I recieved my beautiful sweetie bracelet for christmas with a link and immediatley loved it. Sweetie bracletts consist of lots of tiny silver hoops to attach charms too. They usally cost around £110, and link can range from £45 onwards.
Mine is the medium size as you can get small, medium or large and I had my initail (V) with it. You can attach up to six links yourself but will need to contact Links of London for futher attachments.
This is an ideal present as futher charms can be brought on special occasions, there is such a wide range encluding hearts, a small diamonte ring, a strawberry, an icecream and many many more. This makes each charm indivdual to its owner, representing them and special occasions.
The only bad thing I found was occasionally my little arm hair would catch in it.

This charm also comes in gold, but as you can imagion it is much more costly for the gold version. There is also matching silver sweetie earings, necklace and ring to keep you collecting.
