Pakistani peridot is the trade designation for peridot — gem-quality forsteritic olivine — produced from deposits in northern Pakistan, principally from the Naran-Kaghan, Suppat, and Sapat areas of Khyber Pakhtunkhwa, with additional production from the Kohistan and Indus suture zones. The deposits sit in ultramafic and ophiolite host rocks and have produced commercially significant volumes of fine peridot since the 1990s. Pakistani peridot is now an established global source, frequently competing with Burmese, Chinese, and Arizona-origin material in the international market and offering the trade reliable supply of clean medium-to-large stones in the desirable bright-green colour range.

Geological setting

Peridot is the gem variety of olivine, a magnesium-iron silicate with the formula (Mg,Fe)₂SiO₄, occurring in mafic and ultramafic igneous rocks throughout the world. Gem-quality material requires the magnesium-rich forsterite end of the olivine series, with iron content low enough to produce a pure green colour rather than the brownish or yellowish tones of more iron-rich olivine. The Pakistani deposits provide this composition through their ophiolite-suite host rocks: ancient oceanic crust and underlying mantle peridotite obducted onto the continental margin during the Himalayan collision.

The Naran-Kaghan and Suppat deposits in Mansehra District, Khyber Pakhtunkhwa, host the bulk of the commercial production. The peridot occurs in serpentinised dunite and harzburgite — mantle-derived ultramafic rocks that have been partially altered to serpentine through interaction with hydrous fluids — with the gem material concentrated in less-altered pockets. Mining is by surface and shallow-tunnel operations at altitudes between approximately 4,000 and 5,000 metres, with seasonal access limited by snow and weather conditions in the high Himalayan terrain. The Sapat area to the east contains additional deposits with similar geological character.

Colour and quality

Pakistani peridot typically displays medium yellowish-green to pure green colour, with the finest stones reaching the bright spring-green hue that the trade considers ideal for the species. The colour position varies with iron content, with the lower-iron Pakistani material tending toward purer green and the higher-iron material showing more pronounced yellow-green character. Tone runs medium to medium-dark, and saturation is typically strong in the better material. Brownish or olive-tinted stones are uncommon in Pakistani production, since the ophiolite source rocks generally provide the magnesium-rich olivine composition that yields cleaner colours.

Crystal size in the Pakistani deposits is a particular advantage of the source. Faceted stones above 20 carats are not unusual, and exceptional material has produced stones above 100 carats. The combination of size, colour, and clarity makes Pakistani peridot competitive with the famously fine Burmese material from the Mogok region — historically the global benchmark for peridot quality — at meaningfully lower price points.

Inclusions and identification

Pakistani peridot shows a characteristic inclusion suite that is documented in the gemmological literature. The most frequently observed features include thin, disc-shaped inclusions known as lily pads — partially healed fractures with a central dark crystallite and surrounding healing zones, oriented along crystal directions — together with chromite and biotite crystallites, fluid inclusions, and occasional needle-like growth tubes. Lily-pad inclusions are common to peridot from many sources but are particularly well developed in the Pakistani material.

Trace-element analysis can support origin attribution among the major peridot sources, though the discrimination between Pakistani, Burmese, and Chinese material is less clear-cut than for some other species because the ophiolite-suite source rocks are geochemically similar across producing localities. GIA and other major laboratories will issue origin opinions on peridot where the analytical data support a confident attribution.

Treatment

Pakistani peridot is generally untreated. Heat treatment of peridot is not commercially practised — the species' colour is not amenable to enhancement by heat, and the inclusions characteristic of the material are not treated by oil or fracture filling in normal trade practice. Buyers can typically assume that Pakistani peridot is in its natural condition, though laboratory verification is advisable for high-value pieces.

Position in the trade

Pakistani peridot occupies a strong commercial position in the global market. Pricing for fine Pakistani material runs below the Burmese benchmark — the Mogok-region peridot that auction houses and high-end retailers have historically marketed as the finest of the species — but above commercial Chinese, Arizona, and Vietnamese production. The price gap with Burmese material has narrowed somewhat as Pakistani sources have demonstrated consistent supply of fine-quality stones, and some buyers prefer Pakistani peridot for the combination of quality and accessibility.

For dealers and retailers, Pakistani peridot offers reliable supply across the size range from melee to large feature stones. The ophiolite-source material is often clean enough to support faceted stones in the five-to-twenty-carat range that suit pendant and dinner-ring applications, and small calibrated stones are available for set-jewellery production. Cabochon material is less common — Pakistani peridot is typically clean enough to facet — but is occasionally produced from heavily included rough.

Setting and care

Peridot has a hardness of 6.5 to 7 on the Mohs scale, making it suitable but not ideal for ring use; rings with peridot centres benefit from protective settings such as bezels or recessed mountings. The species shows distinct cleavage in two directions, and tool selection during setting and resizing must respect the cleavage planes. Heat sensitivity is a practical concern — peridot can fracture under thermal shock and should be removed from settings before torch work is performed nearby. Cleaning should be by mild soap and warm water; ultrasonic and steam cleaning are not recommended for stones with significant inclusions.

In the trade

Pakistani peridot reaches the international market through Peshawar, Bangkok, and Jaipur dealer channels, with both rough and cut material widely available. Reputable dealers can typically document Pakistani provenance through the supply chain, and major laboratories can confirm origin where the analytical data support it. For buyers commissioning fine peridot pieces, Pakistani material is often the practical first choice for stones above five carats, with Burmese material reserved for the highest tier of the bespoke market.
