400-Carat Emeralds & $25M Tiaras Inside Arab & Asian Royal Vaults

$25 million tiara to 400 carat emeralds, secrets of Arab and Asian royal jewels. We've all seen Margot Robbie dazzle the world in the legendary $8.8 million Taj Mahal necklace, a jewel so iconic it momentarily rewrote red carpet history. But tonight, we're stepping far beyond Hollywood loans and temporary glamour. Tonight, we're entering a far more secretive world. Multi-million dollar jewels owned, guarded, and quietly worn by Arab and Asian royal families. Pieces so valuable they could buy castles, private islands, and entire legacies. From colossal emeralds exceeding 400 carats, to diamond tiaras worth over $25 million. These are jewels that stayed with their royals, were custom acquired, and became permanent symbols of power, legacy, and unmatched wealth. Some resurfaced after decades. Others have only ever been worn once. And every single one tells a story the public was never supposed to know. Sheikha Moza, Bryony Raymond, New York, Emerald Cuff Her highness radiated timeless elegance at the Community Entrepreneurship Programme showcase, organised by the Ethics Initiative in partnership with the Arab Mentor Organisation, wearing an extraordinary high jewellery masterpiece. A colossal natural Colombian emerald bangle surpassing 400 carats, masterfully set in a lavish golden diamond cuff designed by Bryony Raymond, New York. This breathtaking bracelet, originally crafted in 1970, stands out as one of the most remarkable emerald-centric jewels ever seen in modern high jewellery circles. Its design showcases a single massive natural Colombian emerald centrepiece, known for its rich, intense green hue and exceptional clarity, framed by a halo of brilliant white diamonds and integrated into a sculptural 18-carat gold cuff. The expansive curved emerald sits prominently at the centre, while the surrounding pave and baguette-cut diamonds enhance its luminosity. This exceptional piece was once showcased at the prestigious Doha Jewellery and Watches Exhibition, one of the Middle East's foremost luxury showcases featuring rare gemstones and high, handmade jewellery from renowned houses and independent ateliers alike. Although the exact market value of such a custom and historical showpiece is rarely disclosed publicly, such jewels typically command multi-million dollar valuations at auction or private sale. Considering the extraordinary carat weight, artisan design and bespoke nature, industry experts estimate its worth to be $5 million. AMIRI GEMS – TOYOTE MOI RING We couldn't help but be captivated when this extraordinary Toyote Moi Ring by Amiri Gems was spotted on Sheikha Mossah bint Nasser during her visit to Qatar's Museum of Islamic Art for the launch of the Baghdad Eyes Delight exhibition. Custom designed exclusively for Sheikha Mossah, the ring features a striking pairing of two magnificent diamonds. On one side sits a 14-carat white pear-shaped diamond, celebrated for its crisp brilliance and elegant elongated silhouette. Opposite it, in deliberate contrast, is an exceptionally rare 18-carat fancy brownish-greenish-yellow diamond, a stone whose complex colour composition shifts subtly between warm honey, olive and golden tones depending on the light. The Toyote Moi setting allows each diamond to retain its individuality, while creating a harmonious dialogue between light and colour. The design is intentionally minimal yet architectural, ensuring nothing distracts from the sheer presence of the stones. Delicate, expertly engineered prongs elevate the diamonds just enough to maximise light return, while the band further accentuated with diamonds. What makes this ring particularly exceptional is the rarity of the natural brown undertone diamonds displaying green undertones combined with yellow modifiers are extraordinarily scarce, especially at such a significant 18-carat weight, making them far less frequently encountered and far more desirable to elite collectors. While Amiri Gems does not publicly disclose prices for bespoke creations of this magnitude, industry experts estimate that a ring combining a 14-carat white diamond with an 18-carat rare fancy-coloured diamond would command a value of $6 million, depending on colour grading, clarity and provenance. Cartier's Eternity Snake Diamond Necklace Among the most exquisite jewels from Sheikha Moser's legendary treasury stands Cartier's breathtaking Eternity Snake Diamond Necklace, a creation so rare that it exists almost outside conventional high jewellery classification. The original Eternity Snake Necklace was unveiled by Cartier to mark the Maison's 150-year anniversary and famously worn by Naomi Campbell. That version was crafted in platinum and embellished with what were then considered the two largest emeralds in the world, weighing an astonishing 205 and 206 carats, accompanied by 26 baroque pear-shaped emeralds, 3,957 diamonds and fine natural pearls. The creation reportedly required over 6,000 hours of meticulous handcraftsmanship, making it one of the most complex snake jewels ever produced by Cartier. For Sheikha Moser, the necklace is believed to have undergone an extraordinary transformation. The monumental emeralds were replaced with two imposing white diamonds, while