I was suggested to wear a gemstone - The Blue Sapphire (Neelam). I went to the shop and bought it but it was not blue color to my thought that all blue sapphire must be of blue color. Mine was dark green color. I don't know if this is other stone. I came to know that this gemstone is the strongest and the fastest acting one among the nine planetary gemstones. I didn't get such actions during its 'test' phase and after wearing the stone in a silver ring. May be it will show its effect in coming days or showing its effect without my notice.
The seller told me that the stone is best from Nepal and very expensive. While searching the literature, I came to know that it is found in Kashmir, Lanka, Russia, America etc and the best Sapphires are found in Lanka.
If you are also wearing this gemstone, please share your experience and its effect to you.
