This is a good matrix specimen of Hubnerite from one of the most famous classic Bolivian localities. There are a few sharp, bladed, black (a very slight red color will appear with strong lighting) crystals of Hubnerite which are associated with dozens of sharp, lustrous, translucent, "butterfly"-twinned crystals of pinkish-orange Monazite-(Ce) with gemmy Quartz crystals on matrix. The Monazite crystals actually show a color change from a pinkish-orange hue in sunlight to a whitish-yellow color in incandescent light. These specimens are not common from Siglo Veinte and this piece is one of the better specimens of the material that I have handled. The largest Hubnerite crystal measures 2.2 cm, and the largest Monazite twin measures 3 mm.
