plate thins considerably over many millions of years before it breaks apart. This process, known as „rifting,“ causes the Earth’s surface to sink, eventually forming a rift valley. This is currently happening in East Africa, where the Rift Valley is forming. The model suggests that something similar occurs deep within the Earth: pieces of the underside of the plate sink into the mantle while hotter rock flows in from below to fill the void—similar to seawater on the surface. This incoming magma destabilizes the surrounding rock containing diamonds, turning the previously ductile material into a liquid that then rises upward. Eventually, through volcanic eruptions, it reaches the surface and solidifies into diamond-rich kimberlite.
Furthermore, the researchers can explain why volcanic eruptions with diamond-rich kimberlite can occur relatively far from the continental edges. These eruptions are also ultimately caused by plate breakup. Dynamic processes that extend far and wide occur during this process. „These flows along the underside of tectonic plates remove a considerable amount of rock, dozens of kilometers thick. This chain reaction ultimately reaches regions of the continents that are far from rift zones,“ explains co-author Sascha Brune from the German Research Centre for Geosciences (GFZ) in Potsdam.
Emeralds from the Sultan Abdul Hamid -Cartier-the Maharaja of Nawanagar -Princess Anastasia of Greece -Harry Winston to Mrs Heidi Horten
Muzo emeralds are found in the Muzo mines of Colombia.

The journey of the Sultan’s collection of muzo emeralds from its origins in the Ottoman Empire to its current place in the possession of Mrs. Heidi Horten has been a long and fascinating one. The emerald was initially part of a collection owned by Abdul Hamid II, the last sultan of the Ottoman Empire. When the sultan was forced to abdicate in 1909, his collection of gems was sold at auction in Paris, and his emeralds were purchased by Cartier.
Over the years, the emerald changed hands several times, eventually ending up in the possession of Harry Winston. In 1959, Winston purchased a collection of 17 emeralds from the Maharaja of Nawanagar, six of which were used to create a necklace that included the Sultan’s emerald.

The necklace, which also included pear-shaped and round diamonds, was valued at one and a half million dollars at the time of its creation. Although several potential buyers expressed interest, only one South American seriously negotiated for it, but he ultimately decided to invest his money elsewhere.

The necklace was eventually sold to a European connoisseur, who had it mounted in its current form.
Mr. Horten later purchased the necklace for his wife, who wore it until her death in 2022. Now, the necklace is set to be offered at auction at Christie’s in Geneva in May 2023.
The story of the Sultan’s emeralds is a testament to the enduring appeal of rare and beautiful gems. Despite changing hands many times over the years, the necklace has remained a coveted piece of jewelry, admired for its exquisite craftsmanship and timeless elegance.

Nevertheless, it is logical that, jewels given by British Royal Family or as « Princess of Wales » would be kept, according to tradition within the Royal family.
“During her lifetime, Diana will keep the jewelry and family heirlooms she was given as Princess of Wales, but, according to tradition, they will be passed down and kept within the royal family ».
