Polished Grey-Blue Tumbled Stone (Likely Labradorite or Moonstone)

The item is a small, polished, and irregularly shaped tumbled stone, held in the palm of a hand. Its primary colors range from a deep, somewhat translucent grey-blue to a lighter, almost milky white or pale blue, exhibiting a definite chatoyancy or adularescence, which is a milky, bluish luster or sheen, especially when light hits it at certain angles. This optical phenomenon suggests it could be a variety of feldspar such as labradorite or moonstone, or possibly even a high-quality chalcedony. The surface appears very smooth and well-polished, indicating it has undergone a tumbling process to achieve its rounded, organic form with no sharp edges or facets. The light reflections on its surface show distinct bright streaks, characteristic of the aforementioned optical effects, implying excellent craftsmanship in its polishing. There are no visible chips, cracks, or significant abrasions. The stone appears to be in very good condition, free from any discernible manufacturing marks or natural inclusions that would detract from its aesthetic appeal. Its small size, approximate to a fingertip, suggests it could be used for jewelry components, meditation stones, or part of a mineral collection. The craftsmanship is evident in the uniform polish and the successful enhancement of its natural optical properties.
