Due to its beautiful glittering metallic luster, many cultures have worked this material into objects of beauty. The Ancient Greeks made jewelry from marcasite. The Incas of South America polished large slabs of it as decorative objects. Gem cutters in the Victorian Era faceted this material into stones with flat backs. This popular style was known as the flattened-rose cut. Jewelry makers set them in white metal settings, such as rhodium-plated silver. Marcasite protects from negative energies. It teaches us that negativity drains our strength, and helps us to forget about emotional scars, hatred and grudges.
