I bought it to make jewelry and its just too big and I hate to break it up. It is gorgeous and has the original oxidized green rock matrix on bottom. There are some large single crystals which are the focal point. I see mineral inclusions in the crystals which are interesting also. Those specks are not dirt but inclusions inside the crystals which formed as the crystal grew.
2.5" long, 1.5" wide, 1.5" tall. a real beauty!!! Great mineral rock crystal specimen! Not a dinky little thing, a nice big chunk of genuine amethyst in it's natural state.
