By any standards, this is a magnificent Gold specimen. Just look at those razor-sharp skeletal ribs that are so well preserved from the original HUGE hoppered crystals that were simply compressed. You can easily see both the rounded surfaces of the cubes and a few sharp crystal edges. The hoppered ribs following the octohedral lines give this the look on a swirling tornado. Amazing. A truly world class gold specimen and for nevada all the more so! This was one of the two outstanding specimens in the lot, which the collector had obtained by prospecting almost every year for the last 30 years!
