The yellow-to-brown metallic sheen of this round marcasite gemstone is reminiscent of old sepia-toned photographs, making it a perfect choice for jewelry that has a vintage style.
Marcasite is composed of iron sulfide and, while it is closely related to pyrite, it has a distinctly different crystal structure. Because its structure is orthorhombic (rather than cubic like pyrite), marcasite is more suitable for cutting and faceting. When polished, the stone has a bright metallic luster, and ranges in color from pale yellow to brown. Jewelry made from marcasite dates back to ancient times and the folklore surrounding this gem holds that it can dispel negative energy and enhance communication skills.
Round-cut gemstones are highly popular and the most commonly available. Rio round gemstones are calibrated for size and hand inspected to ensure maximum attractiveness.
