Feldspar 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 large, thick crystal in good condition, with a cleavage face on the back and minor edge chipping. The crystal has a good yellow coloration and is internally transparent. Weighs 25 grams.
