The Antique Kazak Caucasian Blue 1900s Rug is a superb example of early 20th-century textile art, showcasing the bold geometric designs and robust construction characteristic of its nomadic heritage. Hand-knotted from hand-spun wool, this runner features a deep indigo ground that provides a striking contrast to saturated madder reds, teal, and ivory accents. The central design displays a series of interconnected, stepped polygons in an allover pattern, creating visual continuity across its long, narrow format. Natural dyes have matured over a century to produce a magnificent patina, making this authentic piece from the Caucasus region a compelling acquisition for collectors. With a 0.5-inch pile height, this wool rug combines historical significance with enduring quality.
