This 4.43 carat freeform radiant-faceted rainbow garnet from San Pedro Mountain, New Mexico is a masterful blend of natural optical phenomena and precision artistry. Cut by Tyler Kahn, this high-quality stone features a complex and dynamic faceting design at its apex, carefully engineered to highlight the interplay between multiple diffraction planes within the garnet’s internal structure.

Measuring 11.2mm x 8.15mm x 4.9mm, the stone showcases bright, spectral iridescent faces, flashing vivid bands of gold, blue, violet, and green as it moves through the light. The customized freeform radiant cut maximizes both surface brilliance and internal fire, allowing the lamellar diffraction to come alive in a kaleidoscopic play of metallic color from every angle.

Rainbow garnets of this gem quality are rare enough, but precision faceted stones that amplify and harmonize the diffraction phenomena are truly exceptional. This piece bridges the worlds of fine jewelry and elite mineral collecting—a wearable spectrum, sculpted to reveal the hidden geometries of Earth’s optical wonders.
