NWA 3206, IAB-sLH

This 176 gram disk-shaped iron is chemically a little odd and is structurally unique.  It has a great microscopic pattern, but there’s an overlying macroscopic structure that creates an odd scintillating visual effect.  Per the Meteoritical Bulletin write-up, it’s compositionally similar to one other iron — the 21.1 gram Lewis Cliff 86540.
