This thin blade is totally covered in microscopice hematite crystals, which glitter in different hues. It is very difficult to photograph well unfortunately! In some lights this piece seems more pink, in others it tends towards green. The specimen is from Minas Gerais, Brazil, and is mounted in a black glass base.
1/4 inch (0.6 cm) wide, 1/4 inch (0.6 cm) deep and 3/4 inch (1.9 cm) tall.
