What is marcasite jewellery?

Definition
Marcasite jewellery uses small, faceted stones cut from iron pyrite, set into silver or white metal to create a dark, glinting sparkle that is more subdued than diamond but far more affordable. Despite the name, the stones used in jewellery are almost always pyrite rather than true marcasite, as pyrite is more stable and harder; jewellers have used the two names interchangeably for centuries. The stones are typically cut in a rose cut style and set very close together or individually in silver collets. The style was especially popular in Georgian, Art Nouveau and Art Deco jewellery, and vintage marcasite pieces are widely collected.
Frequently asked questions
- Is marcasite real silver?
- The settings in marcasite jewellery are usually sterling silver or white metal, so many pieces are genuine silver. The stones themselves are pyrite rather than a precious gem. Authentic vintage pieces will often be hallmarked on the silver mount.
- How do you care for marcasite jewellery?
- Keep marcasite dry and away from water, as moisture can loosen the settings and cause pyrite to oxidise. Clean it with a dry or barely damp soft cloth, store it away from humid conditions, and never use ultrasonic cleaners or harsh chemicals.
- What period is marcasite jewellery from?
- Marcasite pieces were made extensively in the Georgian period from the late 1700s, continued through the Victorian era, and enjoyed a strong revival in Art Nouveau and Art Deco jewellery of the early twentieth century. Vintage pieces from the 1920s and 1930s are among the most popular with collectors today.
