Detailed Product Description
Natural Ceylon White Sapphire (Safed Pukhraj) – 8.08 Carat (8.88 Ratti)
This Natural Ceylon White Sapphire (celebrated in Vedic traditions as Safed Pukhraj) weighs exactly 8.08 Carats (8.88 Ratti). Sourced from the historic gem gravels of Ceylon (Sri Lanka) and fashioned into a classic Cushion Mixed Cut, this Earth-mined gemstone displays an authentic, colorless white body with natural internal silk and brilliant vitreous luster.
Mineralogical Identity & Physical Constants: White Sapphire is a colorless crystalline variety of Corundum (Al2O3), crystallizing in the trigonal crystal system. With a formidable Mohs hardness of 9.0 (second only to diamond), it exhibits extreme scratch resistance suitable for everyday fine jewelry. Gemological testing verifies a refractive index of 1.762 to 1.770, a dense specific gravity of 3.99 to 4.01, and uniaxial negative optical character.
Cultural & Traditional Context: In historical Indian traditions and classical Vedic Jyotish, White Sapphire is associated with Venus (Shukra) and revered as the premier classical substitute (Upratna) for Natural Diamond (Heera). Customary traditions suggest setting White Sapphire in Sterling Silver (925 Silver), White Gold, or Platinum for Friday morning wear on the ring finger (Anamika) or middle finger (Madhyama) of the working hand.

Frequently Asked Questions
Is this Ceylon White Sapphire 100% natural and unheated?
Yes. This gemstone is guaranteed 100% Earth-mined natural corundum from Sri Lanka (Ceylon). It is completely unheated and untreated, retaining its natural crystal silk and original geological character.
How does Natural White Sapphire compare to Diamond and Moissanite?
White Sapphire is natural corundum (Mohs 9.0), offering superior natural authenticity. While diamonds (Mohs 10) and moissanite (Mohs 9.25) have higher dispersion (rainbow flashes), White Sapphire provides a dignified, silvery-white crystalline sparkle with outstanding durability for lifetime ring wear.
How does Carat weight compare to traditional Ratti for this stone?
This gemstone weighs 8.08 Carats, corresponding to 8.88 Pakki Ratti (1 Carat = 200 mg; 1 Pakki Ratti ≈ 0.91 Carat). Both measurements are explicitly documented on your official laboratory test report.
How is the authenticity and laboratory certification of this stone verified?
Every White Sapphire includes an independent accredited gemological laboratory testing report identifying it as natural white sapphire. If you specifically require an additional report from GII, IIGJ or IGI, you can select it directly from the certification dropdown on this product page upon request (official laboratory testing fees apply in advance on a non-refundable basis).
How durable is White Sapphire, and how should it be maintained?
With a Mohs hardness of 9.0 and no cleavage planes, White Sapphire is exceptionally resilient for daily wear in engagement and astrological rings. Clean with warm water, mild soap, and a soft brush. Rinse thoroughly and dry with a lint-free cloth.
