Okorusu is renowned for its multi-hued, attractive Fluorites, and we are fortunate that a piece this good has become available. The crystals are sharp, a DEEP transparent purple/green, and multiply-phantomed. When backlit, you can see the colors change from green to blue throughout, and you can clearly see that the phantoms. The luster is very good, and the largest crystal is an impressive 3.2 cm on edge. It is one of the better pieces from here that I have seen for sale in awhile, and is representative of older material from the 1970s and early 1980s finds, as it last changed hands in 1994. Choice aesthetics.