the smaller emeralds and pearls were removed, resulting in a sleeker, more powerful diamond-centric composition. Sheikha Moser wore the necklace in 2010 in London, pairing it with a refined grey J. Mendel Kutcher gown, allowing the jewel's brilliance and sculptural presence to dominate without distraction, a masterclass in restrained power dressing. While Cartier has never publicly disclosed an official valuation, experts estimate that the original emerald version would exceed 25 to 30 million dollars today. The diamond-modified version, given the size and quality of the white diamonds, Cartier provenance and bespoke alteration for Sheikha Moser, is believed to carry a value of 15 million dollars. Princess Lala Hasna of Morocco Aga Khan Emerald HRH Princess Lala Hasna, President of the Safeguarding of the Cultural Heritage of Rabat, captivated all attention while wearing the Aga Khan Emerald, a legendary gem and one of the rarest fashion treasures on the planet. This extraordinary emerald tells the story of a jewel measuring an impressive 5 centimetres, a scale rarely seen in historic gemstones. The emerald appeared as a thrilling surprise, marking its first public appearance in more than 55 years. The brooch was originally commissioned in 1960 by Prince Aga Khan from Cartier-Paris as a wedding jewel for his bride, Nina Dyer, and stands as a masterwork of mid-century jewellery design. At its centre lies a magnificent 37-carat square-cut emerald, surrounded by 20 exquisite navette diamonds, with a combined weight of approximately 12.04 carats. In 1969, this exceptional jewel was auctioned at Christie's by Dyer to raise funds for animal causes. Over time it passed through the hands of both Van Cleef & Arpels and Harry Winston, famously known as the King of Diamonds. After spending decades away from public view, the brooch resurfaced at auction in 2024, where it began a remarkable new chapter. Now, the Aga Khan Emerald appears to have found its place within another royal collection, and did you know how much was paid for it? A record-setting 9 million dollars, a fitting price for a jewel often described as one of the rarest treasures on Earth. Sheikha Amna bint Muhammad Al-Thani Princess Marina Diamond Bow Brooch It came as a profound surprise when Sheikha Amna bint Muhammad Al-Thani appeared at the funeral of Queen Elizabeth II wearing the magnificent diamond bow brooch once owned by Princess Marina, Duchess of Kent, a jewel steeped in imperial history and quiet grandeur. The brooch is a masterful example of the classic bow motif, designed as a double-ribbon bow and centred by an elegant oval-shaped diamond of approximately 3.5 carats. It is lavishly accented with numerous pear-shaped and old mine-cut diamonds, together weighing an estimated 38.00 carats, while an additional array of smaller old mine and rose-cut diamonds contributes a remarkable 64.25 carats. The result is a jewel of extraordinary scale, depth and antique brilliance. This historic brooch originally belonged to Grand Duchess Elena Vladimirovna of Russia, Princess Marina's mother. Elena was the daughter of Grand Duke Vladimir Alexandrovich and Grand Duchess Maria Pavlovna, whose legendary jewellery collection was considered among the most spectacular in Imperial Europe, synonymous with wealth, taste and Romanov opulence. Following Princess Marina's death, this jewel of exceptional provenance was offered at auction. Its imperial lineage and impeccable craftsmanship sparked intense interest among collectors, and the brooch ultimately fetched nearly four times its estimate. Originally valued at $200,000 to $300,000, it achieved a final sale price of $842,500, underscoring its significance as both a historic artefact and a masterpiece of high jewellery. Queen Saleha of Brunei Multi-Coloured Diamond Tiara Queen Saleha of Brunei's coloured diamond tiara is widely regarded as one of the most massive diamond diadems ever worn by a queen consort, and remains unmatched in sheer material dominance within the South-East Asian royal sphere. This is a modern royal statement believed to have been acquired by Sultan Hassanal Bolkiah for Queen Saleha during a period when the Brunei royal family maintained close ties with graph diamonds, something clearly reflected in the tiara's bold contemporary design. Composed of extraordinarily large white and fancy yellow diamonds cut in modern, brilliant styles, the tiara features a dense, architectural wall of diamonds, construction with minimal visible metal, prioritising scale, rarity, and carat weight over symbolic motifs. Experts estimate the total diamond weight to be between 300 and 500 carats, with several individual stones likely exceeding 10 to 15 carats, including high-saturation yellow diamonds typical of graph craftsmanship. First worn publicly around 1992 during the Sultan of Brunei's Silver Jubilee celebrations, most notably at a banquet at Istana Nurul Iman and in an official portrait, the tiara is valued at approximately 20 to 25 million dollars, and for this, Queen Saleha loaned this extraordinary jewel only once, for her daughter's wedding, and never again cementing its status as a deeply personal royal treasure, and arguably the most valuable and imposing tiara in Malaysian royal history.
