RAZOR-SHARP, glassy octos to 3 cm dominate the top of this specimen. They are extremely glassy, lustrous, and translucent in the outer layers, but the interiors are unusual in that they either enclose brown quartz matrix or are themselves colored differently than the outer 6-8 mm or so. This results in unusual dark cores, to these octos. As a whole, though, the piece is very dramatic and still shows mostly green, in person.
