A slice across a stalactite or stalagmite, with a small brown dot, pale brownish centre and then glittery purple amethyst crystal points radiating out. The specimen is discreetly glued to a gold coloured stand. Do you know how to tell a stalactite from a stalagmite in situ? A stalactite has to hold on tight, a stalagmite might reach the roof. Amethyst is a February birthstone.
