Seymchan Meteorite Edge Cut with Pallasite in Caliper Stand

A Seymchan Pallasite Meteorite — Olivine Crystals Suspended in an Iron-Nickel Matrix

Pallasites are among the rarest and most visually extraordinary objects in the known universe — and the Seymchan is one of the most celebrated pallasite localities ever discovered. This edge-cut specimen reveals the defining feature of the pallasite class: gem-quality olivine crystals — translucent, honey-to-olive-green gemstones — suspended within a polished iron-nickel matrix that displays the Widmanstätten crystalline pattern of the host meteorite. The edge cut presents the specimen's full profile in cross-section, exposing both the olivine crystal distribution and the surrounding metal matrix in a single dramatic face. Held in a precision caliper stand, this 177 g specimen is one of the most scientifically significant and visually compelling meteorite forms available to private collectors.

Scientific & Mineralogical Profile

• Meteorite Classification: Pallasite — one of the rarest meteorite classes, comprising less than 1% of all known meteorites; formed at the core-mantle boundary of a differentiated asteroid parent body where molten iron-nickel from the core infiltrated the olivine-rich mantle
• Seymchan Classification: The Seymchan is classified as a transitional pallasite (PMG-an — Main Group anomalous), notable for containing both pallasite zones with abundant olivine and iron-rich zones with Widmanstätten patterning; this specimen's edge cut captures both mineral expressions
• Olivine Crystals: Gem-quality forsterite olivine ((Mg,Fe)₂SiO₄) — translucent to transparent crystals ranging from honey-yellow to olive-green; when backlit, the crystals transmit light like stained glass; the same mineral species as the gemstone peridot
• Iron-Nickel Matrix: The surrounding metal is an iron-nickel alloy (Fe-Ni) with kamacite and taenite phases; where etched, the Widmanstätten pattern is visible — the definitive authentication marker of iron meteorites
• Formation Origin: Pallasites formed at the core-mantle boundary of a fully differentiated asteroid — a body large enough to have separated into an iron core and silicate mantle through gravitational differentiation; the olivine crystals are mantle material, the iron-nickel is core material, mixed at the boundary zone
• Origin: Seymchan strewn field, Magadan Oblast, Russia — first discovered in 1967 by geologist F.A. Mednikov in the Hekandue River valley; pallasite zones identified in subsequent recoveries from 2004 onward
• Age: ~4.5 billion years — formed during the earliest differentiation of planetesimals in the solar system
• Stand: Precision caliper stand — scientific instrument-style display mount presenting the edge-cut face at optimal viewing angle
• Dimensions: 7.5″ H (stand included)
• Weight: 177 g (~6.2 oz)

Historical & Cultural Significance

Pallasites were first scientifically described by the German naturalist Peter Simon Pallas in 1772, who encountered the Krasnojarsk pallasite in Siberia and recognized it as unlike any terrestrial rock — the specimen now bears his name. The discovery of pallasites was pivotal in the history of science: their structure — crystals of a silicate mineral embedded in metallic iron — provided the first physical evidence that planetary bodies differentiate into distinct layers, directly informing our understanding of Earth's own iron core and silicate mantle. The Seymchan locality, discovered in the remote Magadan region of the Russian Far East in 1967, became one of the most significant pallasite finds of the 20th century when its olivine-bearing zones were identified in the early 2000s. Olivine — the mineral species of the gemstone peridot — has been prized since antiquity: the ancient Egyptians mined peridot on Zabargad Island in the Red Sea for over 3,500 years, calling it the "gem of the sun."

Metaphysical & Energetic Properties

• Pallasite Rarity: As one of fewer than 100 known pallasite localities, this specimen carries an energetic frequency of extreme rarity and cosmic significance — a material that exists at the literal boundary between a planet's core and mantle
• Olivine / Peridot Crystals: Peridot is a heart chakra stone of the highest order — associated with abundance, renewal, the release of old patterns, and the opening of the heart to new growth; its translucency amplifies light and positive energy through the specimen
• Iron-Nickel Matrix: Root chakra grounding, protection, and physical strength — the iron matrix anchors the expansive heart energy of the olivine to the physical plane
• Core-Mantle Boundary Origin: Formed at the deepest interior boundary of a planetary body — associated in metaphysical traditions with the integration of opposites, the meeting of fire (core) and earth (mantle), and the alchemical union of base and refined energies
• Crown Chakra: Extraterrestrial origin connects this specimen to cosmic consciousness, deep time, and the intelligence of the universe beyond Earth

Display & Care

• Display: Arrives in its precision caliper stand — compact and desk-ready; position near a light source or backlight to activate the translucency of the olivine crystals
• Rust Prevention: The iron-nickel matrix is susceptible to surface oxidation in humid environments; store in low humidity and apply a thin annual coat of Renaissance Wax or archival-grade clear lacquer to the polished metal surfaces
• Cleaning: Wipe metal surfaces with a soft, dry cloth only; avoid water contact on the iron-nickel matrix; never use acidic or alkaline cleaners
• Olivine Care: The olivine crystals are relatively fragile (Mohs 6.5–7) and sensitive to thermal shock — avoid sudden temperature changes and do not expose to prolonged direct sunlight, which can cause color fading in some olivine specimens
• Handling: Use clean, dry hands or cotton gloves — skin oils accelerate oxidation on the iron-nickel matrix
