"Emeraldolite": A New Synthetic Emerald Overgrowth on Natural Beryl

This article describes a new manufactured gem material marketed under the trade name "Emeraldolite," which is an epitaxial growth of flux synthetic emerald on opaque white beryl. The material has a distinctive visual appearance, and is commonly used for jewelry in its "rough" form. The gemological properties of "Emeraldolite" are very similar to those normally shown by flux-grown synthetic emeralds.
