This eye-catching 2.85 carat rainbow andradite garnet from San Pedro Mountain exhibits an unusually flat face with vibrant, spectral lamellar diffraction. Brilliant flashes of blue, green, and gold shift across the polished surface in strong lighting, reminiscent of a prismatic light show. The geometric profile and low dome give it a unique aesthetic appeal, with clean lines that make it ideal for setting or display. Measuring 9mm x 7mm x 3mm, this gem is a superb example of the phenomenon in a petite, high-saturation format.
