Here is a very cool piece from Vestrafeltet in Malmberget, Sweden.
The quartz has grown in a way that makes it look like a very old piece, with hematite and small yellow stilbite crystals covering part of the stone (especially the backside).
The size is 87 x 100 x 82 mm, and the weight is 368 grams.
The specimen is undamaged except one of the smaller quartz crystals in the bottom that is cut off.
If you look underneath (as shown on the last picture) you will see that the quarts is more clear inside.
