Top 10 Rarest Gemstone Jewels of Modern Royals You Will Ever See!

Top 10 rarest gemstones of modern royals. From the shimmering tanazites of Princess Catherine, to the fiery paribus of Bhutan's Queen Jetsun, the royal world has never stopped dazzling us with its love for rare and extraordinary gemstones. Each piece tells a story of love, legacy, and timeless beauty. Tonight we explore the modern royal's most unforgettable treasures, from the shimmering moonstones of Meghan Markle, to Queen Maxima's magical gems, and from Queen Elizabeth II's mysterious blue pearl, to Princess Grace's legendary Cartier Topaz brooch. These are the jewels that define a new era of royal elegance, rare, personal, and utterly breathtaking. Princess Catherine Tanazite's Suite There's no second thought that the princess has a deep fondness for blue gemstones, just like her late mother-in-law Princess Diana. Over the years, she has continued Diana's legacy by debuting stunning sapphire and blue-toned jewels that beautifully complement her iconic engagement ring, the 12-carat Ceylon Sapphire. Among her most remarkable additions is a breathtaking Tanzanite Suite, a modern royal treasure in every sense. Not only is Tanzanite one of the world's most recently discovered gemstones, but it is also mined in only one location, making it one of the rarest and most valuable stones on Earth. Drawn to its unique blue-violet luminosity, the princess collaborated with G. Collins & Sons, a family-run jeweler holding a royal warrant from Her Majesty the Queen, to create a bespoke Tanzanite set in 2015. The suite features pear-shaped, faceted Tanzanite earrings encircled by delicate white diamonds and a matching pendant showcasing an inverted pear-shaped Tanzanite surrounded by 20 brilliant-cut diamonds, a detail that adds exceptional sparkle and depth. She first wore the set at a service honouring British troops who served in Afghanistan, later donning it again for a private dinner with the Obamas at Kensington Palace in 2016, where the vivid blue tones perfectly echoed her sapphire engagement ring. In 2019, she once again graced the public eye with this royal blue ensemble during the Order of the Garter service, wearing what experts call one of the rarest gemstone suites, estimated at £30,000. QUEEN MAXIMA'S MOONSTONE AND BLUE GEMSUITE There's no denying that Queen Maxima's jewellery collection is one of the most adventurous in all of Europe's royal vaults, a dazzling spectrum of rare and exceptional gemstones. From her peridot and pearl earrings to that bold emerald ring and the fiery opal suite that has become one of her signatures, the Queen's jewels are a constant celebration of colour and individuality. Among her most captivating pieces is a unique suite featuring moonstones, tanzanites and iolites, a gift from King Willem-Alexander to commemorate their accession to the Dutch throne in 2013. The modern design, accented with pavé-set diamonds and luminous milky moonstones, carries a serene yet playful charm. Scattered among the stones are flashes of blue from tanzanite and iolite, creating a magical light play effect that perfectly suits Maxima's vibrant personality. The Queen debuted this mesmerising ensemble at the Circus Theatre in The Hague during the celebrations for the 200th anniversary of the Kingdom of the Netherlands in 2013. Since then, it has made rare but memorable reappearances, paired with a flowing white silk gown for the jubilee concert of Koninklijke Sofiers Verenigingen, when the royal couple hosted a luncheon for the Emir of Qatar and Sheikha Jawahar in The Hague. This suite is a combination of some rare gemstones, making it an unforgettable one. Sophie, Duchess of Edinburgh Jade Pendant The Queen's favourite daughter-in-law, the Countess of Wessex, possesses one of the most distinctive art deco jewels in the royal collection, a spectacular carved jade pendant encircled by diamonds and suspended from a fine chain. Of unknown provenance, this exquisite piece is believed to be antique in style, and was acquired by Sophie in the early 2000s. Jewellery expert Alexandra Michel described it as a beautiful rich green, intricately carved jade pendant, enclosed in a fine ring of diamonds, possibly art deco, weighing approximately 50 carats. Valued at around £80,000, the pendant first made its public debut in 2014, at a gala fundraising dinner for the Newport Minster Renewal Appeal, held at the Royal Yacht Squadron in Cowes. On that evening, the pendant was the centre of attention. The only other time she was seen wearing the piece was in 2017, at the first day of Royal Ascot, where she joined the Queen, the Prince and Princess of Wales, and other senior royals. Did you know the Duchess has an aquamarine ring just like Diana? I guess not. Just as Princess Diana had an enduring love for deep blue sapphires, Duchess Sophie appears equally captivated by the lighter shades of blue, particularly aquamarine. In 2013, she commissioned G. Collins and Sons, the same royal jewellers, to create a bespoke 20-carat aquamarine ring. The cushion-cut gemstone, set in handmade platinum, is valued at approximately £80,000. The Countess first wore the aquamarine ring at Royal Ascot 2008, and brought it back into the spotlight a decade later, at Royal Ascot 2018, where it momentarily sparked confusion. Many mistook it for Meghan Markle's inherited aquamarine from Princess Diana. Yet, Sophie's piece remains distinctly her own. Countess Dana's Citrine Earrings On April 30th, Queen Mary of Denmark arrived at Frederiksborg Slot in Hillerud to open a special exhibition dedicated to Countess Dana, the morganatic third wife of King Frederick VII. For the occasion, the Queen chose a jewel steeped in Danish royal history and romance, a pair of 165-year-old earrings once belonging to Countess Dana. Born Louise Rasmussen, she began her life as a ballet dancer and defied convention by marrying Crown Prince Frederick in 1850 despite public opposition. As she could not become Queen, she was instead granted the title Countess of Dana, and went on to build her own exquisite private jewellery collection. To pay tribute to this extraordinary woman, Queen Mary chose to wear a pair of exquisite gold earrings crafted in yellow