Detailed Product Description

Natural Pyrite Stone – 6.84 Carat (7.52 Ratti)

This Natural Pyrite Stone weighs exactly 6.84 Carats (7.52 Ratti) with calibrated dimensions of 11 x 9 x 5 mm. Expertly shaped and polished into an exquisite Oval Cabochon, this Earth-mined mineral specimen displays an authentic, radiant brassy-yellow hue and a high-luster metallic surface reflection.

Mineralogical Identity & Physical Constants: Pyrite is an iron disulfide mineral with the chemical formula FeS2, crystallizing in the isometric (cubic) system. Celebrated historically as “Fool’s Gold” due to its sun-like metallic sheen, gemological testing separates it definitively from native gold: Pyrite produces a diagnostic greenish-black to brownish-black streak on unglazed porcelain, has a dense specific gravity of 4.95 to 5.10, and rates 6.0 to 6.5 on the Mohs hardness scale. Unlike soft, malleable gold, pyrite is brittle and cannot be scratched with a mild steel pocketknife.

Cultural & Ornamental Context: Pyrite has a distinguished heritage in global lapidary dating back to antiquity. Ancient Mesoamerican cultures polished large pyrite slabs into reflective ritual mirrors, and in Victorian fine jewelry, faceted pyrite was popularized internationally as “Marcasite.” Customary modern jewelry styles mount polished pyrite in Sterling Silver (925 Silver), Copper, or Panchdhatu bezel settings for statement signet rings and pendants.

Frequently Asked Questions

Is this Pyrite gemstone 100% natural and untreated?
Yes. This gemstone is guaranteed 100% Earth-mined natural Pyrite (Iron Disulfide, FeS2). It has not undergone any dye, resin filling, heating, or chemical stabilization, retaining its authentic metallic brassy luster and heavy mineral heft.
Why is Natural Pyrite commonly known as "Fool’s Gold"?
Pyrite earned the historic moniker "Fool's Gold" during historical prospecting eras because its shimmering brassy-yellow metallic luster resembled native gold. However, gemological testing easily separates them: Pyrite produces a diagnostic greenish-black streak on unglazed porcelain (gold produces a yellow streak), has a Mohs hardness of 6.0–6.5 (brittle and cannot be scratched by a knife), and has a specific gravity around 5.0 (gold is 15.0–19.3).
How does Carat weight compare to traditional Ratti for this stone?
This gemstone weighs 6.84 Carats, corresponding to 7.52 traditional Sunari Ratti (1 Carat = 200 mg; 1 Sunari Ratti ≈ 0.91 Carats). Both measurements are explicitly documented on your official laboratory test report.
How is the authenticity and laboratory certification of this Pyrite verified?
Every Pyrite gemstone includes an independent accredited gemological laboratory testing report verifying natural pyrite identity, cut dimensions, specific gravity (4.95–5.10), hardness (6.0–6.5), and untreated natural status. If you specifically require an additional report from GII, IGI-GTL (IIGJ), or GIA, you can select it directly from the certification dropdown on this product page upon request (official laboratory testing fees apply in advance on a non-refundable basis).
How should Natural Pyrite be stored to prevent sulfide oxidation and degradation?
As an iron sulfide mineral, Pyrite is chemically sensitive to moisture and humidity. Keep your Pyrite jewelry completely dry. Never immerse in water, ultrasonic machines, or chemical jewelry dips. Clean gently using only a dry, soft lint-free microfiber cloth, and store in a dry jewelry box with a silica gel desiccant packet to prevent surface tarnishing and sulfide breakdown.
