  • Here is a different one! This cluster features a very blocky, titanite crystal wedged between two microcline crystals. The titanite crystal has a weird notch, like it is twinned, but is not a twin law that I am familiar with. I took a second picture that did not turn out. I can send on along, if you with. Very cool!
