Nuummite is a gemstone formed from a mixture of two minerals from the orthoamphibole group: anthophyllite and gedrite.

Willemite, Calcite, Fluorite from the Garpenberg Mine in Sweden
The Garpenberg mine is located in Bergslagen, a very old mining area in the southern part of Sweden.
The mine is very active today and is one of Europe's most progressive underground mining operations. Collecting is not possible, and the few specimens that reach collector's hands are highly prized. The mineralogy is quite similar to that of Franklin NJ.
