This 4.25 ct rainbow andradite garnet from San Pedro Mountain is a masterpiece of diffraction, polished to perfection and graded AAA for both quality and intensity. Measuring 10mm x 10mm x 5mm, it’s a balanced, symmetrical piece with a powerful presence.

Each of its four dominant faces ignites with neon electric blue flashes, the kind of lamellar diffraction that only shows up in the absolute top tier of San Pedro material. The flashes are bold and bright—like lightning caught in crystal—shifting with every slight movement of light.

This is a showpiece-level gem, ideal for a visionary jewelry setting or a collector looking for the very best. Stones with this level of iridescence, clarity, and color movement are exceptionally rare.
