Meionite Scapolite faceted ronelles have a vitreous luster, seem to have either a fluorescent or a luminescent quality but no testing has been performed to confirm, the gems are extremely brilliant with no visable internal characteristics, the body color is a lightly saturated slightly greyish brown hue showing a flash of yellow tone of undeniable beauty, and these gems are expertly crafted for a well made symmetrical rondelle.
