A HUMONGOUS example for this form of carletonite, which due to its size has also acquired an opacity not common to the others here. It is a bit rough-looking and is missing one corner at the bottom, but the size has a value and also makes it very impressive for the species, as far as the freestanding crystals go. One other thing about this, is that the demarcation between blue and white is so sharp and distinct, I have never seen the like.
