There are several groups of Ernienickelite on this specimen. These were hard to find and you will need at least 40x to see the outlines and platyness of these crystals. The main group at the tip of the green arrow has at least three subparallel crystals. They are very thin with somewhat hexagonal outlines. The other group, especially the group to the left of the arrow also contain good crystals. The matrix, like the description states is a chalcedony. But the crystals are in a tiny vug lined with uartz crystals and an unidentified brown mineral. Excellent rich specimen with an Excalibur-Cureton label. Extremely rare. Could be the last Ernienickelite you'll ever see.
