Almandine, River Valley, Dana Township, Ontario

The "River Valley" locality has been known for many 10s of years and, in fact, there are probably several localities in that area. Deep red, almandine crystals are recovered from the coarse biotite schists of the area. The crystals show crystal forms that are the dodecahedron and trapezohedron with variations between. The crystals appear round but are always sharp crystals with many oscillating faces of the above isometric forms. Classic!

  • This specimen sports a couple of nice, deep red almandine crystals and a chisel-tipped terminated staurolite crystal. The almandine crystal is a dodecahedron that is modified by trapezohedron, with stria of the two forms. There are several staurolite crystals with one extra nice one protruding up out of the largest almandine crystal. One of the few nice combination specimens that I've seen.
