There are two options for you to buy gold.

1.) Raw gold that is 24 Ct comes in form of coin and biscuit.
2.) Gold ornaments which is varied from 18Ct to 22 Ct. Never ever go for 18ct.

Suppose if you got gold in form of coin and biscuit then most probably you would like to make a jewelry in India and will give this gold to some gold merchant for making an ornament for you If i am you I will never give bcuz you give 24 Ct to this jewelers and you will be not sure to get 22ct gold ornament from there. its my experience and no trader is more smarter then Indian jewelers so they can easily fool you.

Second option is to buy gold ornament for mother and sister which comes in 22ct form which is worth it you will get pretty good design from damas,Atlas and Alukas to name few I trust this as this are brands.

Now the big deal will be on making charges as the making charges are varied from bangles to necklace to sets so you need to be good here to bargain. They will quote to from 8 to 16 riyas per gram for making charge and tell you that they don't get any profit on this there is custom baldiya tax and blah blah..

So u need to do your research for that I found out that 4 Riyals or less are charged as custom duty and .50 as baldiya tax. So u need to be really good bargainer to reduce the cost on making charges.

Go with your instinct and select a design I am sure they will like it a smile on your mother and sis face is not less an achievement.
