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.

FANCYINGSECRETDove indossi l'Universo.
Fancying Secret - Dove indossi l'UniversoNon tutto ciò che porti deve sembrare pesante.La maggior parte dei giorni non è il mondo ad essere travolgenteMa il rumore costante nella tua testaLa pressione di dover capire tutto.Essere migliore, più veloce, più forte
Per non restare indietro.
Ma fai un passo indietro abbastanza lontano, e qualcosa cambia.Ciò che ora sembra enorme diventa un momento passeggero.Perché la verità è-
stai vivendo dentro qualcosa di molto più grande di ogni singola preoccupazione.


Questi pezzi che indossi non sono stati fatti sulla Terra.
Hanno viaggiato nello spazio per oltre 4,6 miliardi di anni – attraverso silenzio, impatto, distruzione e rinascita – prima di arrivare qui.
Non portano solo materia
Portano il tempo.


In Fancying Secret,
non trasformiamo solo meteoriti in gioielli.Rifiniamo ciò che un tempo era grezzo, selvaggio e irraggiungibile in qualcosa che puoi effettivamente indossare – qualcosa che si sente vicino, intenzionale e splendidamente umano.Tutto dall'universo è destinato ad essere indossatoPerché
Ma questo lo è.


Non siamo qui per darti risposte.
Siamo qui per ricordarti una prospettiva diversa.
Che non devi avere tutto sotto controllo.
Che ti è permesso sentirti piccolo a volte.
E che piccolo non significa insignificante.


Quando lo indossi,
ricordi:
Non sei solo in questo momento.
Fai parte di qualcosa di vasto.
E in qualche modo,
sei ancora abbastanza.
