A slice across a stalactite or stalagmite, with two central "eyes", a white quartz central area and then glittery purple amethyst crystal points radiating out. The specimen is discreetly glued to a white plastic support. Do you know how to tell which is which in situ? A stalactite has to hold on tight, a stalagmite might reach the roof. Amethyst is a February birthstone.
