The Most Rare & Expensive Stone on Earth: Meet Calacatta Quartz If you’re fascinated by rare and luxurious materials, few stones captivate as uniquely as Calacatta Quartz. Often hailed as one of the most extraordinary crystals on Earth, Calacatta Quartz combines breathtaking beauty with unparalleled scarcity—making it truly the most rare and expensive stone in the world. ### What Is Calacatta Quartz? Calacatta Quartz is a type of high-quality, translucent petrified crystal belonging to the Quartz family. Unlike pure natural quartz, it features a signature delicate veining pattern—often described as crisscrossing, river-like streaks of white or pale gold against a milky or ivory background. This striking visual effect results from impurities and mineral inclusions during its formation deep within the Earth’s crust over millions of years.
