Benitoite crystals were occasionally found as 'floaters' that had weathered out of the host crossite amphibole rock matrix. This is an example of a single large crystal with blue-gray color and a rough surface caused by the amphibole inclusions. Even though it's not dark blue in color, it does have the same 'cornflower blue' fluorescent color when seen under shortwave UV lighting.
