Some of the largest and most displayable specimens of Wavellite have come from the Siglo XX mine in Bolivia as described by Mark Bandy. This piece does not disappoint featuring several, fine, large, whitish-yellow color, sphere-shaped radiating aggregate measuring up to 1.4 cm with some samller spheres with gem clear Quartz crystals on matrix. This is the largest, most impressive, most displayable specimen of this material that Ive ever had in my hands. It would be very difficult to replace this specimen from any locality. 27.3 x 13.7 x 11.0cm
