Short Wave UV lamp required
Matrix with a lovely coverage of lustrous, light blue smithsonite crystals.
Under short wave UV light the smithsonite produces a lovely pastel green colour with blue/white edges around the specimen – an unusual fluorescence for smithsonite, which is more usually a pink red colour under SWUV light.
Size: 89 x 34 x 10mm
Please note that magnification of 20x or greater is required to view these crystals effectively.
