Help gift ideas please?

I am so stuck with what to get dm, I was going to get Molton Brown gift set and a gift voucher for a shop she likes but it seems abit boring and thoughtless and I dont think she would realise how much the molton brown set is. So back to square one?!
She does like jewelery but I cant afford something ridiculous so I was looking at these? www.swarovski.com/is-bin/INTERSHOP.enfinity/WFS/SCO-Web_GB-Site/en_US/-/USD/SPAG_DetailPage-ViewPage?SKU=1062708

Do you think there abit naff though, I would love to get her something from Tiffany and co (would like something from there myself) but not sure if it would look too small.

I hate buying for adults!

What's your budget for her, and where does she buy her own jewellery from? For me, the tiffany necklace is too insubstantial for the £100 price tag, but then I wouldn't spend £100 on my DM unless I was getting her a new TV / video or a spa treatment / mani + pedicure - something more tangible.

You've mentioned jewellery but what are her interests? Could you buy something to complement them?

Im not too sure really she hasnt bought herself any jewellery for a long time. For the past couple of years ive got her a Radley bag and matching purse for her Birthday which she has loved and used everday since but I wanted to get her something different this year.
I like to spend abit on my dm as she has so many grandchildren etc to buy for and she always thinks about others so I like to return the favour.
