Laguna Agate with Druze Quartz Center (A)

  Laguna Agate, a translucent variety of chalcedony from the mountains of Ojo Laguna in Chihuahua, Mexico, is prized for its exceptional color banding and fine detail. This specimen features defined, multicolored layers surrounding a small druze quartz center, with the face polished to reveal its intricate patterning. Laguna agates are among the most sought-after in the world, admired for their tight banding—sometimes exceeding a hundred layers per square inch—and the parallax effect that gives depth and movement to the stone. This piece weighs 50 g and measures approximately 52 × 35 mm.
