This Natural Brazilian Citrine (Sunela Stone) weighs exactly 4.35 Carats (4.78 Ratti) with calibrated dimensions of 11 x 9 x 6 mm.

Mineralogical Identity & Physical Constants: Citrine is the yellow-to-golden crystalline variety of Quartz (SiO₂). Its warm golden coloration is caused by trace ferric iron (Fe³⁺) impurities dispersed throughout the trigonal crystal lattice. Under gemological examination, it exhibits a refractive index of 1.544 to 1.553, a specific gravity of ~2.65, and a resilient Mohs hardness of 7.0 with no cleavage planes, providing superior scratch resistance and longevity for everyday fine jewelry wear.

Cultural Legacy & Traditional Context: Known across ancient cultures as the “merchant’s stone” and celebrated in Indian lapidary traditions as Sunela or Sunhela Ratna, Citrine holds an honored position in gemology. In Vedic astrology, it is the primary secondary substitute (Upratna) for Natural Yellow Sapphire (Pukhraj) associated with Jupiter (Guru / Brihaspati). It is also celebrated globally as an official November 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 exposure to extreme heat, steam cleaning, or prolonged direct sunlight, which may alter golden quartz tones over time.
• Avoid contact with harsh household chemicals, strong acids, ammonia, and abrasive scouring pastes.
• Store separately in a fabric-lined jewelry box to prevent surface scratches from harder gems like sapphire or diamond.
