Boltwoodite (very rich specimen)

Item Description

Bright, yellow, radial clusters of boltwoodite needles, a rare uranium silicate, dramatically fill a sculptural L-shaped vug lined with sharp, lustrous and translucent, brown calcite rhombs on this outstanding combination specimen from Namibia. SELDOM have we offered boltwoodite at auction and in this size and quality. It is actually a stunning and rare example of high quality. It IS a rarified level for a display quality example of the species, though, and is worth $1000 or more in my opinion. Such specimens as this are few and far between - smaller, or reference level pieces, are easy to come by however. These have been listed for the last 25-30 years as coming from the nearby Rossing Uranium mine, but are actually from this prospect.
