An unusual Euclase with dense inclusions of dark Schorl needles, something I have never seen before. The Euclase crystal itself is well-formed, uncleaved on the edges and fairly lustrous. This crystal also has a faint blue "racing stripe" or color zone that is running along the "C" axis of the prism which adds extra eye appeal. This crystal comes with a custom made Acrylic base that displays this at the perfect angle. In person this is a rather dull or dark without good illumination. With a backlight however this really comes alive and the bright blue zone is pronounced. Really unusual for the specie and a very choice thumbnail.
