Miners discover a one-of-a-kind amethyst crystal inside a large basalt geode in the Santa Rosa mine in Uruguay’s Artigas ...

The three-meter tall amethyst geode - a hollow rock filled with amethyst ... arrived at The Crystal Caves in November 2007 and two large cranes were needed to lift her into her current position.

It also has large amethyst geodes from Brazil. Returning this year are the demonstrations on how to cut arrowheads and geodes or polish cabochons, which will take place outside the venue.