gold, featuring a delicate nature-inspired design adorned with intricate leaf and floral motifs. At the heart of each earring rests a large oval-cut citrine, radiating a warm golden hue that captures the light beautifully. Surrounding the central stone are small round amethysts in deep violet tones, offering a striking contrast to the citrine's glow. At the top of each earring sits a single natural pearl, delicately set like a tiny flower bud, adding a soft and elegant finishing touch to this historic and romantic design. The earrings form part of a larger demi-perue commissioned by King Frederick VII for Louise, and crafted by Danish court jeweller Julius Didrichsen around 1860. Queen Mary also recently wore the same citrine earrings during her state visit to Finland earlier this year, once again bringing to light one of Denmark's most romantic and controversial royal treasures. Queen Elizabeth, Aotearoa's Pearl and Pacific Star Brooch. One of the least known yet most fascinating jewels in Queen Elizabeth II's collection is a brooch set with an exceptionally rare blue pearl, neither white nor black, but shimmering with iridescent hues unlike anything else in royal circles. The remarkable piece was a gift from New Zealand Prime Minister John Key during his visit to Balmoral Castle in September 2013. The brooch was created around a unique blue pearl sourced from Aeris Blue Pearls, a Christchurch-based company known for cultivating these extraordinary gems. Its founder, Roger Beattie, who has been farming blue pearls in Aotearoa since the mid-1990s, revealed that upon learning the jewel was destined for the Queen, nothing but the best would do. He personally sent five pearls from his private collection, from which John Key selected the finest one. Now known as Aotearoa's Pearl, the gem displays a mesmerising mix of green, gold, pink, blue and purple tones. The brooch's design combines mixed metal settings with marquise-cut diamonds, enhancing the pearl's depth and luminosity. The Queen first wore this rare treasure in 2014 for the opening of the newly refurbished reading station, showcasing one of the most unusual and captivating pearls ever to grace the Royal Jewel collection. Princess Grace had a known love for turquoise, a passion that led her to commission Cartier to create a stunning turquoise suite, complete with earrings and a magnificent brooch that still captivates jewellery lovers today. The brooch features a large rectangular topaz of warm golden-amber hue at its centre, its cut sides gleaming within a border of turquoise cabochon set in yellow gold. The contrast between the fiery depth of the topaz and the serene coolness of the turquoise is breathtaking. Each turquoise bead is delicately framed by diamond accents, adding a glaze of brilliance and light. The overall design, with its octagonal topaz, double rows of turquoise and scattered diamonds, embodies Cartier's mastery of colour and texture. Monaco itself seemed to turn turquoise when Princess Grace first debuted the suite, wearing it for the 1967 Palace Reception and again during the 1980 National Day celebrations. The brooch also became immortalised in one of her most iconic 1960s photo shoots, a portrait that captured both her elegance and her love for vivid gemstones. For decades, the whereabouts of the brooch remained a mystery. It was never seen on Princess Caroline or any other royal lady. But recently, it resurfaced in the exhibition Grace of Monaco, Princess and Dior, held in the Prince's Palace State Apartments. On display until September 14th, 2025, the exhibit unveils the icon her sunglasses, gloves, the iconic Hermès Kelly bag, and among them, this glittering turquoise and citrine Cartier masterpiece. The jewels of the Queen of Bhutan remain some of the most discreet and confidential in the world, much like those of the Japanese imperial family. Yet, among her closely guarded collection, one designer has captured her admiration, Anna Hu, a celebrated jewellery artist known for crafting masterpieces with some of the rarest and most valuable gemstones on earth. One of her most remarkable creations for the Queen is the beloved poppy earrings, designed specially to mark Her Majesty's honeymoon. Inspired by Bhutan's national flower, the delicate blue poppy, the earrings embody harmony, peace, and the spiritual pursuit of happiness. Crafted in 18-carat white gold, the design features a fiery ruby at its centre, encircled by sapphires, pariba tourmalines, and diamonds. The petals shimmer in hues of blue and violet, while the radiant sky blue pariba tourmaline evokes the tranquillity of the Himalayas. Her Majesty debuted the beloved poppy earrings during her visit to Japan, where she met Empress Michiko, making a quietly elegant statement that united Bhutanese symbolism and global craftsmanship. Another of her most admired pieces, and a personal favourite among royal watchers, is a pair of amethyst and hand-crafted royal jade earrings by S. Manifand, pieces she wore this year during traditional Bhutanese ceremonies and a local cultural exhibition. With their rich purple and serene green tones, they perfectly capture the Queen's signature blend of modern refinement and deep cultural pride, jewels that, like the Queen herself, remain wrapped in mystery and grace. Meghan Markle – Queen Ring Just recently, Meghan Markle, the Duchess of Sussex, debuted a dazzling new ring, believed to be a birthday gift from Prince Harry, and it has already captured global attention. The piece, known as the Queenwater Drop Moonstone Ring, is crafted in 14-carat gold and features a pear-shaped moonstone surrounded by a halo of white diamonds, creating a luminous, ethereal effect. According to the jeweller, the moonstone is said to bring good fortune and success in love and business, a fitting symbol for the Duchess' life journey. It's also no coincidence that the ring's design is reminiscent of the late Princess Diana's iconic sapphire engagement ring, which was encircled with white diamonds to create a halo effect. While Diana's ring, centred around a royal blue sapphire symbolising loyalty and grace, Meghan's moonstone, long associated with the Roman goddess Diana, adds a sweet tribute to her mother-in-law.
