- Vesuvianite With Groutite
- Small Cabinet, 6.1 x 3.5 x 3.4 cm
- Jeffrey Mine, Asbestos, Quebec, Canada
This large and undamaged matrix specimen is covered with gemmy, lustrous, apple green crystals of vesuvianite, to 2.0 cm in length. There are also elongated 2 mm crystals of an opaque, dark green, mineral scattered on several vesuvianite crystals, which have been analyzed as acicular groutite, a manganese oxide. This is a very good, relatively large specimen anyways, but the groutite adds a neat touch.
