The Wanda Mines are one of the most surprising excursions from Iguazu Falls. Located just 40 km north of Puerto Iguazu in the heart of Misiones province, these open-pit mines reveal a geological treasure hidden beneath the red earth: enormous geodes filled with amethyst, quartz, agate and citrine crystals formed over millions of years inside volcanic basalt.
The guided tour takes you through the excavation sites where you can see the geodes in situ -- some as large as a washing machine, with deep violet amethyst crystals glinting in the sunlight. The experience is educational and visual: guides explain how the crystals formed, the geological history of the region, and how the stones are extracted and processed. After the tour, the mine's shop offers the chance to buy stones, geodes and jewellery at producer prices.

What to Buy
The mine shop offers raw stones, polished stones, geode halves, jewellery (rings, pendants, earrings, bracelets) and decorative pieces. Prices are significantly lower than in tourist shops in Buenos Aires or abroad, since you are buying at source. Amethyst geodes are the most popular souvenir -- small ones start from USD 10-20, while large display pieces can cost USD 100+.
Tip: The best value is in raw or minimally polished stones. The more a stone is processed (cutting, setting, polishing), the less advantage you get over retail prices. A beautiful raw amethyst cluster makes a stunning and affordable souvenir.
