Detailed Product Description
Natural Italian Red Coral (Moonga Stone) – 5.13 Carat (5.64 Ratti) Triangular Cabochon
This Natural Italian Red Coral (Moonga) weighs exactly 5.13 Carats (5.64 Ratti) with calibrated dimensions of 12.8 x 13 x 6.1 mm. Polished into a smooth, lustrous Triangular Cabochon (Tikona Moonga), this Earth-sourced organic gem showcases a rich, natural crimson-red hue, porcelain-like sub-vitreous sheen, and authentic structural grain.
Biogenic Classification & Physical Constants: Unlike crystalline mineral gemstones, precious red coral is an organic gemstone formed from the branching skeletal framework of marine polyps (Corallium rubrum). It is composed predominantly of microcrystalline Calcium Carbonate (calcite, CaCO3) bonded by a natural organic conchiolin matrix. Under standard gemological examination, it exhibits a refractive index of 1.486 to 1.658 (characteristic calcite birefringence with spot reading around 1.658), a specific gravity of 2.60 to 2.70, and a hardness of 3.5 on the Mohs scale. Its surface displays fine longitudinal grooving and faint concentric growth rings diagnostic of natural biogenic origin.
Geographical Provenance & Lapidary Finishing: Sourced from the historical, regulated marine beds of the Mediterranean Sea (Italy) and masterfully worked in the renowned lapidary center of Torre del Greco, Italian red coral is internationally celebrated for its intense red tone and dense structural integrity. This gemstone is 100% natural, untreated, and undyed—completely free from plastic wax filling, dye injection, reconstituted coral powders, or glass resin stabilizers.
Cultural Legacy & Traditional Astrological Lore: Known in Sanskrit as Praval or Vidrum and in Hindi as Moonga (मूंगा) or Marjan, Red Coral is celebrated in Vedic astrology as the gemstone representing Mars (Mangal / मंगल). It is traditionally associated with the zodiac signs Mesha (Aries) and Vrischika (Scorpio), with triangular cuts (Tikona Moonga) holding particular esteem in Jyotish tradition for planetary alignment. In traditional practice, it is mounted in Copper, Panchdhatu, Gold, or Silver and worn on the ring finger (Anamika) of the working hand on Tuesday mornings during Shukla Paksha.

Care Instructions
- Clean only with a soft, clean cloth lightly dampened with lukewarm water. Wipe dry immediately with a lint-free microfiber cloth.
- Because natural coral has a soft Mohs hardness of 3.5 and is composed of calcium carbonate, it is sensitive to chemical erosion. Strictly avoid exposure to vinegar, lemon juice, perfumes, hairsprays, cosmetics, sanitizers, and harsh household chemicals.
- Never clean in ultrasonic cleaners or steam machines. Heat and high-frequency vibration can fracture the organic structure.
- Store separately in a fabric-lined pouch or jewelry box away from harder gemstones (such as diamonds, rubies, sapphires, or quartz) to prevent surface abrasions.
