3.14 ct PERIDOT – KASHMERE

### Kashmir Peridot

Kashmir Peridot from the legendary, ultra-high-altitude pegmatite exposures of the Indus-Kohistan region represents the “magnesian-silicate-crystallization” absolute peak of the mineral world. An exceptional, gem-grade variety of Olivine (Forsterite), it is a species I have always respected for its “electric-lime” to “deep-vibrant-meadow” green body color and its status as a masterpiece of “mantle-derived” structural discipline. While typical peridot is often found as small, basalt-hosted grains, the classic old-stock specimens discovered in the high-alpine valleys bordering Kashmir represent an extraordinary mineralogical anomaly. For the specialist, a top-tier old-stock Pakistani Kashmir Peridot is a prize of extreme fluid fraction; it offers a magnificent vitreous luster and a “luminous” presence that makes it a true “high-vibration” asset for the systematic vault. As an artist, I find the soft, “neon-olive” depth and the “razor-sharp” transparency of these monumental crystals to be one of nature’s most sophisticated and “mysterious” palettes.

The Heritage & Discovery

Historical Significance
Kashmir Peridot is a vital species for understanding the complex interaction between hydrothermal fluids and deep-seated ultramafic rock layers within tectonic collision zones. Historically, when the historic deposits near the Soppat alpine pastures were first brought to light in the mid-1990s, they completely shattered the historical limits of what was thought possible for the species’ size and saturation. In the world of fine minerals, a faceted old-stock Kashmir Peridot elevates an ancient mantle silicate to a natural, “optical-phenomenon” brilliance, which stands as a symbol of alignment and crystal clarity. It serves as a reminder that when volatile fluids react under perfectly undisturbed, extreme pressures high in the mountains, gargantuan, gem-clear crystal groups can form within the metamorphic matrix, turning a traditional birthstone into a dynamic, light-channeling masterpiece.

Discovery
While peridot has been mined since antiquity on the island of St. John’s in the Red Sea, the groundbreaking discoveries in the high-altitude territory of northern Pakistan during the late 20th century completely redefined the mineralogical benchmark for the species’ crystal size and gem-grade transparency. Scientifically, it is a magnesium iron silicate. Its discovery in the remote, snow-bound peaks overlooking the Kashmir border provided mineralogists with the first look at crystals thick and clean enough to be fashioned into world-class, multi-carat gems with minimal inclusions. My own respect for this material grew from observing its “reflective” depth; specifically, the way its light-channeling crystal lattice projects a “sharp,” unbroken neon green flash—a visual impact that is unmistakable to the trained eye.

Important Locations
The undisputed world capital for the finest “aesthetic” old-stock peridot is the Soppat pegmatite and mining field located in the Mansehra-Kohistan district, nestled against the jagged mountain passes of the Pakistani-administered Kashmir region. These high-altitude alpine specimens set the global benchmark for crystal density, vivid chromium-rich coloration, and “sharp” termination definition. For the vault, I prioritize the historic 1990s old-stock material for its unmatched “porcelain-neon” saturation and its status as a rare-phenomenon masterpiece of Central Asian alpine mineralogy.

Mineralogical Profile

Description
Kashmir Peridot is an iron-bearing magnesium silicate that crystallizes in the orthorhombic system. It sits at a 6.5 to 7 on the Mohs scale, making it a highly desirable and durable jewelry gemstone, though its distinct cleavages and sensitivity to rapid thermal shock mean it must be fashioned with extreme lapidary care and handled gently to preserve its “razor-sharp” internal facets and highly polished surfaces. It is characterized by its vitreous luster and its unmistakable, “vivid chartreuse to deep emerald-green” color palette.

The defining trait of an old-stock Kashmir Peridot is its rich, oily body color, which is frequently enhanced by traces of chromium and can host tiny, microscopic needle-like inclusions of Ludwigite or Magnetite captured within the orthorhombic lattice. It possesses a high refractive index running from approximately 1.65 to 1.69, yielding a notable double refraction (birefringence) that splits light entering the gem, and a specific gravity (SG approx 3.2 to 3.4) that reflects its iron-magnesium framework. Because it forms in unique metamorphic veins, it is often found in association with Magnetite, Ludwigite, Acicular Tremolite, and Albite. When I select a piece for the collection, I look for a perfectly cut, “razor-sharp” table that displays seamless color consistency under a single light source without dulling, highlighting the sophisticated, three-dimensional geometry of the mineral’s growth. It is a light, high-vibration mineral that offers a unique, “aqueous-porcelain” beauty unlike any other volcanic variety.
