This extraordinary 6.63 ct asterized rainbow garnet cabochon from San Pedro Mountain, New Mexico, stands among the finest known examples of its kind. Cut to reveal a vivid, multidirectional star-like display of lamellar diffraction, this gem bursts with neon color—radiating brilliant flashes of blue, gold, green, and fiery copper that dance across the domed surface. The brightness and clarity of the optical effect elevate this piece to the very top tier of what has ever been recovered from this now-exhausted locality.

What makes this stone especially significant is the intensity and coherence of the star diffraction pattern—phenomena rarely this well-defined in San Pedro material. A single minor subsurface fracture is present, a common feature in this naturally stress-prone garnet, but it does little to distract from the overwhelming visual impact. This is not only a collector’s gem—it is a museum-grade specimen that captures the ephemeral beauty of a locality that is no longer producing.

For the advanced collector, curator, or talismanic jeweler, this is an irreplaceable offering—a rare geological artifact alive with spectral fire, from one of Earth’s most unique and elusive deposits.
