Parker Mine, Laurentides
3.3 x 2.8 x 1.7 CM (thumbnail)
A sharp and lustrous Spinel octahedron is perched on a matrix shard. In excellent condition, the Spinel has distinct edge and corner modifications and is well exposed from the enclosing rock. This is from the Parker Mine in Québec which was a Mica mine and was at one time the source of fine Spinel crystals in Feldspar like this example.
