Felspar is a mineral not ususally known for fine collector gem crystals, but at this locality in Madagascar, amazing water clear crystals are sometimes found. This is a thick, gemmy crystal in good condition (I found 1 small chip). The crystal is terminated with four smooth, flat prism faces. The crystal has a good yellow coloration and is internally transparent - looks to me like facet quality for the entire crystal. Weighs 35.91 grams.
