This is a perfect specimen, hands down. A -twinned- Fluorite with exceptional luster and saturated color zones, contrasted perfectly by gemmy towers of Chlorite included Quartz that are perfect in both size and composure. How could this specimen get any better? (not a real question; it can’t, it’s already formed)
