Polished River Kobble Appraisal

Polished River Kobble with Quartz Veining

This is a naturally occurring water-worn river stone or cobble, measuring approximately 2.5 to 3 inches in length as compared to the human hand holding it. The stone exhibits a smooth, rounded surface indicating long-term fluvial erosion or glacial transport. The primary composition appears to be a fine-grained sedimentary or metamorphic host rock, characterized by a variegated color palette of olive green, tan, and dark charcoal grey. A prominent, thick band of milky white quartz Runs vertically through the specimen, indicating a geological history of hydrothermal mineral deposition within the parent rock. The surface shows some natural pitting and indentation particularly along the interface of the quartz vein and the host material. The condition is entirely natural with no signs of artificial polishing or human craftsmanship; it possesses a natural matte luster. There are no maker's marks or signatures, though the stone features a distinctive, almost heart-like silhouette in its rounded form. Small dark inclusions are visible throughout the greenish-tan segments, highlighting the complex mineralogy of the piece. Its age is geological, likely spanning millions of years, and it serves as an excellent example of natural physical weathering processes.
