You could have everyone in the family who are close to her write a letter and include their favourite photo of her. Scan them all and pop them in a photo book (like with mixbook or snapfish), get it put together and she’s got a beautiful gift celebrating her and the relationships she has.

Does she like jewellery? Perhaps some nice earrings, watch or a necklace to wear that she will always remember you by. I made up a glory box for my sister, I filled it with heirlooms and antiques and the case was an antique too. She loved it!

I think you could ask her mum if she knows what she’d like or you could get something with sentimental value in years to come.

For my 21st I had to make my own video of growing up and I was sad about that because I felt like I was the only one excited. Maybe, if you have photos to make one if you know how to or someone else knows.

I can also suggest a shadow box? I really cannot explain for the life of me what it is but if you google it, there are amazung ideas! You buy the frame itseld from kmart

This is such a hard one to answer for those of us who don’t know your daughter. You need to choose something that would be meaningful to you and your niece

As a female from a very sentimental family I got so many random “keepsakes” for 18ths and 21st like the glasses and keys etc. I haven’t kept most of that stuff in my adult life as its not something I display so sits in a box, to me the most sentimental items I treasure are jewellery and can remember who gave me each pandora charm I own and for what occasion. Its something now as a mum of 3 girls i’m cautious of so have just got them a pandora charm bracelet that I can add to for special occasions.

I tend towards a keepsake or luxury gift for milestone birthdays (watch, bracelet, necklace). Otherwise a night in an all-inclusive stay at a luxurious hotel. If it’s an experience gift, it has to go all the way to be memorable

I’m reall sentimenteal with things like this I would get something with a 21 on it like a pendant or charm, a glass, a key that can be signed by people all that have 21 on it (you used to be able to get those keys from from gift stores etc)

I always like the idea of a locket or piece of jewellery that your niece will keep and hopefully wear for years and years.

I think something from Tiffany would be lovely.. maybe a Kate Spade handbag.

First Tiffany piece (under $200 for a charm etc) or first bottle of Chanel perfume (under $150 for small bottle of Coco or No. 5), if you can afford it I think it’s a lovely extravagance that they might not do for themselves.

An experience is a great gift.she will forever remember this. Maybe something you can get involved with too.

A charm bracelet with charms that are personalised to her – travel, times together etc might be nice?

I’d suggest a necklace or a beautiful photo frame.

A piece of jewellery is always a great keepsake

I would find out what she is into, a nice jewellery box from a good jewellery shop that is if she likes that sort of thing. Another thing if she has long hair some jewellery shops used to sell nice things to put in your hair.

Maybe a Pandora charm, a watch, necklace, or something engraved with her name ….

Personalised jewellery is great, and these days there are lots of options.

A memory could be just as beautiful as a keepsake. If there is an experience your neice would love do it with her and get photos she’ll treasure forever.

Jewellery is always special and a gift she will have forever.
