A stunning single GEM crystal 1.4 cm tall, perched nicely on a pedestal of matrix with a secondary smithsonite. The coloring on these are due to trace amounts of cobalt, but seldom are these pink smithsonites so transparent. You can actually read through this! Complete all around, though a few tiny dings exist.
