Picture shows EXAMPLES of our stock of Natural Smoky Quartz Crystals . You will receive a "pot-luck" crystal of variable quality, length, width - perhaps with some unusual attributes. Some even have natural citrine aspects as well! You will receive one of minimum weight 6 grams. For examples of size etc. refer to picture.
These are useful grounding and clearing crystals - some have some unusual or rare attributes, so may make good meditation pieces.
