Natural Indian Quartz Crystal (Sphatik) 5.83 Carat (6.41 Ratti) Oval Mix Cut

Natural Crystal Quartz (Sphatik) – 5.83 Carat (6.41 Ratti)

This Natural Crystal Quartz (historically celebrated in Indian Sanskrit traditions as Sphatik or Sitopala) weighs exactly 5.83 Carats (6.41 Ratti). Precision-faceted into a brilliant Oval Mix Cut, this Earth-mined rock crystal exhibits outstanding optical water-clarity, high transparency, and an immaculate vitreous polish.

Mineralogical Identity & Physical Constants: Sphatik is a macrocrystalline mineral variety of pure Silicon Dioxide (SiO₂) crystallizing in the trigonal crystal system. Gemological evaluation verifies a refractive index of 1.544 to 1.553 with a double refraction (birefringence) of +0.009 (uniaxial positive character displaying the diagnostic “bullseye” optic axis interference figure), a specific gravity of 2.65, and a resilient Mohs hardness of 7.0. Exhibiting superior thermal conductivity compared to amorphous glass, genuine Sphatik remains noticeably cool to the touch and easily resists standard atmospheric abrasion.

Cultural & Traditional Context: In historical Indian traditions and classical Vedic astrology, natural clear quartz crystal is associated with Venus (Shukra) and revered as an esteemed traditional alternative (Upratna) for Diamond (Heera) and White Sapphire (Safed Pukhraj). Customary traditions suggest setting Sphatik in Sterling Silver (925 Silver), White Gold, or Platinum for Friday morning wear on the middle finger (Madhyama) or little finger (Kanishtha) of the working hand, or worn as a pendant.
