Ethiopian opal rough pieces from Walo, Ethiopia, Africa. These pieces are opaque when dry but when wet they show gorgeous phantom iridescent colors.
Beautiful pieces to have in any mineral/crystal collection, gem collection or oddities collection.
Caution: Ethiopian opals are hydrophane — they absorb moisture. Keep them wet once they get wet, because when they dry their inner structure becomes weak and brittle and can crack. This mainly affects Ethiopian opals.
