This unusually large tanzanite is not just large, but is an elegant cluster as well. It is simply incredible for display impact. The cluster is heated of course, to get this uniform color (though probably not fully treated to saturation, and so it is hard to tell for sure just by looking). Out of the whole cluster, there is only one contact repair in the middle (seamless). Think, how many tanzanites have you seen this size, and in a cluster? The least important and rightmost crystal is contacted otherwise all terminated around. The front is pristine. The luster is SUPER GLASSY and combined with the color and size, this is why I say it has such impact that it almost glows at you from across the room. I am sure there are a few more larger ones out there, but I do not know where. This is a MAJOR piece of museum caliber, and then some. Comes with custom lucite base for easy display.
