    RARE CANADIAN MULTI-COLOR FLUORESCENT
    Long Lake Zinc Mine, Olden Township, Frontenac Co, Ontario, Canada
    Also known as the Lynx Mine, the Long Lake Zinc Mine has quietly been producing some of the most spectacular multi-color fluorescent mineral specimens in the world since at least the early 1960's. Though yielding occasional specimens since then, the only time a truly noticeable amount of pieces appeared on the market was during the mid to late 1990's, when the present specimen was made public; by the early 2000's they had largely disappeared again, having been absorbed into an eager market. And no wonder - although the overall tones are usually on the muted or pastel side, these specimens frequently present beautifully aesthetic patterning, rarely matched elsewhere, including in pieces from the famed Franklin area. Measuring 14 x 7 x 4¼ inches, this example resembles nothing so much as a giant psychedelic peanut and is an outstanding piece even for this fine locality. Composed of the Grenville Formation marble and its accompanying minerals, and activated with the help of trace elements from the zinc mine, it contains red-orange fluorescent calcite, resembling the dying embers of a fire, along with bands of what seems to be yellow-white fluorescent diopside (although could possibly be the much scarcer fluoborite). Bright yellow fluorescing chondrodite also appears, in similarly arranged bands of spots, as well as what are probably veinlets of dolomite, brilliant blue streaks cross-cutting these other mineral bands in a sub-parallel trend: a rare and desirable response for this mineral. In addition, a non-fluorescent brown vein streaks across the specimen roughly parallel to the Dolomite veinlets and has apparently imparted a halo of white fluorescent calcite about ¼-inch thick to either side of the vein. All these fluorescent responses are visible under shortwave ultraviolet rays and combine to produce a superbly patterned, exceptionally large, world class 5-color fluorescent specimen of museum-worthy quality.

    Provenance: Ex Hugh Ronemus Collection
