Thank you for everyone who responded. My Grandmother is against me giving the ring (only for Moon Dikhai) may be some tradition, may be some superstitious stuff but she would not tell me and I would not rather not argue much or go against her wishes.... Almost all my friends who got married in Pakistan give a solitaire ring because no one did the same on thier engagement (including me) but since that is out for me thats where the confusion started
I would have thought about studs, but after trying to get her preference for jewelry overall, it seems she does not like tops.She has not been in states or any other European country before so may be after living here for a while, she would like them.. but then I can give them on some other occassion later in my life.. Simiarly I am not sure she would be that much into Silver (even from Tiffanies)...I know she likes 22 ct gold and even take some to digest 18 ct.
It seems that overall a bracelet would be her favorite piece of Jewelry and I think she wouldn't mind the pendant either but living in Pakistan not sure what would have the "wow" effect... Also can one wear a bracelet every day. ? Its very easy to find and discern a good quality solitaire (buy them certified etc) but I am not sure about the bracelet and worried about the size...
