Daylight Fluorescent Hyalite Opal Specimen welo This piece is pictured underThis hyalite opal specimen not only will glow under an artificial UV lighting source, this particular source of hyalite opal will actually fluoresce in daylight, too! That is what makes this source(Zacatecas, Mexico) so unique. It looks best in diffused daylight, right outside of direct sunlight and it will have subtle green glow, while in indoor home lighting, much of this opal is almost colorless. The intensity of daylight fluorescence will vary
