Great gem-clear crystal with a delicate light yellow color. Many of the great Russian gem crystals were mined during czarist times, so this is probably a classic from that era. It is actually much better in person because, even with an excellent luster, the very slight frosting on most of the faces makes it difficult for the camera to see right through it. A killer thumb. 2.5 x 1.5 x 1.1 cm
