At least 10 round Gyrolite nodules rest on the concave surface of this hand specinen. All but two of these nodules are intergrown into clusters, and they range in diameter from 0.1" (3 mm) to 0.6" (1.5 cm). Two of the clusters which rest on the edge of the surface are damaged and not quite complete, but the rest are in excellent condition. Their round, nodular habit is a common aspect of their triclinic form, and all have a dull green color and a dull, waxy luster. Most are dimly translucent. They are accompanied by a large cluster of calcite prisms that seem to erupt from one of the Gyrolite clusters, and the hollow in the basalt host rock in which they rest is lined with countless tiny quartz crystals.
