This 8.95 carat rainbow garnet cabochon from San Pedro Mountain is cut in a sculptural shield shape that thoughtfully follows the natural geometry of the original crystal. A bright, spectral face dominates the piece with radiant bands of blue, while golden-peach toned flares shimmer from adjoining facets, giving the stone a dynamic interplay of color and movement. The polish reveals the intricate lamellar diffraction responsible for the iridescence, while preserving the essence of the garnet’s crystalline origin. Measuring 11mm x 15.1mm x 5.3mm, this is a striking and gemmy example from one of the world’s rarest optical garnet localities—capturing the phenomenon in a bold, architectural form.
