All Mantra Healed Gem Rings have powers that can effect one’s life for better or worse as it is stated in many of our Our Holy Hindu Mythology Books, Here are few words about Precious Ruby Gem Stone in Our Vedic Literature -

"A ruby, although genuine, should not be worn if it has strong color banding, excessive inclusions within like numerous internal cracks, a sandy appearance, a rough surface, or is dull and lusterless without Proper Mantra Healing. Anyone using such a flawed ruby, even out of ignorance, will  suffer from disease, or loss of fortune."

When Gem Stones and Gem Rings are used for the Purpose of Astrology then it is Very Important to take the Following Precautions, So that you get the desired and Proper results and do not become a Victim of Cheaters and Frauds.

Replacing Synthetic Gems Against Natural Gems

The most common fraud today is selling or misrepresenting of synthetic stones as naturally created ones. As synthetic Stones also contain many elements that are similar to their natural counterparts, like flaws and blemishes, this is the Common Reason why many People donot get Effects after Wearing Costly Gem Stone Rings.

Filling and Heating Original Gems

Another most common fraud today is of Filling and Heating of Original Gems, where Cracked or Stones have Black Spots are Filled, Treated and Heated with Different procedures to Make them look Expensive and to Disguise it's Flaws. Unfortunatley this Fraud is very risky and Bad for the wearer, As sometimes Cracks or Black Spots give Negetive Effects to the wearer.

Cheating & Fraud by Pandits on the Name of Mantra Healing

Even if you wears a Flawless Original Precious Gem Ring, but still it is not Mantra Healed Properly in Different Satges then it will not Give any Results or Effects to You which makes it Equal to a Show Piece or a Ordinary Jewellery. This is an Unfortunate Truth that Out of 10,000 Brahmins Only 6 Brahmin has the complete kowledge of Gem Rings and it's Mantra Healing and Praan Pratishtha of the Gem Rings. So if you are Wearing a Flawless Original Precious Gem Ring and Still you are unable to Feel its Magic Effects then you are surely a Victim of Fraud.
