Dear Samrat Chowdhury
welcome to the forum.
As per your birth details you have born on Monday under revati constellation pisces zodiac and capricon Ascendant.
You are running with laghu sade sathi shani and from past 2 years you are having huge trouble some. many things were about to finish, however it were not. family, financial troubles. And this situation will end after mid of november this year 2014.
I see for career wise is concerned none of the above stones will help you. And more over red coral is not at all recommended to you. So before recommending you the right one, could you please tell me whether you are working under some one (company) or self employed? And what do you work or type of work?
