This 7.6 carat rainbow garnet cluster from Arlit, Niger is a standout example of sharp crystallography fused with intense optical phenomena. Lightly polished to enhance the natural form without compromising its integrity, this piece features unusually well-defined dodecahedral faces—each catching light in a different way, revealing metallic flashes of vivid rainbow diffraction. The spectral effect is visible on every face, with hues of electric gold, violet, cobalt, and magenta shimmering across the surface in shifting bands. Measuring 12mm x 10.3mm x 7.25mm, this is a high-grade miniature sculpture of geological symmetry and light, emblematic of why Arlit is considered the top locality for iridescent andradite garnet. Ideal for collectors who appreciate crystallography as much as optical wonder.
