This piece is perhaps the most starkly aesthetic and sculptural of the lot, with a single dramatic, lemon yellow crystal just flying up off the matrix, braced in its freefall by a little crossbar crystal. That crystal is the sharpest in the lot, as well....very equant, and very complete all around with no damage or dings. It is 4 cm long, 1.5 cm thick. The matrix is hausmannite and hematite, coated by a rich carpet of soft oyelite. I have NEVER seen such an example, on contrasting matrix and so 3-dimensional, for sale.
