If you are not buying gold bars or coins...
all the jewelries are pretty much the same...Damas..Allukas etc..

18K price is less..making charge is more...no value for that in India...22k is most liked in India..
24K is more pure..Gold bars are 24k..Coins you can get 22k & 21k

Making charge for Indian Jewelry is QR 15 to 22 per gram...depending on the design...

If you are buying for investment purpose avoid stones...and go for simple designs..
