Jewellery-pendant cross help?

[Rhubarbginn]

I'm looking to purchase a pendant cross for dd confirmation. She is 21 and likes simple delicate jewellery.
Around £200. Any recommendations?

your money will go a lot further on eBay than at Tiffany's!

I looked at the Tiffany one, but the chain is v long! A bit 'gangster'
Any suggestions on eBay or elsewhere?
I quite like the white gold ones. Just not a jewellery shopper
