Sirens Sing A Blues Gem
The “Siren of Serendip,” a 422.66-carat blue sapphire from Sri Lanka, is one of the world’s largest and finest, discovered nearly a century ago and now permanently displayed at the Houston Museum of Natural Science (HMNS) in Texas. Its journey from a mysterious unearthing to a stunning necklace designed by master jeweler Ingo Henn—featuring 913 diamonds and additional blue sapphires—unveiled in 2019—blends intrigue, craftsmanship, and a nod to its origins, with “Serendip” reflecting both its Ceylon roots and the fortunate chance of its acquisition. This gem, celebrated for its vivid hue and exceptional quality, stands as a testament to Sri Lanka’s rich geological heritage and human artistry, captivating visitors in the Lester & Sue Smith Gem Vault.
A Bolder Type of Opal
The 2,765-carat Australian Boulder Opal in the Cullen-Houston Collection is one of the most remarkable opals ever discovered. Mined in Queensland, Australia, this massive gemstone showcases a mesmerizing interplay of colors, with vibrant flashes of blue, green, and red embedded within its ironstone matrix. Unlike solid opals, boulder opals form naturally within ironstone, creating unique patterns and depth that make each specimen one-of-a-kind. This particular opal, weighing over half a kilogram, stands as a testament to nature’s artistry and the rarity of high-quality boulder opals. As a highlight of the Cullen-Houston Collection, it represents both geological wonder and the enduring allure of Australia’s opal fields.
Visiting the Cullen Hall of Gems and Minerals at the Houston Museum of Natural Science is an unforgettable experience, offering a dazzling display of some of the world’s most extraordinary gemstones. Whether you’re a gem enthusiast or just love seeing nature’s most beautiful creations up close, the collection’s vibrant colors, rare specimens, and fascinating stories make it a must-see attraction.
