Colorado Yule Marble: Rare Stone, Epic Story
High in the Rockies, over 9,000 feet above sea level, is the only place on Earth where Colorado Yule Marble is found: Yule Creek Valley near Marble, Colorado.
Forged by fire, formed in purity.
Yule Marble was created by an intense geological process called contact metamorphism—a rare transformation that occurs when molten magma comes into direct contact with limestone, subjecting it to extreme heat, sometimes reaching 2,900°F. This rapid, localized heating causes the stone to recrystallize into marble with a dense, uniform structure and extraordinary purity—about 99.5% pure calcite.
By contrast, most commercial marble throughout the world, including well-known varieties from other states, Italy, India, Greece, and other countries forms through regional metamorphism. This slower, widespread process results from tectonic plates gradually compressing limestone over time, using moderate heat and intense pressure. While it produces high-quality marble, it lacks the exceptional clarity and fine crystalline structure found in Yule.
Because contact metamorphism is so localized, large, usable deposits of marble formed this way are exceptionally rare. The deposit in Colorado’s Yule Creek Valley is one of the few known examples in the world—and the only one of its kind in North America.
This rarity, paired with its iconic use in national landmarks like the Lincoln Memorial and the Tomb of the Unknown Soldier, makes Yule Marble not only geologically unique but also artistically and historically significant.
Colorado Yule Marble isn’t just stone—it’s history, geology, and art, carved by time and refined by fire.
