This striking 2.85 carat freeform rainbow garnet from Arlit, Niger, displays a vivid spectacle of color through its highly reflective, lightly polished euhedral crystal faces. The primary face radiates a strong metallic diffraction in golden, violet, and green hues, while two smaller adjacent faces add shimmering accents that catch and redirect light with a brilliant spectral flash. The geometry and polish on this piece enhance the natural lamellar structure of the andradite, which is responsible for the rare and highly coveted diffraction-based iridescence unique to rainbow garnets.

Sourced from the renowned Arlit locality in the Agadez Region of Niger—considered one of the world’s finest sources for iridescent garnet—this specimen exemplifies the optical phenomena that make these garnets so prized. The naturally formed faces maintain their crystallographic character while the polish reveals an internal world of spectral fire. The result is a dazzling gem ideal for a high-end ring or a centerpiece in a collector's case. This is a top-grade example from a locality celebrated for producing only a handful of such high-saturation, high-brilliance pieces.
