To keep prices low, we do not sort the crystals, which means you will get a variety of clarity and length. We purchase grade A crystals, but there will still be variances (Based on what they are currently mining). These are 100% natural stones, there may be some smaller or larger than average points and some may be fractured, imperfect, have inclusions (Other minerals that grow with the quartz), and dirt. Because of this, we always add a few extra grams of free weight to each order.
