Franklin, Sussex Co, New Jersey
These two exceptional Short-Wave fluorescent specimens are a Mangan-Axinite specimen, and a Franklin 5-color piece containing Esperite. The triangular Manganaxinite is of the type referred to amongst collectors as the "burning coals" type, for obvious reasons. Associated with it is the shortwave green fluorescent Willemite of the "exsolution" variety. Two other minerals occur mainly on side and back faces of the piece, one probably Xonotlite, fluorescing a faint blue; and the other a yellowish-orange fluorescent, most likely: Clinohedrite. The 5-color SW-UV specimen of triangular shape displays spots of brilliant yellow fluorescing Esperite along with: bright purple fluorescing Hardystonite , a band of red-orange fluorescing Calcite speckled with brilliant green fluorescent Willemite. There is also a patch of wispy, bright yellow-orange fluorescent Clinohedrite on the Hardystonite and some non-fluorescent black Franklinite and all five shortwave ultraviolet fluorescent minerals can be seen on the main face at the same time. The Mangan-Axinite measures 3 x 2 1/4 x 2 1/8 inches (7.6 x 5.7 x 5.4 cm), while the multi-color specimen measures 3 x 2 1/4 x 7/8 inches (7.6 x 5.7 x 2.2 cm).

Provenance: ex. Hugh Ronemus Collection
