Hessonite (Gomed) : This gemstone belongs to Rahu (North Node) and varies in colour from light honey colour to dark honey colour.

It can cause ulcers, tumors, cancers, madness among other things. And in my experience it is not suitable for at least 70 to 80 percent of people. So be very careful while wearing this Gemstone and monitor its effects closely for some days and weeks even if it is prescribed to you by some expert Astrologer, and in case you find some unusual things like sudden misfortunes, sudden diseases, extreme short temperedness and insomnia, take it off. It is generally worn on the Middle finger and it should be worn on the day prescribed by the astrologer.
 

Blue Sapphire (Neelam) : The most enticing, the most mysterious, the most feared, and perhaps the most effective of all the Gemstones belongs to none other than Saturn.

It varies in colour from light blue to deep blue. This gemstone can bless you with wealth, health, luxury and so many other good things. But it can be very destructive if not suited to a native. It is generally worn on the Middle finger and it should be worn on Saturday morning after prayers.
