Frequently asked questions

• Is pyrite natural, or is it treated to get that metallic shine?

  Pyrite's metallic luster is natural — it's iron sulfide (FeS2), a sulfide mineral that takes a brilliant brassy-gold polish straight from the rough. Beads are typically cut, polished, and drilled with no color treatment, dye, or coating required. Some material is lightly waxed or sealed to slow oxidation, but most strands are sold as natural. If a specific treatment applies to the strand you're considering — ask before buying if it isn't specified. The bright gold flash you see is the stone itself, not a finish.
• Will pyrite tarnish or rust in finished jewelry?

  Yes, pyrite can oxidize over time, especially in humid environments or when in prolonged contact with skin oils, sweat, or perfume. The surface may dull, develop rust-colored spots, or darken — this is the iron content reacting with moisture and air. To slow it down: store finished pieces in a dry place with anti-tarnish strips or silica packets, wipe beads with a soft dry cloth after wear, and avoid wearing pyrite in the shower, pool, or gym. Pyrite suits earrings, necklaces, and occasional-wear bracelets better than daily-wear rings or pieces that see constant contact with skin.
• How does pyrite differ from marcasite, hematite, and chalcopyrite?

  All four are metallic-luster minerals seen in the bead trade. Pyrite (FeS2, cubic crystal system) shows a brassy pale-gold color and often forms perfect cubes in rough. Marcasite is the same chemistry but a different crystal structure (orthorhombic) — less stable, rarely cut as beads, and the term is often misused in jewelry to mean small faceted pyrite. Hematite is iron oxide, darker silver-gray to gunmetal, and more stable against oxidation. Chalcopyrite is copper-iron sulfide with a deeper gold tone, often artificially treated to produce iridescent "peacock ore" surfaces. Pyrite sits in the middle: brighter than hematite, more stable than marcasite.
• What designs and metals pair well with pyrite beads?

  Pyrite's brassy gold tone reads close to yellow gold and brass, making it a natural companion to gold-fill, vermeil, and antiqued brass findings. It also contrasts cleanly with oxidized sterling and gunmetal. Designers use it as a metallic accent between matte stones — labradorite, moonstone, black onyx, lapis, and rough-cut quartz all sharpen against pyrite's reflectivity. Cube and heishi cuts work well as spacers and rhythmic accents; rounds carry full strands or focal sections. Because the luster is bold, even small beads (4–5mm) read as metal hardware in a strand. Avoid pairing with stones that need gentle cleaning solutions pyrite can't tolerate.
• How should I clean pyrite jewelry without damaging the surface?

  Use a soft dry cloth for routine cleaning — that's the safest approach. If beads need more, a barely damp cloth with a tiny amount of mild soap works, but dry the strand thoroughly afterward and let it air out before storing. Avoid: ultrasonic cleaners (vibration can fracture beads along cube cleavage planes), steam cleaners, ammonia-based jewelry dips, and any acidic solution — sulfides react with acids and can release sulfur compounds. Don't soak pyrite. After cleaning, store separately from softer stones since at Mohs 6–6.5 it can scratch most organics, fluorite, and calcite-based materials.
