Laguna Agate with Druze Quartz Center (B)

  Laguna Agate, a translucent variety of chalcedony, is found only in the mountains of Ojo Laguna in Chihuahua, Mexico, and is prized for its rich color and precise banding. This specimen features a druze quartz center, well-defined concentric layers, and a subtle parallax effect where alternating opaque and transparent bands create shifting depth and shadow. Face polished to reveal its intricate patterning, this piece weighs 85 g and measures approximately 48 × 43 mm.
