Mineralogically complex specimen containing transparent fivegite replacements of delhayelite (here the fivegite appears slightly colored due to transmission of underlying mineral colors), with coarse to fine nearly black to medium green aegirine, reddish to brownish eudialyte altering to cream-brown lovozerite, with greyish massive nepheline and white sodalite - some are more readily seen in the child image. S420-910 N7576N
