Mineralogical Identity & Physical Constants: Peridot is the gem-quality variety of Olivine (magnesium iron silicate, (Mg,Fe)₂SiO₄), specifically the forsterite end-member. Notably, Peridot is an idiochromatic gemstone: its distinctive yellowish-green to olive-green coloration is caused by intrinsic divalent iron (Fe²⁺) that forms an integral part of its chemical structure, rather than trace impurities. Under gemological testing, it exhibits a refractive index of 1.654 to 1.690 with strong diagnostic birefringence (0.036, displaying noticeable doubling of back facet junctions under 10x magnification), a specific gravity of 3.32 to 3.40, and a Mohs hardness of 6.5 to 7.0.

Geographical Origin & Cultural Legacy: Mined from the high-altitude alpine pegmatites of the Sapat Valley in Kohistan, Pakistan (situated over 4,000 meters in the Himalayas), Pakistani peridot is globally prized by gemologists for producing large, transparent, saturated olive-green crystals. Known in traditional Indian lapidary trades as Zabarjad (ज़बरजद) or Peridot Ratna, it has a revered history dating back over 3,500 years to ancient Egyptian mining on the Red Sea island of Zabargad (Topazios). In Vedic astrology, it is the primary secondary substitute (Upratna) for Natural Emerald (Panna) associated with Mercury (Budh). It is also celebrated worldwide as the official August birthstone. It is customarily mounted in Sterling Silver (925 Silver), Panchdhatu, or yellow gold for rings and pendants.

Care Instructions

• Clean gently with mild soap and lukewarm water, then dry with a soft microfiber cloth.
• Avoid ultrasonic cleaners and steam cleaning; peridot is sensitive to thermal shock and sudden temperature fluctuations.
• Avoid contact with strong household acids, harsh chemical cleaners, and abrasive scouring pastes.
• For regular ring wear, a protective bezel or prong setting is recommended, and the ring should be removed during heavy manual work.
