Detailed Product Description
Natural Red Jasper Stone – 8.63 Carat (9.48 Ratti)
This Natural Red Jasper Stone weighs exactly 8.63 Carats (9.48 Ratti) with calibrated dimensions of 18 x 13 x 5 mm. Cut and polished into an exquisite Oval Cabochon, this Earth-mined mineral specimen displays an authentic, rich terracotta and brick-red hue with subtle natural mineral mottling and a smooth, waxy-to-vitreous luster.
Mineralogical Identity & Physical Constants: Red Jasper is an opaque, microcrystalline variety of Quartz (SiO2) belonging to the chalcedony family. Its distinctive terracotta red color is produced by finely disseminated microscopic iron oxide (Hematite, Fe2O3) inclusions intergrown within the cryptocrystalline silica matrix during sedimentary or hydrothermal formation. Under gemological testing, it exhibits a spot refractive index of ~1.54, a specific gravity of 2.58 to 2.65, and a resilient Mohs hardness of 6.5 to 7.0 with tough aggregate tenacity and no cleavage planes.
Cultural & Historical Context: Red Jasper has a revered archaeological legacy spanning thousands of years. Known in ancient Egypt as the “blood of Isis” and worn as warrior talismans in Greco-Roman antiquity, it has long been admired for its earthy red warmth. In contemporary Vedic astrology, it is occasionally selected as an accessible, earthier secondary substitute (Upratna) for Natural Red Coral (Moonga) or solar jewelry, popularly set in Sterling Silver (925 Silver), Copper, or Panchdhatu.
