A highly translucent, naturally etched beryl crystal, with enough residual blue color to rightfully be labeled as aquamarine. Although numerous collectors eschew etched crystals, we must remember that such crystals illustrate a significant part of mineral crystal growth. Crystal formation is a reversible, equilibrium process; the same fluids which deposit a crystal can also dissolve this crystal. This specimen records a time at which dissolution had begun, but the crystal had not yet been fully consumed and lost forever. Incomplete on the back where removed from matrix (or cobbed from cutting rough) but otherwise great condition.
