Here is a nice sample of Quartz from Bardufoss in Troms, Norway
It measures 88 x 62 x 45 mm and the weight is 247 grams.
It is partly transparent, and got a got a razor sharp top.
You will see a white little damage right where the top of the crystal begins.
You will also see there is a smaller twin crystal.
