Infanta Maria Francisca de Bragança, Duchess of Coimbra, has married lawyer Duarte de Sousa Araújo Martins in 2023 and wore Queen Amalie’s Diamond Tiara. The bridal gown, a spectacular princess dress, was made by Luzia do Nascimento.

As the second daughter of the pretender to the Portuguese throne, Infanta María Francisca was expected to shine with an ornate family tiara on her head.

The infanta has finally walked to the altar with a creation that dates back to 1887 and was made for Amelia de Orleans with 800 diamonds set in silver and gold, fringes,fleur-de-lis motifs and several rows of diamond necklaces. The previous year, Amelia had married the heir to the Portuguese throne, Prince Charles, Duke of Braganza, becoming the new Duchess of Braganza, so the Portuguese Royal Family ordered the house Leitão & Irmão, named Official Jewelers of the Portuguese crown for King Louis I, the making of a luxurious tiara. In fact, it was the King himself who chose his daughter-in-law’s design, which is why she baptized it “le diadème Dom Luis.”

Maria Francisca wore the same solitär diamond earrings that were worn by her mother on her wedding day. They were a gift from the Duchess of Braganza’s mother, Raquel Pinheiro de Castro Curvello.

Sapphire and Diamond Brooch with Laurel Wreath Border | Duchess of York | Royal Wedding Presents from Queen Mother | Diamond Jewelry of Queen Elizabeth, the Queen Mother

In 1923, Lady Elizabeth Bowes-Lyons, the future Duchess of York, received an array of splendid gifts for her wedding. Among these was a remarkable sapphire and diamond brooch.

This exquisite piece was bestowed upon her by her husband’s aunt, Princess Louise, the Princess Royal (daughter of King Edward VII and Queen Alexandra), and Princess Louise’s daughter, Maud.

Queen Mother’s Carved Rock and Diamond Art deco Brooch Pendant| England Great Britain| Royal Wedding Gift in 1923

A mystery is solved.

Long time, nothing was known about the history of Elizabeth the Queen Mothers, carved rock crystal art deco brooch.

The eagle-eyed Frank had sent me a note from the August 1923 about Queen mother’s style.

And an earlier press story was found, from the May, one month after the royal wedding.

In the splendid year of 1923, a momentous occasion unfolded as Lady Elizabeth Bowes-Lyons, the destined Duchess of York, was graced with an array of resplendent treasures to embellish her wedding. Among these treasures, a remarkable Art Deco Pendant Brooch shone with unparalleled brilliance.

During the enchanting month of May in that very year, the spotlight of the press was cast upon a distinctive trend inaugurated by the Duchess of York – a trend that would captivate the realm of fashion.

A pendant of exquisite square-shaped crystal emerged as the centrepiece, its delicate contours accentuated by an almost imperceptible rim of onyx adorned with diamonds. This captivating pendant, suspended by an ornate loop that echoed its elegance, hung gracefully from a black moiré ribbon interlaced with crystal beads, all united by a platinum chain of utmost sophistication.

Among the trove of gifts bestowed upon the royal bride, a novelty of striking originality emerged – a purse of singular design. Its circular form, enveloped in ebony moiré, boasted a circumference bejeweled [with probably useable with that brooch ),that sparkled like stars.

That pendant brooch could be used also as: onyx and carved crystal clasp, a masterpiece of artistry, secured this objet d’art, which was further graced by its attachment to an onyx slave bangle.

In a realm where precious gems symbolize significant occasions, the Duchess of York ingeniously transformed her pendant into a resplendent headpiece, a magnificent homage to the grandeur of her visit to Australia during the illustrious Royal Tour of 1927.

As time waltzed on and the pages of history turned, the radiant reign of Elizabeth the Queen Mother drew to a close, but her legacy endured.

The carved rock crystal brooch, once worn with regal grace, found a new wearer upon the graceful form of Camilla, Duchess of Cornwall. With remarkable frequency, this treasure adorned her on diverse royal occasions, etching its presence into the annals of history. It gleamed proudly on the grand stage of Queen Elizabeth II’s 60th reign jubilee, as well as during the dignified ceremonies of parliamentary openings, a silent testament to the enduring elegance that transcends generations.

Diamonds, the Rare Treasures from the Depths

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.

Kimberlites are volatile-rich, occasionally diamond-bearing magmas that have erupted explosively at Earth’s surface in the geologic past1,2,3. These enigmatic magmas, originating from depths exceeding 150 km in Earth’s mantle1, occur in stable cratons and in pulses broadly synchronous with supercontinent cyclicity4. Whether their mobilization is driven by mantle plumes5 or by mechanical weakening of cratonic lithosphere4,6 remains unclear. Here we show that most kimberlites spanning the past billion years erupted about 30 million years (Myr) after continental breakup, suggesting an association with rifting processes. Our dynamical and analytical models show that physically steep lithosphere–asthenosphere boundaries (LABs) formed during rifting generate convective instabilities in the asthenosphere that slowly migrate many hundreds to thousands of kilometres inboard of rift zones. These instabilities endure many tens of millions of years after continental breakup and destabilize the basal tens of kilometres of the cratonic lithosphere, or keel. Displaced keel is replaced by a hot, upwelling mixture of asthenosphere and recycled volatile-rich keel in the return flow, causing decompressional partial melting. Our calculations show that this process can generate small-volume, low-degree, volatile-rich melts, closely matching the characteristics expected of kimberlites1,2,3. Together, these results provide a quantitative and mechanistic link between kimberlite episodicity and supercontinent cycles through progressive disruption of cratonic keels.

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.
