Inside the Mogok Ruby Mine: The 25-Carat Sunrise Ruby Worth $30 Million (Full Process)

On the evening of 12 May 2015, in a hushed Sotheby's auction room in Geneva, a single ring made from a 25.59-carat crimson crystal shattered every record in the ruby world. Step inside the Mogok Ruby Mine and witness the extraordinary story of the Sunrise Ruby, the celebrated 25.59-carat "pigeon blood" gemstone that on the evening of 12 May 2015 sold for a record $30.42 million at Sotheby's Magnificent Jewels and Noble Jewels sale in Geneva, becoming the most expensive ruby ever sold at auction and shattering the record for the highest price per carat ever paid for a ruby at $1.19 million. This cinematic documentary reveals how one crystal born deep within the marble-hosted deposits of the ancient Mogok Valley became the single most valuable colored gemstone ever sold, apart from diamonds, in the entire history of jewelry auctions. For 1,500 years, the celebrated Mogok Valley has produced the world's most coveted rubies, with historical records confirming gemstone mining in the region as early as the 6th century AD. Known worldwide as the "Valley of Rubies," Mogok is prized among gem connoisseurs for producing corundum crystals of unmatched "pigeon blood" red, a poetic term coined by local merchants who said seeing a true pigeon-blood ruby was "like seeing the face of God." The Sunrise Ruby, cushion-shaped and completely unheated, exhibits this legendary hue in its purest form—a saturated red with a subtle blue undertone produced by the ideal balance of chromium and trace iron within the crystal lattice of corundum, the aluminum oxide mineral graded at 9 on the Mohs hardness scale, second only to diamond. This full-process documentary walks through every stage of the extraordinary journey—the geological formation of ruby crystals within metamorphic marble deposits shaped by the collision of the Indian and Eurasian tectonic plates, the traditional Mogok mining methods refined across centuries, the meticulous cushion cutting and polishing, the SSEF Swiss Foundation and Gübelin Gem Lab certifications verifying its origin and unheated condition, the celebrated Cartier platinum ring setting flanked by two shield-shaped diamonds weighing 2.47 and 2.70 carats, and the poetic naming of the gem after "The Sunrise Ruby," a 13th-century poem by the Persian Sufi poet Rumi. You'll witness the historic auction itself as it unfolded—the final lot 502 of the evening, the model in a black dress approaching the podium wearing the ring, the bidding beginning at 11 million Swiss francs, the seven-minute battle between two anonymous telephone collectors, the final hammer at 28.25 million Swiss francs, and the celebrated David Bennett of Sotheby's, then chairman of the jewelry division, declaring after forty years in the trade that he had never seen another ruby of this exceptional size and outstanding color. The Swiss Gemmological Institute described the gem as "a unique treasure of nature," while Gübelin concluded that a natural ruby of this size and quality was "extremely rare." Blending gemology, geology, and the legacy of one of the oldest gemstone traditions on Earth, this documentary explains how the Sunrise Ruby became the ultimate benchmark for the pigeon blood ruby market—defined by its 25.59-carat weight, its Mogok origin, its untreated natural clarity, its Cartier provenance, its Rumi-inspired name, and its historic $1.19 million-per-carat record that stood as the highest ever paid for a ruby at auction.
