This is a one-of-a-kind Seymchan pallasite meteorite specimen from Russia, featuring a dramatic half-cut surface with natural olivine crystals embedded within an iron-nickel matrix. The polished cross-section reveals a rare contrast of metallic structure, translucent yellow-green olivine, and natural outer crust, making it both a scientific specimen and a striking display piece.

Officially known as the Seymchan meteorite, this material was first discovered in 1967 in the Magadan Region of Russia. Seymchan was later reclassified as a rare pallasite meteorite, a type believed to originate from the boundary between an asteroid’s metallic core and rocky mantle. Its structure combines iron-nickel metal with olivine crystals, creating a natural record of ancient planetary formation.

The specimen weighs approximately 2546g and measures about 163 × 83 × 69 mm. Its iron-nickel body contains visible Widmanstätten patterns in metallic areas, while the olivine-rich zones show green to golden-brown crystal inclusions. The 1 cm reference cube shown in the photos is used for scale.

With its substantial size, natural texture, and rare cosmic origin, this Seymchan meteorite is ideal for collectors, museum-style displays, office décor, astronomy enthusiasts, and meaningful luxury gifting. Each piece is photographed individually, and the item you see is the exact specimen you will receive.

Lifetime authenticity guarantee. This is a genuine natural meteorite specimen, not artificial stone, replica, or ordinary mineral.

I. Official Name: Seymchan

Type: Pallasite (PMG-an, Main Group anomalous)

Discovery Date: June 1967

Discovery Location: Riverbed of the Hekandue River (tributary of the Yasachnaya River), Magadan Oblast, Russia

Coordinates: 62°54′ N, 152°25′ E

Discoverers: F. A. Mednikov (main mass), I. H. Markov (secondary mass)

II. Discovery History

1. June 1967: Geologist Mednikov discovered the 300 kg main mass.

2. October 1967: Markov found a 51 kg secondary mass 20 meters away.

3. Initial Classification: Samples taken only from the metal portion; mistakenly classified as a IIE iron meteorite.

4. 2004: An expedition discovered approximately 50 kg of new fragments; 20% of these contained olivine.

5. 2007: Officially reclassified as a Main Group pallasite (PMG-an).

6. Largest Fragment: Approximately 1.5 tons; currently housed at the Moscow Planetarium.

III. Minerals and Composition

- Matrix: Iron-nickel alloy (nickel content approx. 9.15%)

- Olivine: Translucent to transparent; emerald green to yellowish-brown; large, centimeter-scale crystals

- Accessory Minerals: Troilite, chromite, schreibersite, apatite, etc.

- Characteristics: High iridium (Ir) content → Classified as "anomalous" (an)

- Structure: Biphasic/Heterogeneous – Pure iron-nickel zones (showing Widmanstätten patterns)

- Olivine-rich zones (olivine embedded in metal)

VI. Olivine phase (Olivine, Fa₁₁.₆) composition

- Average formula: (Mg₁.₇₅₁Fe₀.₂₃₀Mn₀.₀₀₆)SiO₄

- Magnesium (MgO): 49–50%

- Iron (FeO): 11–12%

- Silicon (SiO₂): 38–39%

- Manganese (MnO): 0.2%

- Nickel (Ni): <110 ppm (very low)

VII. Other accessory minerals (trace amounts)

- Troilite (FeS): Fe 59.38%, S 38.11%, Ni 0.08%

- Chromite: Cr 35.45%, Fe 15.24%, Mg 43.71%

VIII. Key Characteristics

- High nickel (9.15–9.5%) and high iridium (~0.68 ppm) → Classified as PMG-an (Main Group anomalous pallasite)

- Low phosphorus and sulfur content, minimal impurities → Highly stable, resistant to rusting

- Dual-phase structure: Pure iron-nickel zones (displaying Widmanstätten patterns) + olivine-rich zones.

FANCYINGSECRETWhere You Wear the Universe.
Fancying Secret - Where You Wear the UniverseNot everything you carry has to feel heavy.Most days it's not the world that's overwhelmingIt's the constant noise in your headThe pressure to figure everything out.To be better, Faster, Stronger
To not fall behind.
But step back far enough, and something changes.What feels massive now becomes a passing moment.Because the truth is-
you're living inside something far greater than any single worry.

These pieces you wear were not made on Earth.
They traveled through space for over 4.6 billion years-through silence,impact,destruction and rebirh-before ariving here.
They don't just carry matt
They carry time.

At Fancying Secret,
we don't just turn meteorites into jewelry.We refine what was once raw, untamed,and unreachable into something you can actually wear-something that feels close, intentional,and beautifully human.everything from the universe is meant to be wornBecaus
But this is.

We're not here to give you answers.
We're here to remind you of a different perspective.
That you don't have to have everything figured out.
That youre allowed to feel small sometimes.
And that small doesn't mean insignificant.

When you wear it,
you remember:
You are not just in this moment.
You are part of something vast.
And somehow,
still enough.
