  • Ultra Rare Xenotime-Yb CRYSTAL Texas

    Burnet County, Texas

    Franklin Roberts, of Austin Texas, having some serious luck with a bit of skill and knowledge, finding some amazing things in the pegmatites of the Llano Uplift. You can find them for sale here, on!
    The mineral is all but completely hard to find, with samples being micros, mostly just found as grains in sand. This amazing find is one great sample of Xenotime-Yb, verified, and quite possibly a twin. Weighing in at 6.75 grams, this mineral has the highest concentration of the native element Ytterbium. This very might well be one of the best Xenotime-Yb crystals in existence.
