382g Peridot on a Large Magnetite Matrix Specimen — Sapat, Kohistan, Pakistan
type: Product
description: This is green olivine (peridot) crystals embedded within a dense, dark magnetite-rich ultramafic matrix. The specimen was collected from Sapat, Kohistan — a locality in northern Pakistan recognized among geologists for its mafic and ultramafic rock sequences, including dunite and harzburgite, which represent material derived from deep within the Earth's mantle. Specimen Details Stone Names: Peridot (Olivine), Magnetite Specimen Type: Fine Mineral Specimen — On Matrix Weight: 382 Grams Dimensions: 85mm × 65mm × 30 mm Origin: Sapat, Kohistan, Pakistan Rarity: Uncommon to Rare Treatments: 100% Natural — Earthly Mined, No Treatments Authenticity: Genuine Condition: Good About Peridot Specimen with Magnetite The specimen has been photographed with macro to show multiple angles under controlled lighting. The peridot crystal — vivid apple-green in color — sits prominently on the upper face of the matrix, with visible translucency under direct light. The surrounding magnetite host is dark grey to near-black, with a rough, layered surface texture showing areas of serpentinization. Geological Context Sapat, Kohistan is part of the Kohistan Island Arc — a geological terrane accreted onto the Asian plate, known for exposing deep crustal and upper mantle rocks at the surface. Peridot found here occurs in its primary geological setting: directly within the ultramafic host rock rather than as a loose or secondary deposit. The magnetite in this specimen is interpreted as a product of serpentinization, where hydrothermal fluids altered the original olivine-rich rock. This association — peridot preserved within its original mantle-derived host — is less common than matrix-free peridot specimens and is of interest to collectors focused on geological context and provenance. Frequently Asked Questions Q: What is the difference between peridot on matrix and loose peridot crystals? A: Peridot on matrix means the olivine crystal remains attached to its original host rock, preserving the na…
