"This is emerald, but the exact number contained in it emerald it is impossible to determine," says gemologist Jeff Necka, who studied the jewel. "The stone is the heterogeneity of color, and therefore, at least a quarter of its volume may consist of white beryl is a mineral which is the predecessor of the emerald, — he said. — The surface of the stone is very well painted, but I doubt that the green color extends to the full depth. In my estimation, in this case, it is advisable to talk about General stone, how about jewels, but the emerald interlayer with a thickness of 3-5 cm."
