A gemologist can confirm identification using refractive index testing.
Can I use Alexandrite instead of Moonstone as a birthstone?
Yes, both Alexandrite and Moonstone are recognized birthstones for June. Alexandrite is the modern June birthstone and Moonstone is the alternative June birthstone, so either is an appropriate choice for that month.
