Sparkle for days, this miniature provides some of the best luster from this find. Under the scrutiny of a hand lens, you can pick out individual sharp chalcopyrite crystals on the surface of the balls! The deep purple color is accented by a 1.7cm ball bifurcated between bright purple and teal. Smaller centimeter sized balls accentuate the main 2.2cm orb. A really sweet piece!
