This exceptional 5.4 ct freeform rose-cut rainbow garnet crystal from San Pedro Mountain, New Mexico, is a rare example of top-tier material from one of the world’s only known sources of naturally iridescent andradite garnet. The stone features a sculpted array of rose-cut facets over a carefully preserved natural crystal form, with every face polished just deep enough to reveal its most vibrant diffraction layers. The resulting optical display is extraordinary—explosions of bright spectral color shift dynamically across the surface, with neon flashes of blue, magenta, gold, green, and violet that appear to move with light and angle.

Rainbow garnets from San Pedro are already rare, but pieces with this level of brilliance and color saturation are exceptionally uncommon. The locality produces a very limited quantity of diffraction-bearing garnet, most of which shows only partial iridescence or muted hues. Stones like this—where intense lamellar diffraction is present across the majority of the surface—represent the absolute best the deposit has to offer.

Meticulously cut to honor both the crystal’s natural symmetry and optical potential, this piece stands at the intersection of aesthetic mineralogy and lapidary artistry. It is a true collector’s gem—ideal for a world-class mineral display or a custom-designed talismanic jewel that captures the raw magic of the Earth.
