Daylight Fluorescent Hyalite Opal Madagascar It displays the same daylightThis 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.
