Detailed Product Description
This Quartz Crystal (Sphatik Stone) weighs 6.31 carat (6.93 ratti) and measures 14.05 x 10.15 x 5.95 mm, a colourless octagon mixed shape. It is of Indian origin, Un-Heated & Un-Treated, and comes with a lab report from The Standard Gem Testing Laboratory, which identifies it as natural rock crystal.
Sphatik (also spelt Sphatic or Spatik) is the Indian name for rock crystal, the colourless, transparent variety of natural quartz. Glass, which the trade also calls "crystal", and laboratory-grown quartz can look the same, which is why every Ratna Gems Sphatik comes with its own lab report identifying the stone. Each stone's appeal rests on its own transparency, cut and size.
Appearance
This stone's report records its colour as colourless / clear. Sphatik is valued for its transparency, and an octagon mixed shape returns light from its facets as the stone moves. Natural quartz can show faint veils or tiny inclusions on close inspection, and the photos and video show this stone's clarity, cut and actual look, so you can see exactly what you are choosing.
Traditional Use
In Vedic astrology, Sphatik is traditionally associated mainly with Venus (Shukra), and also with the Moon (Chandra), and some traditions use it as an upratna, or substitute stone, for Diamond (Heera). Sphatik and Heera are different gemstones. Customers buying it for astrological use usually follow their astrologer's or Pandit ji's guidance. In Hindu custom, Sphatik is also the traditional material for japa malas and Shivlings.
Care
Quartz is hard (7.0 on Mohs scale) and tough enough for a ring or pendant for everyday wear with sensible care. Easy habits keep it bright: clean it with lukewarm soapy water and a soft cloth, and store it separately from harder gemstones such as sapphire and ruby, which can scratch it. Protect it from hard knocks, which can chip a facet edge, and keep it away from heat, steam cleaners and sudden temperature changes, which can fracture quartz. Skip harsh chemicals, and use ultrasonic cleaning only if a jeweller confirms it suits the stone and setting.

Frequently Asked Questions
Is this Sphatik natural quartz or glass?
Natural rock crystal. Your lab report from The Standard Gem Testing Laboratory identifies it as natural rock crystal and records its weight, measurements, colour, cut and specific gravity, all shown in the table above. A laboratory is what reliably separates quartz from glass, which is softer and singly refractive, and from laboratory-grown quartz, which can look identical; that is why every Sphatik comes with its own report, and this one is shown in the photos.
Are Sphatik and crystal the same?
Yes, when the crystal is quartz. Sphatik is rock crystal, the colourless, transparent variety of natural quartz. In the trade the word "crystal" is also used for glass, as in "crystal glass" and "lead crystal", so look for "quartz" or "rock crystal" on the lab report, as this stone's report shows.
Is Sphatik a substitute for Heera (Diamond)?
Some Vedic astrology traditions use Sphatik as an upratna, or substitute stone, for Diamond (Heera); both are traditionally associated with Venus (Shukra). Sphatik is quartz and Heera is diamond, so they are different gemstones. This is a traditional belief, not a promise of any result; customers usually follow their astrologer's or Pandit ji's guidance.
Can this Sphatik be set in a ring or pendant?
Yes, at 14.05 x 10.15 x 5.95 mm it suits a ring or pendant. Choose a secure setting that protects the facet edges, keep it away from heat and hard knocks, and share the dimensions with your jeweller so the setting fits the stone.
