Detailed Product Description
This Natural Red Jasper Stone weighs 10.40 carat (11.43 ratti) and measures 19 x 12 x 5 mm, an opaque round cabochon in red and black. It is Un-Heated & Un-Treated, and comes with a lab report from Neel Gems Testing Lab (AN ISO 9001-2015 CERTIFIED LAB), which identifies it as natural jasper.
Red Jasper is an opaque variety of chalcedony, the fine-grained form of quartz (silicon dioxide), coloured red by finely dispersed iron oxide; darker bands and patches are common, so no two stones look alike. In the trade, some jasper is dyed or stabilised with resin, and dyed howlite, magnesite and quartz are sometimes sold as red jasper; a gem testing laboratory tells them apart, which is why every Ratna Gems Red Jasper comes with its own lab report.
Appearance
This round cabochon has a smooth, polished, opaque surface with red and black banding. The pattern is part of the stone's character, so every piece is its own, and small natural surface marks are not damage. The photos show this stone's colour, pattern and polish, so you see exactly what you will receive.
Traditional Use
In Vedic astrology, Red Jasper is traditionally associated with Mars (Mangal). In Vedic tradition it is often listed among the upratnas, or substitute stones, for Red Coral (Moonga), together with carnelian, bloodstone and red agate; Red Coral remains the main gemstone for Mangal. Red Jasper is a different gemstone from Red Coral, not an equivalent. Customers buying it for astrological use usually follow their astrologer's or Pandit ji's guidance.
Care
Jasper is a hard, tough quartz-family stone with no cleavage, so it suits a ring or pendant, and a few easy habits keep it looking its best. Clean it gently with mild soap, lukewarm water and a soft cloth, and dry it straight away. Keep it away from knocks that could chip a cabochon edge, and, because jasper can be dyed or stabilised, from acids, acetone, alcohol, perfume and other harsh chemicals, prolonged soaking, sudden temperature changes, and steam or ultrasonic cleaning. Store it separately in a soft pouch, and take a ring off for heavy work or sport.

Frequently Asked Questions
What does the lab report say about this Red Jasper?
Your lab report from Neel Gems Testing Lab identifies this stone as natural jasper and records its weight of 10.40 carat (11.43 ratti), measurements of 19 x 12 x 5 mm, cut, colour, refractive index and fluorescence shown above. The report card is shown in the photos.
Is red jasper ever dyed or imitated?
Sometimes, which is why every Ratna Gems Red Jasper comes with its own lab report. Red jasper takes its colour from iron oxide, but some jasper is dyed or stabilised with resin, and dyed howlite, magnesite and quartz are sometimes sold as red jasper. Your stone is Un-Heated & Un-Treated, and its accompanying lab report identifies it as natural jasper.
Is Red Jasper the same as Red Coral (Moonga)?
No. Red Jasper is a quartz-family stone, an opaque form of chalcedony, while Red Coral is an organic material formed by marine coral animals. In Vedic tradition Red Jasper is listed among the upratnas for Red Coral, and some buyers choose it on their astrologer's advice, but it is a different gemstone, not an equivalent.
Which planet is Red Jasper associated with?
Mars (Mangal). In Vedic astrology, Red Jasper is traditionally associated with this planet. This is a traditional belief, not a promise of any result, and customers usually follow their astrologer's or Pandit ji's guidance.
Can this Red Jasper be set in a ring or pendant?
Yes, at 19 x 12 x 5 mm it suits a ring or pendant. Share the dimensions and the cabochon height with your jeweller so the setting is made to fit the stone, and the easy-care tips above will keep it looking its best.
