Tis ultragemmy 2.5 x 2.5 x 7-cm-long crystal has to be seen to be believed. It is so gemmy, clearn, clean and limpid that you look right through to the underlaying matrix and its almost hard to focus on the outer faces of the crystal itself in its midpoint, the eye is so drawn to look through it. Just a common quartz, but of truly top quality that is shocking. The piece is beautifully trimmed and so displays well on a natrual pedestal of dolomite crystals. I have not seen a piece like this, in overall aesthetics, from Brazil or anywhere.
