This 3.8 ct freeform polished andradite is a radiant example of San Pedro Mountain’s most sought-after treasures. It displays brilliant lamellar diffraction, with dominant hues of cool blue and vivid green shifting across its surface like refracted light through water.

Measuring 11mm x 8mm x 3.5mm, this piece is sculpted to emphasize its natural optical play—revealing shimmering bands of color that dance as the angle changes. The hand-polished contours follow the flow of the crystal’s structure, enhancing its depth and movement.

This stone is a standout from the only locality in North America known for producing this unique iridescence in andradite. A mesmerizing specimen for high-end design or a serious gem collection—there’s nothing else quite like it.
