Great contrast with sharp and lustrous Neptunites against the white Natrolite. Dozens of micro crystals are on board with lots of the rare mineral Joaquinite. The largest Neptunites reach 2 CM and show reddish highlights with good lighting. Most crystals are perfect and terminated, but there is damage to 2 crystals. These could be removed to make a "perfect" specimen but they are not bothersome to me and the overall impact is fine. Older material collected in the 60s.
