As per the Internet Padpardascha is derived from a Singhalese word, it does not seem to be a popular stone in North India from where I am. I cannot figure out what this stone is about. If you can let me know which Grah or planet it is for I can suggest other options. Or if you can let me know the North Indian name of the stone, probably I can find more and will try to help you on this.
actually me also come to know about this Stone from north India(Delhi).I only know the name as padpardascha or orange sapphire or Padmaraga.so I want to know more about this stone. I had also search it on Internet.
if u will come to know About it.let me know sir.
