NE43E7: Look out for this one: it is marvelous. The prismatic Fluorapatite crystals are large, aerial and have a great color that is somewhere between blue and green. That said please note that, as you can see in the detailed photo, there is a significant contact on one of the upper faces of crystals. This is where there used to be some Siderite (I know this as I removed it). When you display this specimen the contact is not visible, but you see it when you hold it in your hands. So the importance you give to this contact will affect your wish to have this one in your collection. For me, given the beauty and quality, the fact that there is a contact (this is not damage) due to the former Siderite is acceptable, especially given that it is very difficult to find such specimens at a reasonable price.
