How do I Know if my Jewellery is Marcasite? Marcasite is a type of iron sulfide mineral that is often used in jewelry.
It’s a relatively inexpensive stone, but it can be difficult to distinguish from other types of jewellery stones, such as pyrite. At London Vintage we’ve been using it in our jewelry designs for decades.
Time needed: 10 minutes.
Here are some ways to tell if your jewelry is marcasite:
- Look at the colour.
Marcasite can either be a silvery-white or yellowish color, or sometimes brown or black. Pyrite, on the other hand, is typically a brassy yellow color.
- Check the luster.
Marcasite has a metallic luster, while pyrite has a more glassy luster.
- Do a streak test.
Rub the stone against a piece of unglazed porcelain. Marcasite will leave a greenish-black streak, while pyrite will leave a brassy yellow streak.
- Look at the setting.
Marcasite is typically set in silver or gold. Pyrite is often set in base metals, such as brass or copper.
- Check for a hallmark.
Some jewelry may be stamped with a hallmark that indicates the metal content. If the jewelry is stamped with “925,” it is made of sterling silver. This is a good indication that the jewelry is real marcasite, as marcasite is typically set in silver.
If you are still unsure whether your jewelry is marcasite, you can take it to a jeweller for appraisal. they’ll be able to use their expertise to identify the stone and give you an accurate assessment of its value.
