African Gomed Stone 9 Carat (9.89 Ratti) Natural Certified Hessonite

Natural African Hessonite Stone (Gomed Ratna) – 9.00 Carat (9.89 Ratti) Oval Mix Cut

This Natural African Hessonite Stone (Gomed Ratna) weighs exactly 9.00 Carats (9.89 Ratti) with calibrated dimensions of 13.8 x 10.9 x 6.2 mm. Expertly faceted into a brilliant Oval Mix Cut, this Earth-mined garnet displays an authentic, warm cinnamon honey-brown hue with vibrant transparency, lively vitreous luster, and the diagnostic internal "treacle" effect characteristic of high-quality grossular garnet.

Mineralogical Identity & Physical Constants: Hessonite is the cinnamon-colored grossular variety of the Garnet (calcium aluminum silicate, Ca₃Al₂(SiO₄)₃) mineral group. Its distinctive golden-brown to brownish-red color is produced by trace trivalent iron (Fe³⁺) and manganese (Mn) replacing aluminum in the isometric crystal structure. Under microscopic examination, natural hessonite exhibits a diagnostic "roiled" or "heat-wave" appearance (the treacle effect) caused by microscopic diopside and apatite inclusions. Under gemological testing, it displays an isotropic single refractive index of 1.740 to 1.750, a specific gravity of 3.59 to 3.68, and a resilient Mohs hardness of 7.0 to 7.5 with no cleavage planes.

Cultural Legacy & Traditional Context: Known across ancient cultures as Cinnamon Stone and revered in Indian lapidary traditions as Gomed Ratna, Hessonite holds an iconic position as one of the sacred Navratnas. In Vedic astrology, Gomed is the principal planetary gemstone for Rahu (the north lunar node). It is customarily set in Sterling Silver (925 Silver) or Panchdhatu for rings and pendants, with open backings that allow natural light transmission.

Care Instructions

• Clean gently with mild soap and lukewarm water, then dry with a soft microfiber cloth.
• Avoid sudden thermal shocks or steam cleaning; high temperature extremes can stress natural garnet crystals.
• Avoid exposure to harsh industrial chemicals, strong acids, and abrasive scouring pastes.
• Store separately in a soft fabric-lined jewelry box to avoid surface scratches from harder gems like sapphire or diamond.
