Alexandrite from Brazil: one of the rarest of gems. This material is a mix of opaque rough natural genuine Alexandrite/Chrysoberyl. Some stones would cut into cabochons and are suitable for collectors and metaphysical uses. For those that have always wanted to collect or facet some genuine Alexandrite, this is your chance! Though this material does not have the complete red to green color change of the finest gem grade Alexandrite, it does come at a fraction of the cost.
