I recently made an inexpensive (but worth more) purchase from the local museum. They were calling it a small quartz cluster. Main crystal stands at 2.5" tall x 1 3/8" at it's widest but only 7/8" thick. What caught my eye & prompted me to buy it for the $6.00 it was labeled at was the second crystal partially embedded in the first. After getting it home I found that both have green phantoms as do the smaller crystals at the base. At least the ones I can see into do at any rate. Most are covered with a white chlorite or similar. I'll get some closeup pics of them later on. But for now, here are the pics I just took. Not the best, but far from the worst (I hope). First 2 in front of a black background which shows the crystal great, but not the phantom at that well. Others are in front of a tan background making the phantoms show better. First 2 also show the base crystals some. Last 3 pics show some of the phantom in the 2nd crystal.

No idea where it's from honestly. The display didn't say, but it could very well be from here. They have quite a bit of petrified wood from around here, so maybe, but since I also bought an amethyst cluster from Brazil from them a few years ago, I can't be sure.
