Description

Very different piece from the classic locality!On the top of display of a matrix of thin, pointed hedenbergite crystals grows an adradite crystal with different, bizarre crystallization than any other from the locality! It shows the same phantoms, with different color, high sharpness and melt plastic luster! On another edge there is a group of smaller grey crystals! Grey garnet is something rare on it's own. Some inclusion has given the color and left textbook faces!On the matrix there are even quartz crystals!
