Nevada Black Rock Desert

Some of the best and most distinctive Thundereggs are from locations now closed off and unavailable. In this case, the area has been designated a wilderness area by the Bureau of Land Management (BLM) and closed. Wilderness or not, the Black Rock Desert Thundereggs are still some of our personal favorites, for that wonderful brick-red matrix and especially if we find a mossy plume specimen. The Black Rock Desert is located in the northwest corner of Nevada, north of Gerlach and west of Winnemucca. The lands there are all wilderness protected areas, a few old personal claims and Indian Reservation areas. Some rockhounding is still permitted with strict limitations.

Rare Mossy Plume Agate Black Rock Thunderegg Slab

This is a wonderful example of the “Best of the Best” of the Nevada Black Rock Thundereggs. This stunning large and thick polished slab was obtained direct from the owners who mine these Thundereggs in McDermitt, Northern Nevada. This specimen is laced with swirls of beautiful mossy golden plume and has a window of opaque banded Chalcedony. This is a really rare piece, as most of the Thundereggs from the Black Rock Desert area do not have anywhere near the amount of mossy plume that this specimen contains and are normally much smaller. This slab is nicely polished on one face and contains natural fault cracks.

This specimen weighs 0.53 lb (243g) and measures 6 x 4 x 0.31 inches (153 x 101 x 8mm)
