Bollywood Celebrities' Astrological Gems

Why do these people wear gems?
When you are at that level of success and have money to make your life perfectly happy and also don't want to take any chances, then....why not, if there is an astrological remedy existing for your life's troubles.

Vedic Astrology and Vedic gemology has very little or nothing to do with your "religion". The basic faith needed is faith in the science and the astrologer.
Emraan Hashmi, a muslim actor from Bollywood wearing 4 gems, in the astrologically appropriate fingers. Middle finger has an Ethiopian fire opal. Ring finger has two corals. Index finger has fabulously expensive 7 carat natural yellow sapphire.See here and here 

Irfan Khan, a muslim actor wearing a Blue Sapphire correctly in what is generally Saturn's designated finger, the middlefinger, though there can be exceptions. See here

Allah-Rakha Rahman (A.R. Rahman), a muslim Oscar winning Bollywood music composer wearing a gemstone (Blue sapphire set in white gold). Set in white gold which as ordained by the vedic astrological scriptures, is the most perfect metal for setting this gem in. See here (BTW, the one that is frivolously depicted in this URL next to the A.R.Rahman is s lab made stone, only a careless gemseller would make this move of putting lab-made/fake gems on his website, shows to me that the person's not that bright.)

Shahrukh Khan, muslim actor, wearing a 10 carat coral in ring finger and a 7 carat emerald in pinky finger.  See here

Amitabh Bachchan seen with dual rings of blue sapphire each of 10 carats. And pinky finger dons a 13 carat emerald. See here 
It would be in general unwise to don a astrologically permitted and specifically a mantraized gemstone in the left finger, few exceptional cases exist. Maybe he wore it just for that pic to make it more aesthetic and then immediately after the photo-shoot removed it and located to the right hand where it was meant to be put on.

Sanjay Dutt wearing a 12 carat pearl for his mental stability, addictions and anger management issues. Set in silver and in the pinky finger, as it is scripturally ordained. And also a  6 carat yellow sapphire See here

Aishvarya Rai Bacchan wearing  7carat blue sapphire and a opal See here

The now deceased BJP leader Gopinath Munde, wearing a yellow sapphire of 15 carats. Set in gold as is scripturally advised. A gem of this category will cost nothing short of a crore rupees or 200k $. But his work deals with thousands of crores so, a few crores spent on a gem is pennies for him. See here

Ekta Kapoor, Indian daily soap opera mogul, sporting 9 gems. See here and see here

About the right hand:
index finger has a 12 carat yellow sapphire which appears to be an untreated gem, this given it's quality will start at 2 crores (300k$) minimum. Ring holds what appears to be a very light colored Sri Lankan untreated 12 carat blue sapphire with a white sapphire next to it. If this were so it is not recommended. But in an exceptional case for a Blue Sapphire the ring finger will do.
Pinky finger has a dark emerald with a pearl.

About the left hand:
Pinky finger has a light colored emerald set in gold, which is appropriate according to the astrological scriptures.
Ring finger holds a 13 carat diamond.
Index finger has a 15 carat yellow sapphire.
Middle finger has a 12 carat Ruby.

Expect for the diamond each gem worn has to be minimum 1 crore (150K $), the diamond will be anything from 200k $ to 1.25 mil $ depending on the clarity, color, cut, fashion house/artist which cut it and fashion house which sells is.

A light yet (almost) crystal clear emerald of 9 carats may cost about 2crore (300K $)
A 4 to 5 carat pigeon blood untreated Myanmar (Burmese) ruby of what one may call the international grade may cost around 2 crores.

So one can simply estimate how much her gems cost.
