Fluorite in Quartz Fluorite in Quartz Fluorite in Quartz

Superb example of this rare occurrence, a one time find as far as I know. Purple/blue Fluorite inside a long Quartz crystal. Most from this find were smaller Quartz crystals and had lots of surface pitting caused by Fluorites that were once only partially inside the Quartz and later dissolved away (leaving the pitting). With this specimen, all the Fluorite are located entirely within the Quartz, and the Quartz itself is undamaged. This is as good of quality as I've seen for this material and in the upper size range. Much better than pics.
