C&S-Marcasite-Genuine

Metallic shine and rich, neutral color make Marcasite the essential accent stone. Gleaming like finely polished silver, Marcasite was highly favored by Art Deco designers of the 20s and 30s. Today, the streamlined geometrics of that period are enjoying renewed popularity, as customers seek the glamour of Hollywood’s “film noir” era and its sophisticated styles.
