An exceptional cluster of euhedral, sharp Betafite crystals, the largest of which is an amazing 1.8 cm across. These heavily modified cuboctahedrons are brown, with a vitreous waxy luster. Included in their surface are several reddish Zircon crystals - unusual! It is unusual to find these Betafites in such good-quality crystals and with a nice patina to them. Slightly radioactive, and rare in this quality.
