This 16.4 carat freeform rainbow garnet cabochon from San Pedro Mountain, New Mexico, is a showstopper in every sense. With a commanding primary face measuring 19mm in length, this piece erupts in electric peacock coloration—a blazing combination of neon blue, vivid green, and flashes of deep indigo and golden teal. The lamellar diffraction is so intense and saturated that the stone appears almost illuminated from within, producing one of the brightest and most vibrant optical displays ever seen in garnet.

What makes this specimen truly extraordinary is its origin: it was cut from the same pocket as the renowned "Peacock Plume", widely regarded as one of the finest rainbow garnets ever discovered. Like its sibling, this stone possesses that rare, surreal intensity and spectral coherence that only occurs under ideal geological conditions.

The freeform cut honors the crystal's natural geometry while revealing an expansive, flat face that maximizes the dynamic iridescence. Subtle curves and angles around the edges allow the colors to ripple and shift with movement, creating a captivating play of light and color from every direction.

Measuring 19mm x 5.75mm x 14.5mm, this cabochon is as sculptural as it is gemmy—a museum-grade optical mineral specimen, or a once-in-a-lifetime centerpiece for visionary jewelry. A living flash of color from one of the planet’s most extraordinary mineral pockets.
