Nice natural quartz pieces to facet that is perfectly clear, which was cut to remove outside roughness, not synthetic quartz. The larger piece is about 4.5 inches long and around 2 inches thick, weight is estimated 350g The smaller ones are half the weight and size, which is around 3 inches long and 1.5 thick. Estimated 100-150g for each one that one is a little smaller but both are almost the same size. There is small damage only to some edges of the crystals but the inside is still perfect.
