This striking cluster of rainbow garnet crystals from Arlit, Niger, measures a substantial 23 × 18.4 × 15.2 mm and exhibits exceptionally sharp terminations uncommon in this locality’s typical specimens. Each crystal face gleams with intense lamellar diffraction, throwing off vivid metallic flashes of ruby-red, emerald-green, sapphire-blue, and sunset-orange. The arrangement of well-defined, intergrown crystals amplifies its overall brilliance, making it a standout example of Arlit’s rare spectral garnets. Ideal for mineral collectors seeking top-quality Nigerien material or as a dramatic display piece.
