    Description

    You see here real photos and analytica of the lot.
    25 mm polished epoxy preparate with mounted Copper-Silver
    micronugget with abundant inclusions of crystals native Tungsten from
    Tabornoe gold deposit, Olekma area, SW part of Sakha republic, Eastern Siberia, Russia
    . This material was described in recently published article -
    Mills S.J., Kartashov P.M., Kampf A.R. e.a. (2021)
    Native tungsten from the Bol'shaya Pol'ya river valley and Mt Neroyka, Russia.
    // Mineralogical Magazine, v. 85, p. 76-81.
    For the moment confirmed native Tungsten is known from 5 localities - in TL on Prepolar Ural, in 3 points of Moon surface and from Tabornoe deposit. And only from here it is possible to obtain "matrix" specimens of Tungsten. But this material is strictly limited, because it come from the single drill hole from depth 64 and 120 m. Total quantity of known micronuggets with Tungsten is not more than 100 and most of them were mounted in two collective preparates for investigation. So only a few micronuggets are still available for collectors.
    For exact size of the micronugget and Tungsten crystals themselve look at micrometer bars at SEM images. The sample belongs to rare group of well recrystallized micronuggets with excellent individualized Tungsten crystals (visible under binocular). A sample of such quality is proposed on eBay for the first time.
    Don't miss this rare possibility!
    Together with the specimen you will receive its certificate with the Tungsten quantitative microprobe analyze, SEM photo with marked place of analyze, EDX spectrum, description
    and my personal handmade "sign of quality"
    (without it certificate isn't valid).
